Do you have a bot that comments on every video every so often?
if they can upload the video y they cant copy paste the comment?
YOU ARE NOT SUPPOSED TO USE ROOTS AS IT IS USING DIGIT 2 AND RULE IS ONLY 4 AND NO OTHER DIGIT. HE IS CONFUSED.
Scam School sruare roots mean you raise 4^1/2 power and thats against the rules.this video is fail
I only got to 13, but I didn't use a single square root....
5, 6 and 7 are interesting... because x! / x = x-1! you can do:
4! / 4 - 4 / 4 = 24 / 4 - 1= 6 - 1 = 5
4! / 4 - 4 + 4 = 24 / 4 - 0 = 6
4! / 4 + 4 / 4 = 24 / 4 + 1 = 6 + 1 = 7
I did 9-12 with factorials as well....
Am i the only one who noticed the clock in the upper right hand corner? start watching it at 6:20 in the video.. watch it for 20 seconds... tell me if I'm crazy...
Wow you're right, it went forward instead of backwards
Wow what hacksource
+Niall Hannagen You are right. It counts down until he says, “You just changed the order of what I said, alright 8 go!” czcams.com/video/gDulLVBtNkk/video.htmlm26s The he does a crazy fiendish laugh, and It starts counting up for another 24 seconds until he says, “Ooh, now it’s getting hard.” There is a cut scene, and the timer is back to counting DOWN at 3m50s instead of counting UP at 8m24s czcams.com/video/gDulLVBtNkk/video.htmlm03s. I think we may have been scammed.
Woah never noticed first time
Briaaaaaaaaann
"It's astonishingly similar"
"It's totally different"
C O N S I S I T A N T
"16. It's 4 x 4 + 4 - 4" Ooorr 4 + 4 + 4 + 4. xD
+Silver Tongue yeah, we got so caught up in fancy moves we missed the obvious.
+Scam School it happens. I think that's a big point of a lot of your Videos, isn't it? People get into this mindset where they try these complicated answers, when it's actually pretty easy.
+Scam School How about 14 XD 4+4+4+sq.route 4= 14...
+Hunter Wimsatt and how abot 12=4+4+sq.root of 4+sq. root of 4
I went complicated for 6 LMAO 4! / 4 + (4 - 4) because 4! is 24 and 24 / 4 is 6 and 6 + 0 is 6 ..
Did anyone else notice the timer start going up from 6:31-7:06
Me
I was so confused
me
no wait no it from 8:00:00 - 8:24:00
*8:20 - 8:24 then skipped over to 3:28 or 48 or 38
I did this in my free time for months after seeing this video, and I finally gave up at 379, which I'm fairly certain is impossible, at least with the knowledge that I possess. I learned about subfactorials specifically for this and it came in very handy.
4! / √√√(.4^(4!)) + 4 = 379
Did you ever keep going?
i like how the timer started counting up sometimes like at 8 minutes ( 6:30 )
Lol
Brian, I believe in equal oppertunity... I get drunk before watching Scam School
I like how Brushwood is just shouting out answers as he thinks of them for this one.
I got to 863, but i got bored and stopped 6 minutes early
I know right: 863 = (subfactorial(4))!!-subfactorial(exp(-ln(√(4%))))-subfactorial(exp(-ln(√(4%))))+Gamma(4)
(Check WolframAlpha.com if you don't believe me)
A. Z. no letters (not even greek)
Adrian Munteanu Well, thats what Brain say but the conventional version of the puzzel says nothing about letters.
The timer is all wrong.
7:00 timer is going up
7:20 timer is going down
Sometimes the time goes backwards for no reason.
pls scamschool
thats why the show is called SCAM school
Shocking how temporary patterns bias our thinking... 16 = 4+4+4+4. I fell into the trap, btw. I first came up with (sqrt(4^4)) - (4-4), or sqrt(256) - 0, which reduces to 16 - 0 = 16. We all fall victim to temporary pattern bias when we're asked to solve any series of difficult problems: because we accustom ourselves to a pattern of not relying on a simple answer, we're sometimes prone to missing the most obvious answer! However, a variant of the above pattern helped me solve for 15 and 17, respectively (so it has some use):
15 = (sqrt(4^4)) - (4/4)
17 = (sqrt(4^4)) + (4/4)
Here's two more absurd ones for 16:
16 = ((4+4)/4)^4, or 2^4
16 = 4^((4+4)/4), or 4^2
For good measure: 21.
21 = 4! - 4 + (4/4)
And last (but not least), a legitimate 19:
19 = 4! - 4 - (4/4)
"You unmathed!" 😂😂
Despite years of math experience, I suck at challenges like these. I completed 0-9, got to 10, and just blanked out. But I also was not using square roots simply because, in the back of my mind, I know there's an invisible 2 in there, so it didn't seem fair:
4+4-4-4 = 0
(4+4)/(4+4) = 1
4/4 + 4/4 = 2
(4+4+4)/4 = 3
4(4-4) +4 = 4
4! / 4 - 4/4 = 5
(4+4)/4 + 4 = 6
4! / 4 + 4/4 = 7
4*4 - 4 - 4 = 8
(4! - 1)/4 + 4 = 9
Oh well.
+nychold the 9 is wrong
+fralfa95 I typed it wrong. It's supposed to be (4! - 4)/4 + 4, which is 9:
4! = 24
24 - 4 = 20
20 / 4 = 5
5 + 4 = 9
good
+nychold what is 4!
diogo mamano 4! is the factorial of four i.e. 1*2*3*4=24
Okay but everyone's thinking so hard. Like, 8= 4+4+4-4
yeah I notice this to. Making it little to complicated than it should be
Right that's what I said
And for 14 they could have done 4+4+4+square root 4 instead of 4!/sr4+4/sr4
DareToBeDom I don't think they're looking at the simple solutions because they're putting most of their math power on it and I guess wouldn't even think of simple solutions?
I know, it just bugs me XD
How can you use sqrt? It's the inverse of sqr, essentially your rules excluded the 2 in that, which means no sqrt, which is x to the power 1/2.
+Lympy Downunder yeah, but by that logic, each 4 used is actually just 4*1, which would be illegal since it "adds" a 1.
not really, see a sqrt is a symbol defining power 1/2, it doesn't equal the same, it IS the same.
+Scam School Uh oh, he's right. If you can't use a cubed root, which is raising a number to the 1/3 power, why would raising to the 1/2 being allowed? Because 4 is a perfect square? Cool puzzle none the less!
+Lympy Downunder By the same logic you couldn't use 4! which is 4x3x2x1 - the root symbol is a defined mathematical symbol and for this puzzle all mathematical symbols are valid - Pi, e and log included (though I guess you could argue if you could use log for log base 10 or whether you had to define what base to log is (but unless specified I would always assume that it's base 10 for the log)
CaptinFonz You're just making up rules bro. If all mathematic symbols are allowed, then I can just use x, where x = the number. Or for example I could say root i times root i +4 = 5 which is bordering on making this puzzle a peace of piss.
I got eight.
>->
Fuck off, I'm tired.
...
I feel like I would have gotten a lot further in the time limit if I knew square roots were fair game. I'm so used to seeing them as a power of 1/2 that I didn't even realize they were allowed.
Yeah, I got up to 10 without them then started using them.
I got really mad when I saw them using it. I couldn't get past like 6 without them
Same!
draconitious well ! Is by that logic also not fair and that makes game very boring since u use +,-,×,÷,(,) ..
Only went up to "=9" so far, and it's pretty easy. It's pretty fun though... a puzzle that just keeps on giving.
"Can you get eight?" * tells them the answer *
gahhhh what's the point in challenging them if you're either helping them or just giving them the answer every time? I know you're drunk, but come onnnn
70,000 views and no one wants to share how dumb they are/aren't. I didn't even try. Internet + Math = NoGo.
I got to 72 after a few hours, but the internet has yet to find me a solution for 73 without double factorial or gamma so i think i did all there is possible
hahaha
SmileyMPV (4! nCr √4) / 4+4
4!!/.4 + [√(4!!·4!)]
12treeGoldfisher
that would tae like 10 minutes to think of by its self...
12treeGoldfisher There can't be infinite solutions because there's a finite number of 4s and a finite number of manipulations you can make on them...
That is cool! I really like that puzzle
Wow, dudes got so much better since last time XD
why did they calculate 4x4+4-4=16 and not just 4+4+4+4=16
because dumb.
because sometimes dumb people can see what smart people cant 0.0 simple minded
Because YOLO
Because their mind is very mathematical and complicated, so they think complex, not easily
Because they don't think math, but logic. With 4 fours, we have a number of "sets" that we arrange on our convenience. I want to get close to the answer the fastest possible (rushing on time) then I use my sets to compensate. I know that if I need a ±1, I use 4/4, if I need 0 I use +4-4 etc...
4+4+4+4=16 idk what was up with their solution but that's the easiest one to get!
+Neel Parmar yeah, we were too in the zone to think straight.
+Scam School And its even alot easier if you use 4^0 wich is 1, i got to 28 in 10 minutes used it in 22 of the answers :D. Try it youll find it alot simpler :D
That is such an easy answer!! ; -)
+Ricardo Oliveira You can't write any other numbers, so that doesn't work.
+Ricardo Oliveira you're not allowed to use 4^0 (unless you write it as 4^(4-4)
I love this puzzle so much.
There was actually a paper written about it, and how to solve the ENTIRE NATURAL SET.
I only remember the answer, but not how to explain it! XD
You take the Log, base the square root of four over four, of: The Log of the square root of four over four.
Numberphile did a great video on it. ^^
I've never heard someone so happy to square root before.
I made it to 10985, and I'm only 3.
sKebess yeah, right
Jon_BL You're just jealous.
if you were 3 years old, you wouldn't have a CZcams account :P Yeah, I know stuff.
No you were three. By the time you finished you were 42.
lol I get ur joke .... Let them keep wondering
I didn't choose the math game. The math game chose me.
lol
I would like to point out to those that are saying that square root and factorial don't work because they are implicitly adding numbers, he said that you can't draw new numbers, not imply hat numbers are there.
alexvanawesome Hey, professor! Why don't you get over here and finish drinking your beer!
7:00 -Timer is going up, (Stopwatch)
7:20- Timer is going down,(Timer)
Dat boodi in the background 3:35
Maybe Baby .. i was sure someone was mentioning this... i searched for "3:3" :))))
Damn xd
I've seen a LOT better.
For 14, you could've just put 4+4+4+√4=14
Had this for homework

Hmm, just curious but doesn't 4! and the square root kind of break the rules?
4! = 4 * 3 * 2 * 1, you just packaged up in a nice little '!'
sqrt(4) is "what TWO numbers = this number" we just defaulty define sqrt to be 2.
Also, 4^2 is legit as it is technically 4*4. I mean, if you're going to allow 4! then 4^2 should be allowed too.
I know I'm being a negative nancy here, but the rules seem to randomly dictate what's allowed and what isn't. Was this just the rules decided on to make it easiest to generate all the numbers needed? I suppose a proof was done to determine if it's possible to get all ints up to a certain number.
***** Yea, I figured it may be that simple. Logic be damned. Just be sure you only see 4 4's and it's all good :)
4! helped for larger numbers around 20, but also for numbers around 12
I found aPDF on Google called "The Definitive Four Fours Answer Key" where someone worked out answers up to and including 40000. He also explains each maths symbol he uses.
".(root4)" seems like cheating...
At 8 minutes the clock stops going down and starts going up. Bet you didn't see that
David McConnell sharp eye.
Scam School was that on purpose?
David McConnell nah. Editing error I missed.
Scam School interesting video anyways. Love from the UK!!!! Keep up the great work
Scam School Hiiiii
I had to do this for math and I just thought back to this video
i got till 11...maan...that was some freaking brain exercise.....i sure think that it needs some real talent to crack 20 in 10mins.....And u did good Brian...u've got some real talents, i should give you that....!!!
+Noble Saji thanks!
no...i'm serious man, u guys did great....i can't wait to pull this riddle over at school....i'm in 12th ...we've learned all these stuff....so..Thank You
why did the timer go up and then down
.(√4) really?
that's what i thought... pretty stoopid... 🤔🤔
+Bob Gomez just use 4!-4-4/4
Scam school
Wouldn't it be √(.4) and if so, wouldn't that throw off the equation they used which would not equal 19? Also isn’t .4 written as 0.4?
Their 19 is incorrect. 4 over √(.4) would = 1/5 per their math and 1/5 + 1 is NOT 19
As we learn in Calculus 1, the limit as x goes to 4 of (x/0) goes to infinity therefore to put four 4's in the equation you can do lim x>>>4 of x/(x-4) replace x with 4 and you get (4/4-4) which is 4/0 which is infinity. Although it takes all the fun out of this game, you can solve for infinity in 5 seconds out of the 10 minutes given.
Nailed the first one!
I'm dying😂😂😂
Not in the time but i managed to get first 100 then stopped. 31 was one of the most difficult. Here's how i did it :
((4 +sqroot(4))! + 4! ) / 4!
= ((4+2)! + 24 )/ 24
= (6! + 24)/24
= (720 + 24)/24
=744/24
=31
Wow that is so cool!!!! I got stuck on 31 and scrolled down to see if anyone had an answer and sure enough!!! That's the most awesome answer wow. You must have figured it out by realizing 6! is 30 times greater than 4! and then seeing that adding one more 4! before dividing it all by 4! would get 31? That's totally genius. I just did a little more searching and also found this one: 4! + (4! + 4)/4. Kicking myself for not coming up with it lol >:(
it has to be with four fours...not that! 4!+(4!+4)/4 is right!!!
What you on about. I did use 4 fours
Bjwphneb You can only use 4 4s and cannot add any other number so that problem answer broke the rules. you used a 6 and a 5th 4
Alex Tzvetkov Your answer is 30 not 31, but sure enough u probably got 30
on 16, why didn't they just do 4+4+4+4? it would save them some time
***** yeah. brainfart.
I was thinking the same for 19, easiest would have been 4! - 4 -4/4
Arkitekt26 yeah cause that's just as easy.
Using logarithms, you can produce any number(+ve integer) using four 4s.
Funny how just 4 numbers could creat such a fun and challenging puzzle
why does the timer go down to 8:00 and then start counting up???
+Alvaro Ampudia editing error
The world may never know
+Alvaro Ampudia Illuminati is tampering with it.
cool ccam school replied!
+Alvaro Ampudia i noticed that too
if there is allready music playing in the bar, you should not put your own background music behind the video. great video anyway! ;)
When he said ''equals every natural number'' I thought diving by zero lol
It’s possible to make any number with 4 4s, logarithms, and square roots
1=logsqrt(4)/4(log4(sqrt(4))
2=logsqrt(4)/4(log4(sqrt(sqrt(4)))
3=logsqrt(4)/4(log4(sqrt(sqrt(sqrt(4))))
etc.
but but... 4+4+4+ square root of 4 = 14 too... it was so much simpler... right?
true. he says there are pages and hundreds of solutions too. so you can make it much more complex and long and still get to the answer
I got only to 10, but I did not use square roots.
impressive!
Brian Brushwood Surely square roots are cheating as a square root SHOULD have a 2 on it just like cube root and quad root
How did you get 3? :O
Ahimtar HoN
(4+4+4)/4 = 3
I came across this puzzle at school 50 years ago except that it was to use 4 x 2 (not 4 x 4).
(Technically that's more difficult because Sqrt 4 = 2 but one cannot get from 2 to 4 without using 2 x 2)
The challenge was to make every number from 1 -100 with 4 x 2.
I cannot remember how far we got as school kids (but I recall we did get a lot of the numbers)
Then a few years ago I posted this puzzle in the MENSA ( High IQ Society) magazine and got several solutions for every number from 1-100. Some were very elegant and some were very clumsy, but it is definitely possible to generate every number from 1- 100 in one way or another.
Some of the solutions used more obscure operators like MOD ( = integer part of a fraction : thus MOD 23.75 = 23) and FRAC (= fractional part of a fraction : thus FRAC 23.75 = 0.75) . And some solutions used trigonometric functions e.g. Cos, Sin, Tan etc, also inverse trig functions ( ArcCos, ArcSin etc) as well as Ln and e ^ x .
Finally it became clear that one could generate almost ANY number using a suitable combination of obscure operators and functions , so it became rather boring to go beyond 100.
However, this remains a very interesting puzzle ,and great fun to see how far one can get by using only the simple operators : + , - , x, / , sqrt, !
____________
ScamSchool addicts might be interested to try to generate 24 using only 1,3,4,6 once (and ONCE only) and ONLY the four basic operators : + , - , x , / .
If you can solve that : try it with 5 5 5 1 (once and ONCE only) under the same rules
______________
PS : Thanks to Brian and Diamond Jim for this amazing CZcams series - endless fun ! :-))))
dang you guys are good at math ahha
I don't think .√4 is an actual number (.2), so bit of a cheat there. 4! - 4 - 4/4) would have worked for 19 though.
Are you trying to say √4 = 0.2? Considering √4 = 2. Not trying to seem like a jerk, I'm just trying to understand what you are saying better. :)
MrSmashyourWindow No, I think you missed the period right before the "√4". So, what I'm saying is that ".√4" (with period) does not evaluate to ".2" - which is part of a solution to reach 19 that features in the video.
Jaap van der Velde Oh, sorry I didn't notice that. Well either way, good job on figuring that out. :)
Jaap van der Velde
But YOU on the other hand missed the brackets in the puzzle. They said 4/.(√4) - 4/4. In other words, 4/.2 - 4/4
***** But still that isn't a legit move. You can't write a number using functions to define the digits. (3-2).(3!-√4) is not a way to write 1.4.
I know a simple solution to *EVERY* 4 4's problem: (4-4)/(4-4).
You should do some more card tricks so I can do trickery on my classmates
I got 39. And only stopped there because I couldn't write fast enough. They definitely should have focused less on solving each equation individually, and more on using the equations of 1 (4/4) ,2 (sq rt 4) , 3 (4/4 + sq rt 4), and 4 (well... 4) as base points to solve the rest. That way you can use 4 numbers (or equations of four numbers) to make any number instead of just "4"
People at home can just google it!
For fourteen all I did was 4+4+4+ the square route of 4,
They made me feel like what I did was way to simple... 😂😂😂🤓🤓🤓
Used a lot more factorials than square roots. even considered log base 4 of 4
Got to 37 in 10 minutes. Harder than I expected
I'm not got at math but for 16 you can do 4+4+4+4=16 right
Havok hellraiser yeah. we were dumb on that one.
Scam School And for the 8: 4+4+4-4 ;)
Scam School hi brian
It's easy if you use SQUARE root, you should use the fourth root, you don't write number 2 but you use a 2 as a root with four fours (and you said that only the four fours are allowed!), with that much loose interpretation getting the power of two should also be allowed, or else just try without square and do fourth root, it's more of a challenge that way.
no because when you use sqaure root the number 2 isnt showed it is just there like 4 is 4/1 but we dont write 4/1 we just write 4
That is nonsense, 4/1 is not supposed to be written (only for children as explanation for multiplying or adding up fractions), on the other hand the square root is not written by a convention, but it exists non the less!!! Your way is too easy and feels like cheating if you say to use just four fours and then use a square root. Use a square root created by some of the four fours, like ((4+4)/4)root of 4. The channel isn't called "scam school" for nothing, I guess...
no its really none existing we dont write it as we suppose its there
whatever, suppose what you want, it's your right, but the rules should be clarified.
My mentor on my PhD studies would have flunked me easily if I would try anything of this sort without clarifying the rules.
Djordje Petrovic ur dump.. what is said is right we dont write 4/1 we write 4
Got it for every number!
Suppose you want to make answer 'x'.
Formula
[log(log(4^(4^x)))-log(log(4))]/log(4)
Just vary x from 1 to ∞ ;)
At around 6:38, they put 4 squared times 2 plus 4 squared times 2 equals 8. 4 squared equals 2. 2 times 4 equals 8. They have that twice added. 8 plus 8 equals 16 though. They needed to put the square root over the entire part of 4 times 4, not just one of the 4s
I wrote a program to do this automatically for me. Do I win all the beers?
Edit: The program is below in this thread. I slapped it together so don't judge me *put on tinfoil hat
I'm really interested in Computer Science. If you really did write a program to do this I'd love to see your source code. :)
bennyty I could, but part of computer science/ software engineering is learning to develop algorithms for problems such as this. Try telling me as an explanation how you would tackle this logically. I'll show you my source code after.
I would try to teach the computer as many "base" number combinations as possible (such as sqrt(4)=2 and 4!=24) and have the computer guess and check combinations while keeping a running total of how many fours it had used so far.
I'm sure this wouldn't be *anywhere* near the most efficient way compute such a problem but I'm fairly young with no real schooling in advanced number theory or computation.
Alright, well. This is relatively complex to compute and requires a ton of conditions to check against. (I'm basically brute forcing it, too lazy to seek out a more efficient algorithm). Give me some time to rewrite the code. If your new to coding I'll need to dumb it down b/c I used some more advanced coding techniques. Unfortunately, I'm busy writing a research paper tonight. I'll post the revised code Tuesday most likely.
bennyty *WARNING* large amounts of text below.
Here's the results from the program I ran. I let it try and find 10000 combinations. It looks like after 32 it becomes impossible to get certain values but regardless, for fun, I let it run to 10k. Here's the source code. It's not perfect but it works.
drive.google.com/file/d/0B_TApZSRG98mWDdkSUZvS0xjZjg/edit?usp=sharing
Note* It does not show the placement of the parens, you have to figure out what order it did the math. Sorry, was too lazy to program that in and I slapped the code together so it's not exactly elegant hehe. I'll paste the source code in another reply in case someone is too paranoid that it's a virus or something or doesn't know how to view it(if that's an issue, you won't understand it anyways). Also, this was a lot more complicated than I originally anticipated. If you aren't sure how something works just ask. I put comments through out but I didn't comment everything.

only a true nerd's first reaction to 9 is (4 - 4/4)^√4 :P
Log base√4/4 of (log₄√4)=1 then added a square root for what ever number you want. Log base√4/4 of (log₄√√4)=2 Log base√4/4 of (log₄√√√√√4)=5 etc.
I like brians laugh
why can you square root and not cubed root?
Because that would require using a 3 in the notation.
Justin Davis but squaring technically has a 2 in it.
lehman Square Roots...
***** what?
Cube roots require adding a 3, while square roots have a symbol that replaces the 2
Sorry, have to call you on this one. I don't think ". sqrt(2)" (using the decimal point to mean "a tenth of", where it's in front of an operation) is legit. "." is not an operator (or an operation). It's a decimal point, and it only has meaning when it's in, and part of, a written-out number.
Angi Long Lucky for me I'm the one buying the beers, and thus get to make the rules!
Scam School That just makes you a cheater. :P
Tell you what. I've got my MS in math. If you can find someone more highly -- or even more recently (mine was 1998) -- educated in math who agrees with you, then decimal-points-as-operators as you used one here can be officially allowed in this game. Alternatively, you could find a computer programming language or spreadsheet language or something like that -- something already in existence, not a new one written for the purpose -- that uses decimal points in this way. Deal?
Angi Long Just when you think teachers can't fuck up anything else fun, they always manage a way ;)
Chris N. Productions *blink* Really? Are you talking about me? Because first, not a teacher. Not as a profession, anyway. And I thought I was making it fun, presenting a challenge. Certainly seems to me like something that Brian would go for, anyway.
This game/puzzle is pointless if people are allowed to make up their own operators while solving it. Otherwise, you could just make up an operator that has your goal number as its only output, and use that for every single formula. The challenge is to do it legitimately, with only existing, known operators. Right?
The rules were you can't add new numbers. So no squaring or cubing. They never said anything about operators.
Attention to detail.
Guinness book world record for the amount of word "4" got said in the video. :)))
Those primes are the real tricksters.
he said u cant use any number other than 4. Square root of a number is 1/2 to the power of the number. so your solutions are wrong if you use square roots
Nahome Babry that's silly. That's like saying you can't write the number four, since it's equivalent to writing 4*1.
its not silly. the rules are not clear enough... for example u used point four, which uses the number zero..... imagine if u were taking a maths exam, u cant write .4, you have to write it as 0.4.
Nahome Babry relevant: czcams.com/video/pWdd6_ZxX8c/video.html
the guy in the video is not you, so i don't believe it
Scam School again, .4 =4/10 grade school math. i rate this game 4/10
I did it without using any roots and came till 9
0=4-4+4-4
1=4/4+4-4
2=4/4+4/4
3=(4+4+4)/4
4=(4/4)^4*4
5=(4/4)^4+4
6=(4+4)/4+4
7=4!/4+4/4
8=(4*4)/4+4
9=4+4+4/4
Using the root makes it too easy, don't you think...
ten without the root is a tough one...
not understanding 6, doesnt that equation equal 1?
Miranda Moloney nope. It's four plus four (8), divided by four (2), plus four (6)
oh yeah
No it equals nine cause of order of operations. You do the division first and if it's 4+4/4+4, then it would become 4+1+4 which equals 9
jtc355 there are brackets around 4+4
(4+4)/4+4 = 6
too much work 😂
We did this in my Algebra class with integers from 1-20.
Why does the timer start counting up at 6:27 ?
+Andrew Balsiger editing error. Good catch.
+Andrew Balsiger yeah I saw that
+Scam School why didnt you reply to me?????
It got to 8 mins from 10 then started counting up... Bad editing
Oh man I'm in 8th grade. What does multiply mean? I'm from Kentucky btw, not the US.
***** ...
***** You sir, are an idiot.
***** ...which Kentucky are you from sir?
***** times, product, opposite of divide in a way
Bhaarath Rapture I was joking.
I did this at school (7th grade) and I got around 300 different numbers! I still am finding numbers! Ive been working on it for 7 months!! So hard!
this was fun, done in like 3 mins though =D once i did 3 the rest of them was easy =D
using square root isnot fair
I agree, it is similar to cube rooting and so on 👍🙃
Exactly! I got to 9, without square root.. Could have easily beaten 20 with it.. Or even (. 4) which is 0.4... No fair
a radical does not have a physical 4, so it fits in with the rules
still..
I think that the challenge is basically to use universally accepted symbols that math professors and teachers and other people and text books would know about that does not show a number when written down to make four 4's somehow into any integer. So for square root you can show that as a universally accept symbol without adding a number when writing you can show it like this √ as you see this could be shown as ^(1/2) but it can be written without a writing a number and it is universally accepted by math teachers, professors, people and it is shown that way in many text books.
Their answer for 19 was: 4/.(√4)-4/4=19
I don't get it, someone can explain to me?
P.D. My answer was: 4!-4-4/4=19
.(sqrt4) =.2
4/.2 = 20
20 - 4/4 = 19
Erik Zandbergen Ok, I get it now, it is a decimal 0.√4. I suppose this is allowed in the rules. Thank a lot Erik.
Rojo I don't get yours actually.
4! = 10
4/4 = 1
10-4-1 = 5
???
I used (√4)!+4x(√4+√4)+...
√4 = 2
2! = 3
2 + 2 = 4
3+4x4 = 19
Nemo's Channel
4! = 4*3*2*1 =24
24-4-1=19
Fidel Salas yeah, I was confusing it with + instead of *, that's how I got 4! = 10.
I was super proud that i did 0 to 9 without using square roots at all. And missed the part where you're supposed to just keep going for the 10 minutes worth.
12 problems. Not even mad. 3 brains vs my own. I did really good for not having 3 brains constantly working on different solutions.
(4-4)/(4-4)=0/0=0,1,2,3,4,........
0/0= infinity
+Kushagra Nishee or undefined
+Dragos D yup mate
that's called infinite or undefined because it has infinite number of solutions meaning it can satisfy any values
Ha smart
is it legal to join numbers like 44
I'd say yes.
I got to 100 in about 9:30 minutes.
+Hawaii Klratz right💩
+Klratz than how do you get 100 out of it
+Klratz nerd
Wow. My math class did this.
+Philip Strömer On #8, the solution is not
(sqrt4) X4 + (sqrt4) X4 Though the video does makes it look that way.
What they meant was (sqrt4X4)+(sqrt4X4) = (sqrt16) + (sqrt16) = (4) + (4) = 8
i couldn't do much of these at all since im only a 6th grader. :\
I am in 6th grade and figured out these.
BTW if I say _/ it is the sq rt.
4*4-4*4=0
(4*4)/(4*4)=1
(4*4)/(4*_/4)=2
((4*4)-4)/4=3
(_/4*_/4)+4-4=4
((4^_/4)+4)/4=5
To name a few
Noob you just copied them
The Noob Enforcer you just copied them idiot
I'm in fifth grade and d I got 18
ethan O'Connor no you didnt... shut the hell up... jk that was mean, but in all seriousness, idoubt you got past 4
at 6:30 .. the time goes up from counting down to 8 minutes .. wtf?
I would try this but I can't do math except for add subtract and a tiny bit of multiplication
I wanted to try this but I am awake at 2:26 am at my grandmas
!
