- If 6 + 4 = 210, and 9 + 2 = 711, what is the rule to combine numbers? This "intelligence test" has been shared more than 3 million times on Facebook. On Twitter people claim solving it means you have an IQ of more than 150 (genius level). In this video I ask a question to test if you really understand the rule. As the original test asks, "Share if you understood it."

Here's another challenge. The original test had these equations:
6 + 4 = 210
9 + 2 = 711
8 + 5 = 313
7 + 6 = 113
9 + 8 = 117
10 + 6 = 416
15 + 3 = 1218
Are there any other ways to get the same result? For example, we can also get:
10.5 + -10.5 = 210
Solve for the other cases.
9 + 2 = 711
? + ?? = 711
8 + 5 = 313
? + ?? = 313
7 + 6 = 113
? + ?? = 113
9 + 8 = 117
? + ?? = 117
10 + 6 = 416
? + ?? = 416
15 + 3 = 1218
? + ?? = 1218
What about multiplication and division
+MindYourDecisions
17 + (-14) = 313
7 + (-4) = 113
9 + (-2) = 117
23.5 + (-17.5) = 416
109.5 + 108.5 = 1218
64.5 + (-56.5) = 1218

617287.5 + -617279.5 = 12345678
6172839 + -6172839 = 12345678
What about
x+y=123
And x-y=0
The third solution would be x=61.5 and y=61.5
And you have 61.5(+)61.5= 0123 = 123
However, there is no fourth solution like that because 123|0 =/= 123
I got thrown off by "? + ??" i though it was a one and two digit numbers.

Exactly the same problem here, the two question marks are confusing.
High IQs are underestimated. This one is way too easy for 150+
It’s just that all the popular internet intelligence tests can be easily solved quickly (in this one it takes
Once hawking said, IQ makes you a sloth who vaunts to be a well-known forsaken genius. Believe on yourself, if there is something impossible, it is just just the noun "I cannot", if you despise that then you are the true genius.
I agree
Yeah I'm like average and it took me like 10-15 seconds to figure out the rule
@@BananaWasTaken as you (kind of) say, the internet tests are just throwing in a high IQ number to get people enganged - and that's the purpose of them; to get people to share, reply and interact, and through this build profiles and monetize these profiles through advertisements.
If you understand this you have an IQ more than 15. He added an extra 0
Just like he had with the extra question mark
@@SomeRandomGtaDude-zl3us True. They restricted the accounts of anyone with half a brain.
No, he multiplied it by 100. Its actually iq 1.5
I simply cannot believe, that this test should indicate a genius IQ of 150+
This is way to easy... I figured it out within 2 seconds...
Same here less than a minute.
Then describe how you figured out the problem.
I figured it out using the thumbnail. Lol
Me too
mah, they just always make a title like that to a test similar to that one, just to gain some fame. its the same with these online iq tests. for example: you finish iq test rezulting in 130-99999iq then you are going to tell your friends about it and they are going to try this test too. And becouse of this you just hear kids braging about that they have 420iq or whatever iq that is supposed to be high compared to other rezults or something and the creators of those tests are going to make some money from these tests by runing ads, unless everyone will have ad blockes.（those numbers are indeed random and made by me, but its the example）. sorry for grammar
This took me like 10 seconds to figure it out.
Same
+Too Boss MC (2BossMinecraft) I only looked at the first and second and the patern was just way too obvious.
+Too Boss MC (2BossMinecraft) looks like the people on facebook aren't too smart.
your amazing
I'm 13 and figured it out as soon as I saw all the numbers
His test had ?+?? So I thought the first number must be a single digit an the second two digit number. But that had nothing to do with it.
same
Do you know what "thought" did...? he thought he farted but he pooped himself.... lol....
same... i did understand the rule but not how to solve the problem
same, I got annoyed so i did 12 and 11 thinking I failed.
His problem WAS misleading with the ?+??, I came up with the numbers he had but felt it was wrong thinking the first one was supposed to a single digit.
I can't believe I actually solved it! :D But at first the question marks confused me.
Exactly the case with me
I think it's sorta of an index, like:
n1 + n2 = 748
? + ?? = 748
If I were to extend it, it'd look like this:
n1 + n2 + n3 + ... + ni = 748
? + ?? + ??? + ... + ?^i = 748
I have solved it
I think IQ tests are usually very limited. Doing them more than once usually make it much easier. Also intelligence is a very broad subject and people are better and worse at different aspects of thinking.
So, I must admit I found this as one of the easiest questions you have ever posted. I was able to see the rule in seconds and did not even need to pause to understand the rule for the "Intelligence test" as it is being called. I immediately thought of 11 and 12 for the following question you proposed however the ? + ?? lead me to believe that the first number would be a single digit while the second would be two digits. I think the way you proposed your questions with the single and then double question marks ask for a different solution. I did pause at this point to try to figure out the solution and upon giving up, I played the video and found I was indeed correct but over complicated it myself.
I truly enjoy your videos and all the questions your propose here. Keep up the great work!
As for this one, based on the ease and speed I was able to find the solution I would not say you need to have an IQ of over 150 to understand it.
whats your IQ?
@@ILoveLuhaidan lol
It is easy, but thumbnail confused me. My first thought was about "hmm, 6 + 4 = 210. Easy to see, that 6 + 4 = 10, and 2 = GCD(6; 4). So 123 = x + y => x + y = 23 and GCD(x; y) = 1 => (1; 22), (22; 1), (11; 12) and etc."
So you started playing the vid right?Didnt just get it from the thumbnail
yeah ? and ?? made me work for next logic for a lot of time
I figured it out, but I was really confused by the ? and ?? placeholders. I thought this represented one and two byte numbers, respectively.
fyi bytes and digits are distinct things. decimal 10 is typically a 1 byte number
yes me too
same here -_-
me 2
That's the reason why I couldn't solve the problem too
Confusing because ?? looks like it should be a double digit number. Why not pose the question _ +_ = 123 or even ? +? = 123
I figured the first single digit number minus the first digit of the second number would 1, and the first number plus the entire second number would be 23.
3 + 20 = 123
3-2= 1
3+20 = 23
If ? + ? = 123
Then ? Is common in adding 123
It's like x + y =123
But not x + x= 123
Omg it's you I'm your fan
Why is it 3-2 not 3-20
Its 12+11=123
Wait im rightt
Hey,
I easily solved the problem, but I found it confusing when I got to the part where there were one question mark and then two. I knew that it was supposed to be 11+12=123, but I was still having a hard tim figuring out why it was like that. I no matter what want to say that you are making a lot of good videos with great problems in mathematics.
Keep up the good work!
All the best greetings from Denmark
I said 11 and 12 instantly but the format of ? + ?? through me. I interpreted it as a single digit number and a 2 digit number, which made it unsolvable. +MindYourDecisions pls use proper variables.
+Brian Troy Same here
+Brian Troy I figured you just subtracted the first digit in the second number so if you have 3+20 then you get 3+20= 23, and then 3-2 =1 which gives 123. Its not confirmable though since in non of the examples the second number of the addition is a doubledigit , and it seems kinda odd now that I think about it, anyway why we bother, everyone that gives this a try already knows they are geniuses
I also interpreted it that way. If he meant just two any numbers, why not to write "? + ? = 123"?
Writing variable amount of "?" suggests that number of "?" signs matters.
+jarlfenrir I guess since ? is a variable having ? appear in 2 places implies the 1st and 2nd are the same number
same with the ?s.
I'm a 12-year-old, didn't even need 5 second to understand -.- And my IQ's definitely not >150
It would be more interesting to show calculations like 8 + 13 = -521 or 6 + -3 = 93
Same I'm 14 and I figured it out fast but I think my it would be like 130-140
if u can solve this problem it doesnt mean ur iq is higher than 150. the the usa they just dont have an other expression than "genius" for ppl with an iq of more than 130 (maybe, coz they got such a lil nr of those though...)

+Yousif Badaway if u rlly wanna try sth hard i would recommend a chinese test ( its called like :" can u find the total area of the red spots" or sth...) it requires a lot of knowledge u may not have so dont be disappoimted if u cant solve it :)
I actually thought of two interpretations of this. I have noticed that of the numbers given, the first one or two digits make up the difference of the number pair, while the last one or two make up the sum. The first interpretation says that we need the difference of the two numbers to be 12 and the sum must be 3. Let us keep in mind that no explicit rules have ever been given that say that both numbers must be positive or even whole. After trying out different number combinations, I got 7.5 - 4.5 = 123. This works because the difference between 7.5 and -4.5 is 12 (7.5 + 4.5 = 12) and the sum of them is 3 (7.5 - 4.5 = 3). The second interpretation is the easier of the two, stating that the difference of the two numbers must be 1 and the sum must be 23. The solution here is 12 + 11 = 123. The difference between 12 and 11 is 1 and their sum is 23, so this solution works as well.
The first digit, is the subtraction, of the two numbers, the second digit, is the addition of them.
Am I a genius or this test is actually very simple ? O_o
Last digit(s) = sum
First digit(s) = difference
actually very simple..
simple very simple!!
Stop acting. You Googled it. You don't need to lie
so your answer is not related to the fact that this guy said first do plus than do minus
i rlly think u could be a genius coz if u take a look on the clicks its about 1.1m and the comments are pretty rare... meanwhile ppl who cant solve it dont comment
Yooo why you put 1 question mark in the thumbnail?! It made me think it was one number, then two numbers. I understood the 6+4, but I couldn't find a solution with one number + two numbers.
+PianoTutorials333 I agree, asking for ? + ?? was misleading. It made me look for a one-digit number and a two-digit number, which does not work.
+PianoTutorials333 Exactly, this was my problem too. Should've used x and y instead ... but nothing's perfect.
So...the answer is 11 and 12 right...
11 + 12 would give -123, I think.
+Daniel Houck I mixed it up lmao ;-;
I was able to solve these problems pretty quickly, however, your equations are what I have a difficult time with.
12+11=123
Yes!!!11!1!11!1!1
This proves nothing about IQ since I solved this problem in the first two seconds of the video but I'm stupid as fuck.
Amen
lol same
Come on. I really hope you're not soooo stupid...for I was needing about five second.
First of all, a common misunderstanding about IQ is that it's how smart you are, but it actually means how fast you learn/how logical you are. So if you can solve 4!, that has no effect on your IQ. But, if you can solve 567,483,654,378,658,439 + 56,473,865,473,826,476,382 in a matter of seconds, that means you have a high IQ.

I didn't solve it because I was under the impression that "?" represented a one digit number and "??" represented a two digit number.
+Frample Tromwibbler I had the same problem, i solved the normal one, but couldn't solve the question with ?+??=123 because of the same reason as you mentioned. I was also searching for a one digit number.
+Frample Tromwibbler Same here! I kept thinking throughout the video some intelligent solution will be revealed. But it ended just like many other videos of this channel. With loads of douchebaggery!!
+Frample Tromwibbler i got the trick after 10 sec and since i couldn't make a 1 digit number and a 2 digit number work i spend half an hour looking for another answer thinking there was another formula of the 2 input values that (intentionally) coincidental happened to fit the obvioius formula as well.
time poorly spend
+Florian van Citters I saw the correct answer and end up writing but I was also momentarily confused by the ? + ?? = 123. The way he presented the problem in an incorrect way.
i had the same problem. i figured out that 12 and 11 works tho
before watching explanation: first number(s) is/are formed from the difference. Second numbers(s) is/are formed from the sum.
11 + 12 = 123
You’re wrong, you’re right in how to get the answer, but its 12+11 not 11+12, you said first numbers are formed by difference, 11-12=-1 and 11+12=23 so the answer would be -123, but with 12+11, first 12-11=1 then 12+11 making it 123.
Thats why i think you just watched the videos explanation of how to do it, think you got it, did it incorrectly, then said you got it before watching explanation
It wasn't hard to figure out but your ? - ?? = 123 is misleading. It gives the impression that the first number is a single digit and the next one is double digit and therefore makes the puzzle unsolvable since any variation of ? -?? would equal a negative number
no way can my IQ be more than 150. figured this out in seconds.
Me too
+Annoying Miner101 same.
I mean, I do have an IQ of 137, but a 150!?!
Me too, I got it in seconds and I AM 12!
Yeah your name screams of intelligence
I’m proud (and kinda surprised) that I was able to find the pattern and the first solution. I figured out the second one right after you explained the first one lolol.
The preamble contains only counting numbers ie positive integers. So there is no good reason to suppose a 'correct' answer might comprise negative irrationals.Examining the given information suggests rejecting the latter, in fact, as a well-formed test must provide complete information needed for its solution. Absence of fractions and negatives in the extensive pre-amble implies these will be wrong answers.
? + ?? = 23
You tricked me, I assumed that the first number would be between 0-9 and the second 10-99
I'm tired though, but I did solve the question in a matter of seconds.
+CruelFish I assumed the same thing, and concluded that it was impossibe. :( It's a badly presented challenge because he didn't explain the non-standard notation.
So much this - mind your notation if you're challenging people to actually solve what you're presenting.
Same thing happened to be. And even then, it was pretty easy. This is just another "trendy" Facebook post...sigh
I thought the single question mark meant a one-digit number so I got confused
+80greaty me too -.-
+80greaty me too so my awnser was that is is impossible :P
+80greaty
Yeah, it's very confusing that he used two questionmarks for y and just 1 for x. So 1 digit number + 2 digit number = 123. Very confusing
+80greaty Me too, so the answer i came up with was 12 + -11 = 123 . Obviously wrong because it doesn't match the rules, at the time i was just thinking 12+ (-11) = 1 and 12 - (-11) =23. So 12+ -11 i guess would be 231. I also didn't bother to check for the secondary answer. I must be dumb.
+80greaty You're not the only one, mate. I thought that too. I figured the rule in like 5 seconds, cuz it's really easy. And spent around 5 minutes trying to wrap my head around a 1 digit and a 2 digit number that make 123. @MindYourDecisions, construct your questions better! use x and y or something next time.
had you asked ? + ? = 123 i would have gotten both but neither answer fit ? + ?? = 123
both fit ? + ? =123 (can be interpreted as x+y) but the ?? supposes two elements to find, either digits or possibly elements to expect ?? to interpret as -1*4.5 is too much of a stretch for the lowly language operator
so your answers would fit ?? + ? for first but second ??? + ???? (digit, sign and decimal point are all different elements to group together you use only a single ? not ?? which implies elements of two)
I didn't attempt to get the numerical value of the second set of numbers but I figured you have to take 12-3 into consideration since you gave a hint of "trap answer".
Here is another set 61.5 + 61.5 = 123, x-y = 0, x + y = 123
I think it was just made easy.
Text said you have 150+ iq.
You got excited.
You shared it.
This is all, it was just a lie to make people share it.
And it worked pretty well.
3 + 20 ? The 12 + 11 doesn't work if the number of question marks is a factor.
agreed
+croshad Yeah, that stumped me too. But wouldn't 3 + 20 = - 1723 ?
3+20 I think
The two question marks don't mean it's a two digit number, it means it's a different number that the first one
+omniflas _ it would, that's the downside of the hypothesis but since this is a precedent (1+2 digits) we can only speculate and this seemed logical
Solved it!thank you for being our inspiration!
I actually did get to solve it right away. The only thing that tripped me up was I didn't think of using negative numbers as a possible solution to the proposed equation.
I had an issue with the "? + ?? = 123" expression. I thought I had to find a solution with an one digit number (0-9) as x (or the "?") and a two digit number as y (or the "??"), I just ignored that the two terms simply had to be different numbers.
Therfore I understood the problem and its solving process, but I couldn't find any numbers that could fit in the "? + ?? = 123" expression.
you fked it up with the ? and ??. still love your work! appreciate the time and brain you put into it.
The answer is 12 + 11 = 123. I answered by noticing that a + b = the last two digits while a - b = the other digits. Such as 9 + 2 = 11, 9 - 2 = 7, 711
You're right. You should be able to understand and explain how you've solved the equation. You'll always have those that say "It was easy" but you've figured out how to weed those out that actually do. Awesome. Love your channel and have learned alot. thanks
this is waaaay too easy to be a 150 IQ question, it's more like a "you're not a moron" question...
I think there's two more solutions because either the difference can be 0 or the addition can be 0. f.e. 61.5 + 61.5 = 123 (61.5 - 61.5= 0 and 61.5 + 61.5 = 123 so 0123 0 you can leave out so 123 just the same counts for -61.5 + 61.5 = 123
Pattern: first digit(s) are subtraction from the numbers on the left, last digit(s) are addition of the left so i would say answer is 12+11
I figured out the rule pretty quickly but I dont have paper so it took me a minute to solve he system in my head
Same ! I got the first solution very quickly then I found the negative number solution but was very confused by the ? + ?? (suggesting one and two digit numbers) so I thought this was not the right answer until I actually watched the video.
You threw me off with the one question mark and the 2 question marks (?+??=123) I thought that meant that the first one had to be one digit and the second two
The numbers subtracted before the numbers added.
Which means that to get 123 your two numbers are 12 and 11.
The test is fairly simple if you understand the connections between the two numbers and the answer. For example 1, 6 and 4 and to give 10 and subtract to give 2, thus equals 210. So in 123, two numbers that add to give 23 and subtract to give 1 are 12 and 11. Wait if I got this one straight away, does that actually mean I may have a genius IQ of 150?
if this is a 150 IQ then I've lost all faith in humanity.
I thought "?+??" suggested that the first number should be one-digit and the other two-digit, so I couldn't solve it.
Thanks for revealing it because you said that I rushed myself, I won't do it again though
first digit in the answer is the two numbers in the sum subtracted by one another and the last two is the sum of the two numbers in the addition problem. 12+11=23 12-11=1
I looked at it and figured it out. I'm pretty good at finding patterns in numbers though because in my calc course, I always got huge assignments with seemingly tedious practice. I started clicking in help me solve this portion of the problem to see another version of the same style of problem, and then I'd just apply the general patter to the original problem until I got the correct solution. I did this with nearly 100 of the 160 total problems in the course, and it strangely benefitted me with number patterns. Even cheesing can make you smarter!
I tried to solve it just seeing the thumbnail,then played the video and immediatly after looking at 5+2 i solved it,i just realized immediatly
dude sometimes you need to be more precise... you just can't put one question mark and then double which also means you need one digit and then two digits...I got that answer way back but I got so confused and thought that I was the dumbest person in the whole world...well commenting here about my capabilities doesn't make me any better, but I just realised that nobody here is smarter... we only use our brain in a different way..😑😑😑😑
and now just because of the stupid mistake you get a dislike for this video from me😢
I thought exactly the same. Paused the video for ten minutes and tried to find a solution where the first number is lower then 10 and the second bigger than 9.
I sat for 10 min looking at it with same problem, one ? And two ? Can easily solve but tried other ways because of the number of question marks.
Author is a real idiot. Wright "x+y", but NOT "?+??"!
Charmaine Rebello that's why somes have 150 IQ and other don't. Is it clear enough ?😂
I understood it within a few seconds. The first numbers in the totals are the differences and the last two numbers are the sums.
I found the solution easily, but what was very confusing is why the problem was expressed as ? + ?? = 123 and not ? + ? = 123. This seams to induct to a number of digits interpretation and I couldn't find a solution for 1D + 2D = 123 if D is equal to number of digits.
The givens are all in integer precision, so giving decimal results in the solution is invalid if we are to follow the pattern.
I found the rule, but I thought that the x had to have 1 digit and y had to have 2. This made me think that there was a different rule that works for the last one.
+Peter Roder same with me : / that confused the fuck out of me
+guldrev me too
And for the 2nd solution to your problem, no one thinks about it because it has decimals and negative numbers. The common answer is made of positive integers just like the other examples.
Does your question make sense after you put single "?" and double "?" that would lead people to think single digit and a double
two question marks imply a number > 9. misleading.
i got this one in 15 seconds...
me too, and I'm damn sure my IQ is nowhere near 150..
+Randomness Facebook does stuff like that to make people feel better about themselves. Your IQ fluctuates, and it doesn't fully determine how well you can solve real-life problems. The only thing it proves is that you're good at recognizing patterns, because that's what IQ tests are about. You'd need to solve maybe 20 problems of similar or greater difficulty very quickly to this to be considered 150+. And who knows, you might be selling yourself short; if you're great at puzzles then your IQ (which again is just your aptitude for solving puzzles) is pretty high.
+SuperMrPunch which is why taking a full IQ test is a great idea, as it gives you a more accurate idea of your IQ.
the trick here is to get us to SHARE on facebook. If you are a smart enough after you solve the problem you realise is just bait for email-fwding and facebook sharing
same im in 7th

That may be an alternative way to solve
? + ?? = 123
but it fails to follow the pattern of the others:
6 + 4 != 21 and 6 - 4 != 0
which means it's a totally separate problem on its own and there are further solutions, eg
x + y = 13 (the outer digits)
x - y = 2 (the inner digit(s))
which has the solution 7.5 + 5.5 =123
In fact it is possible to find polynomial functions of x and y which satisfy
f(x,y) = g(x) + h(y) = required value
for the given 8 examples, ie f(6,4) = 210, etc, and also solves f(?,??) = 123.
If h(y) is a linear function that goes through (0,0), ie h(0) = 0 and thus h(y) = ky, then to solve ? + ?? = 123 which also uses the same rule (polynomial function):
f(x,y) = 123
》g(x) + h(y) = 123
》ky = 123 - g(x)
》y = (123 - g(x))/k
And you'll be able to find an infinite number of solutions by plugging in x=0, 1, 2, 3, ... and finding the corresponding y. g(x) will be a polynomial of degree at least 6.
Infinitely more solutions can be found if f(x,y)=g(x)h(y), etc!
We can also execute it as
x+y=123
x-y=0
We will solve it and get to the answer that
x=61.5
y=61.5
so, 61.5+61.5=123
You dont need an high IQ to get this. He fool us to share the video so he can get alot of views and we show off in the comment section. 150 is incredibly high and is at another level. Just understanding that this is a trick to get views you should have a highIQ :)
lmao he only said that cus thats what the posts said
agreed, I paused the video when I saw the problem and then worked out the pattern in less than 20 seconds. I wouldn't say I'm an idiot but my IQ isn't 150.
he said it recquires an iq of 130...
No he definitely says 150
Tim White thats definitely too high...
where x equals an 8 ball of coke and p equals my paycheck I gambled away at the casino what is the relationship between my child support and time served?
max webster Agh! The dreaded "story problem."
Funniest thing I have read on You Tube. Well done

Ya so I went to the dealership today to buy a Hummer but i only had $20 in my pocket and so I stopped to see a lot lizard 4 a blow job and missed a potential $60k opportunity cost. Afterwards I went to my realtor to make an offer on the Playboy Mansion with my $59, 980 "opportunity" money as a down payment. People need to get off this fucking shit where other people tell them what to do with their lives and $ cause they're too dumb to think for themselves and pay off their credit cards, cars and child support by using their brains.
umm... 7? I think
okay, x=8, p=paycheck over casino. child support=$p/x, time=p/child support=p. there for your relationship between child support and time served is (p/x)/p=x=8.
Its easy : the first digit is the difference, the last digits are the sum
It could be 12 and 11
if your argument on (x)^x^x^x......=2
x=(2)^1\2 is correct then x+x+x+x+x+x.........=2
x=0
isn't that a little buggy ?
Makes 1x ? + 2x ?? ... i thought that would mean single digit / double digit ... Well now that fked me over ... thanks >.>
me too :/
Got this one in maybe 20 seconds, whereas many of the others baffle me. As for an IQ of 150, I doubt that can be ascertained by completing one test question. My IQ, when tested way back in the early seventies was 132, so no-where near 150.
Wasn't it 123?
@@xXJ4FARGAMERXx he’s talking about his iq
Well, as the test was intended to identify the 80-90 range.
a.k.a Those who can keep up with the general public, with a little it of extra help. (so, lets make sure they get it)
those numbers aren't that reliable:
the purpose has somewhat shifted nowadays (to bragging-rights mostly) but is still notably less reliable the further you get from 100.
'132 in the 70s', yeah no.
'around 130' is an outcome you could get in the 70s
even those who specialise in exactly this (the 'high end'), held 'around 145' as the end of reliablity in the 2000s
(I don't think they've gone a lot further since)
Hey does this work as well,
so basically what i did is . 6+4 = 210
so i assume that 10 = 210
so if we 1 = 21 .
so let's take half everything. 3+2 = 105
so here it becomes 63+ 42 =105
so if we just add decimals to any of the following 3 or 2 . then
okay so if we just add some decimals to either then
3.85714285714 + 2 = 123.
now just multiply each with 21.
It was such an easy question and nearly one of the few questions that I can solve on this channel
Wasn't sure why you used different numbers of question marks to represent the two numbers. I thought it was a bit misleading in that one could interpret each question mark as an individual digit, which yields no solution for your problem with that constraint.
+Cow Norris I must admit I got caught up in this trap as well. I think it would have been better if pronumerals were used.
I got this in like 5 seconds. I highly doubt that it'd be that easy to achieve a genius IQ in 5 seconds. I also doubt that I'm a genius.
I also got a different answer than him, even though both are correct. My answer was 7.5 and 4.5.
+Dean Yona
is 7.5, -4.5 (negative) so that
7.5 - (-4.5) = 12
7.5 + (-4.5) = 3
final result is
"12"++"3" = "123"
12, 11gives you
"1"++"23" = "123"
++ stands for concatenation.
yeah I'm honestly disappointed... i clicked on the thumbnail because i had no idea and then once i saw all the numbers it was my second guess. I realized right as he was saying "genius IQ"
When I looked at it for the first time, I didn't understand it but then i took a closer look at it and the answer was hidden within very well!
I get 11 and 12 assuming the single and double question marks only represent two distinct integers and not a single sigit and two digit integers.
Thank you for this video test. It was challenging and enlightening. Initially, I was able to see how the solutions to the problems were derived and performed trial and error for the 12+11=123. Once you showed the formula progression, I used that to solve the second solution of =123, sort of. I used 4.5 instead of -4.5 since the total solution involved, in my mind, two separate computations; one using subtraction to append that solution to a separate solution that used addition. However, I do like single formulas that capture a whole solution and will try to apply that reasoning to future problems. Thanks again.
that was seriously easy, maybe my mind just works weirdly
+Xander Michels nope, it's easy an predictable.
fairs
No, it doesn't.
I'm weird. I looked at this and knew it instantly
Sarcasm much -_-
The single and double question marks threw me off. I thought it was a single digit number and a two digit number. Was it intentional?
I'm pretty young and I understood this, so I'm smart?
This is how it works. You subtract the first number of the equation with the second number of the equation, say it was 4 + 3 it would be 1, 1 is the first digit of the number, next you add 4 and 3 together in place value, and you get 7, the answer would be 17.
every normal person solves this in a second or two
+intersanctum yepers too easy lol
every normal person with a 5th grade level of education in maths, tbf.
every stupid man would say that
hell nooo say what that this shite is easy? This is for kids.
Didn't know that linear algebra makes you a genius
+Joe Harrison For social networks people it does, apparently...
+Joe Harrison no you have some level of lateral thinking though.
+00Billy Yes, but a person that is not familiar with complex math can still have a high IQ.
+Indomitable but that isn't complex math. That's something you can figure out without any knowledge of math as long as you know substraction and addition. In fact I know math but I solved this in a very intuitive way without actually using linear algebra.
+Indomitable This type of linear systems is taught in highschool..
a + b = 123 -> a-b = 1 and a+b = 23 -> solving equations give a=12 and b = 11
Can I say that I knew how to get to the answer and I understood the logic, but I thought one questionmark means one number and two questionmarks mean two numbers and that this confused me?
The question marks were off putting as I saw one question mark and tried to think of a single digit number
understanding this does not make you a genius, sorry. I know I'm not a genius, but I got it on a few seconds. And trust me, I'm an idiot
What puzzled me was that the first number has one question mark and the second has two. I only found one solution (12+11=123) because I dismissed 12 and 3, assuming they had to be integers. And you do have to make assumptions, because all you have is some enables. Otherwise the rule might as well be that the third number just has to have no more digits than the first two numbers together, in which case everyone forgot about thousands more solutions. So my assumption was that since in all examples there were integers so that you join the difference and the sum, that would be the rule. By that rule the ONLY solution is what I found.
I'm inclined to believe that the real answer should be the first one you show since in the original post there are only natural numbers + other natural numbers= natural number, no negative or rational numbers. Maybe I'm just saying it because it's the answer that I found but I think the point that I made remains valid.
man the number of questions marks i the problem threw me off completely, like how is aone didig number - a two digit number supposed to equal 1 or 12,
I literally saw this and got the answer within 3 seconds
When I first came across this puzzle, the statement was "If 6 + 4 =210 , then ? + ? ? =123"
that was the only information I got. So I think "+" , " = " and "?" are symbols of variable and "+" does not represent any mathematical operation. I would suggest the answer could be
like these 6+4=210 implies 6 "5" 4 "3" 2 1 0 and ? + ? ? = 1 2 3 represents
"6" "7" "8" "9" "0" 1 2 3. They are like numerical series.
You add the first two to get the last two then subtract to get the first two. It's kinda like a mathematic poem. Im probably wrong but.. like 15+3=18 15-3 is 12. Therego 1218 is the responce it is asking for
My first guess at the pattern was correct. My conclusion is that solving this test does not imply an IQ of 150.
Your challenges are great but the tricky think that you did and was miss leading that in the solution you have two digit numbers and you show ?+??=123, its should be either ?+?=123 or ??+??=123 to be correct!
he wanted to show that the two numbers where different from each other but it was a mistake to use question marks as an indicator of that. i also thought that the second number should have been a two digit one
Totally agree with that. there isn't a solution for a one digit x or y
The only reason I couldn't solve the new problem is that I thought you meant the solution to be a 1 digit number plus a 2 digit number equals 123, but I did understand what was going on
The question marks seemed indicative of the number of digits.
I figured it out in less than 10 seconds. First thing I thought was what they really add up to. Then I looked ah the end of the numbers and I was like 😑😑
And the first digit of the result is a-b
And the first digit of the result is a-b
E.g.
6-4=2
6+4=10
210
12+11=123
I thought the number of question marks represented the number of digits each number must have...
same here
I am not that good with math, or life for that matter lol, but the fact I came up with this solution really made my evening. I keep up with this channel but this is definitely the first puzzle I got all on my own :)
Isse asaan sawal maine zindegi me nehi dekhe,aapke channel se aysi ummed nehi thi
Btw 61.5 61.5 also is a valid solution
61.5 - 61.5 = 0
61.5 + 61.5 = 123
that makes
0|123 -> 123
Also 61.5 and -61.5
Well, I guess it depends on the rule of how you append the numbers.
