There are 15 Matchstick Puzzles (fix the equation) presented in this video, Give it a try before checking the solution. Comment if you found an alternate solution.
in all the puzzles you can move 1 stick to go diagonally over the = which makes the math sign for "doesn't equal" and this solves all 15 puzzles
1: 3+6=9, 12: 0+0=0, there are some others where the equation is transposed or a different match can be moved to give the answer.
The first one could be 3+6=9
But that doesn't "fix the equation", it turns it into an equality.
Inequality =/= equation.

12th could be 0 + 0 = 0
It can also be 0+6=6
6th one could be 7 - 2 = 5
Puzzle 1. Move the same matchstick to form the second number to a 6. 3+6 = 9
I made it 3+5=8
puzzle 2 you can move a match from the + to the 4 to make a 9 (9-6=3)
got the same
me too
@@slycat123123that works, but I think the nine needs to have a line at the bottom
Problem 2 alternate: take the vertical match in the plus sign to make the 4 a 9. 9-6=3. Update: see comment by @AzureKyle below.
Problem 6 alternate: take the vertical match in the plus sign to make the 1 a 7. 7-2=5.
Problem 12 alternate: take the middle horizontal in the 6 to make that 6 a 0. 0+0=0.
Problem 14 alternate: 6 + 1 = 7
There's an issue with your Problem 2 alternate. In these puzzles, 9 has a match on the bottom. It's not just a line with a circle, it's a line with a circle and a line underneath, so you can't turn 4 into a 9 by moving one match.
@@AzureKyle You are correct. I forgot about that.
@@maddogfargo3153 also 6 - 7 = -1
#14 alternate 6 - 7 = -1
#14 : from 6+ 7 = 1 ---> 6 +1=7
also: 6 - 7 = -1
#6 has alternative solution: move vertical match from "+" to "1" to make "7"
That was my solution too.😊
Yup
@@soulrevolutionradio8011 The rules say you're not allowed to do that.
@@soulrevolutionradio8011it will not be equation. Also it is said in the start that it is not allowed
7-2=5
@4:36 can also be solved to 7 - 2 = 5 by moving vertical stick of plus sign toadd to first stick making the 1 a 7 .....double solution!
no
#13. I was going to suggest grab the match on top of the 7, break it in two and put the small pieces over and under the - (minus) symbol to turn it into ÷ (division). So 4/4=1 😹
Puzzle 2. Move the upright stick from the plus sign to make a 9 out of the first number. 9-6=3
That's not the representation of a 9. Moving 1 stick to or from a 4 won't make it another number. To be become another numbers needs the following moves: 1(remove 2), 2 (reallocation of two and add one), 3 (one reallocation and add one), 5( one reallocation and add one), 6 (one reallocation and add one), 7 (one reallocation and remove 1), 8(three new ones), 9 (two new ones). A 4 cannot become another number with only one move.
On Puzzle 6 I had a different way. I moved the vertical matchstick from the addition sign and moved it horizontally at the top of number 1. Which is 7 - 2 = 5 instead of 1 + 2 = 3.
I also found an alternative answer on Puzzle 11. Instead of 4 + 5 = 7, my alternative answer is -4 + 5 = 1. I’ve done it by moving the horizontal matchstick from the top of 7 and moved it next to the 4 in the beginning of the equation.
By the way, this is a good logic test to get my brain going. Looking forward to more logic videos like this.
Same on puzzle 1
Same
Right
Very nice logic test to get my brain going at the start of the day, thank you.
Rearranging some of the answers, though, breaks the rule of moving only 1 stick. 🙂
Alternative solutions
#6: use the vertical stick of the plus to turn the 1 into a 7; 7 - 2 = 5
#14: The same as in #5 and #9, use the horizontal stick of the 7 to turn the 1 to a 7; 6 + 1 = 7
#2 9 - 6 = 3
#12 - 0 + 0 = 0
#13 - take the horizontal bar from the 7. Break it in half and put the halves above and below the - sign to make it a division sign
#14 - 6-7 = -1
The 0+0=6 can also be changed to 0+0=0
That was my initial guess
That was my answer too.
question no.2 4+6 = 3 answer move the upright stick from the + and place ontop of the 4 making it a 9 = 9 - 6 = 3
Very good .
I found it easier to think about the possible options mathematically first, then it was easy to spot how you could get numbers you need.
Same
#14 the vertical stick on the "+" can be moved to the other side of the "=" to make "-1", giving: 6-7=-1
And the horizontal one of the 7 can be put at the 1 to get 6+1=7
Note, these are guesses while the video is paused between each problem.
Problem 1: Swap the top left of the 9 to make it 3, put it on the bottom left of the 5 to make it 6. 3+6=9
Problem 2: Swap Bottom left of 6 to make it 5, put it on top left of 3 to make it 9. 4+5=9
Problem 3: Swap the vertical line of the plus sign, making it a minus sign, and put it on the 1 to make it 7. 7-5=2
Problem 4: Rotate the middle line of the 4 clockwise to turn it into 11. 11-5=6
Problem 5: Swap the top line of the 7 to make it a 1 and move it on the bottom left of the 5 to make it a 6. 6+1=7
Problem 6: Same as problem 3. 7-2=5
Problem 7: Swap the top right line of 8 to make it a 6 and put it on the bottom left of the 9 to make it an 8. 8-6=2
Problem 8: Two possible solutions for similar answers. Either rotate the middle line of the 6 clockwise to make it a 0 (8+0=8) or Swap the middle line of 8 to make it a 0 and put it in the top right of the 6 to make it an 8. 0+8=8
Problem 9: Swap the top line of 7 to make it a 1 and put it on top of the 1 to make it a 7. 1+6=7
Problem 10: Same as problem 7. 2+6=8
Problem 11: Swap the top left line of the 5 and put it on the top right to make it a 3. 4+3=7
Problem 12: Spotting three solutions for this one, with two of them being almost identical. For the identical ones, take a 0 and rotate the top right line counter-clockwise to make it a 6. Depending on the 0 you pick, it's either 6+0=6 or 0+6=6. Or, you can rotate the middle line of the 6 clockwise to make it a 0 for 0+0=0
Problem 13: Same as problem 4. 11-4=7
Problem 14: Same is problem 9. 6+1=7
Problem 15: Swap the top right stick on the 9 and put it on the bottom left to make it a 6. 7-1=6
problem 14 alternative solution: 6-7=-1
Or 3+5=8😊
@@user-nx2sw7sx7pI was thinking the same thing as my first guess
№14 6+1=7
(1) 3+6=9
Problem #2 take the vertical plus sign and make it a - then put it on top of the 4 making it a 9 then you have 9-6=3
0+0=6...instead of changing a zero to a 6 (0+6=6) I changed the 6 to a zero...0+0=0.
They rest came up with your solution. 😊
#8
0+8=8
Center stick of 8 move to upright of 6.
#14
6-7=-1
In problem no. 6
There is 1+2=5
There we can remove one stick from the '+' sign and join horizontally with the no. 1. So, we get here
7 - 2 = 5
i found this one too.
These are kind of fun and interesting. Thanks for this!
- 4 + 5 = 1 alternative solution for 3+4=7 ….. #11
Wow it's amazing....
It's good for learning with kids.
Move the "cross bar" of the first 4, by rotating it DOWN a quarter turn (90º) to turn the 4 into an 11 : 11 - 4 = 7.
Ha good one on the thumbnail. Took me a minute to figure it out what to do with 4 - 4 ! Very devious!! I approve...
Everybody is here for the alternate answers. The only one that tricked me was the 4 turning into 11. I was expecting negative answers by moving half the plus sign. Haha, no inequalities. They could mostly be solved that way. 😂 I paused a lot though. Some took several minutes. Some I solved multiple ways instantly. I am calling myself below average on this. I only gave up on the 4 to 11 one.
Me too
They actually move 2 left sticks a bit closer, to make number 11, and I believe this is against the rule...
amazing, greetings from Bolivia
3+5=8
Puzzle 12 change the top right second 0 to make a 6 0+6=6
11 - 4 = 7 ....
move 1 horizontal stick on first 4 and make number 11...
1st one 3+6=9
-4+5=1
Puzzle 11 could have been changed into -4 + 5 = 1 and would be correct. I'm sure there is more than one way to solve most of them without using the illegal symbols stated at the start of the video.
Yup. :) I liked this solution.
1+2=3
6+1=7
Question 14 answer 2, move the top line on the seven to the top of the one and then it’s 6+1=7
8:59 another answer could be 0+0=0.
#12 I moved the middle stick on the answer 6 to make the equation 0+0=0 😂 What I saw first, and still was a correct answer! LOL
11 - 4 = 7
№11 -4+5=1
11-4 = 7
The 1st one that I've solved 🎉🎉🎉
Simple, I’d take the matchstick between the fours and place it diagonally “/“ over the two “equals” matchsticks.
9:39 Is breaking a stick allowed? If so, then I solved puzzle 13 with 4/4=1, by breaking the top stick of 7 and making a traditional dot-above-and-below-a-minus-sign divided by symbol, like a % straightened out. I noticed that when solving the thumbnail before I clicked.
7-5=2
Alt solution for #12
From 0+0=6 make 0+0=0
1+6=7
Alternative solution for the 8th: take the central stick of the first 8 and put it in the 6, it will be 0+8=8
4:32 7-2=5
A harder mathematical problem:
Find all of the solutions to the match stick problem (prove there are no other solutions outside of this set).
That should be more difficult - I don’t think that math exists yet. I could be wrong.
The reason I don’t think the math exists, is because the match stick problem uses a set of specific symbols, that are meaningless in math - and therefore, we would need to make new math to describe their behavior.
It is possible that the math exists if we apply some method of abstraction (if the symbols were similar enough to graphTheory or latticeTheory for example)
No.1 could be 3+6=9
12 can be also soved as the 6 is converted to 0 the same way the 0 is converted to 6
7-2=5
2nd one could be 9-6=3 if rotations are allowed
Puzzle 6: move the horizontal match from the + to the 1 to make 7-2=5
Puzzle 8: move the middle match from the first 8 to the 6 to make 0+8=8
Puzzle 12: rotate the middle match in the second 6 onto the empty spot on the same number creating 0+0=0
Puzzle 14: move the top match on the 7 to the 1 creating 6+1=7
1:44 or you could grab a match from the top cross in the addition symbol to make the 4 a 9 so 9 - 6 = 3
1+2=5 could also have been 7-2=5
8:54 0+0=0 also possible
9:50 6-7 = -1 also possible
For 6 I have a different solution. Move the stick from the plus sign (making it a minus) and add it to the 1 , giving you 7-2=5
I got 7/15 and On number 12 there was 3 ways to do it!
On number 14 you could have moved the stick on top of the seven to the top of the 1
Second question. 4+6=3. Ans. 4+5=9
The only easiest solution here is take the equation and make it an *inequation*
Like 4-4=7, move the horizontal line in the 7, rotate it 45° counter clockwise and place it in the equal sign.
Now you get 4-4≠1
Haven’t seen the video. But you solve the thumbnail by making it 11-4=7.
#1 ( 3+6 = 9 ) y/o (3 + 5 = 8)
8-6=2
Oh tooo hard that I can't do all of the answers
But I love studying math you are the best channel
Damm getting the 4 into a 11 took me ages ... just was not thinking 2 digits I guess 🥴
9+5=9
Move the match from the 9 making it a 3 and add the match to 9 making it an 8 so you have 3+5=8😊
#6 :
7-2=5
9-6=3
7-2=5
i did the no. 2 differently.
from 4+6=3 ....to.... 9-6=3. (u move the vertical stick from + and put it on top of 4, then u'll get 9)
#14
6-7 = -1
They were much easier than i thought. Fun though.
#6 take a stick from + sign making it -, move it to 1 to make it a 7
7-2=5
#6 can also be 7-2=5
#12 can also be 0+6=6 or 0+0=0
#14 can also be 6+1=7
Alternative to #2. Take the up match from the plus sign and put it on top of the four. 9-6=3. Puzzle 12 easy alternative answer is move the horizontal stick on six to make it a zero as well. Didn't look at any previous answers prior to submitting the above.
Puzzle 12: 0+0=0 (communicative if second 6)
Puzzle 14: 7-8=-1
2+6=8
Made seven of them
Puzzle 14 remove the top of 7 and put it on 1 to make 6+1=7
puzzle #6... move 1 stick from + sign to form 7... 7 - 2 = 5
11-4=7.
Took me about 15 seconds.
11 - 4 = 7 ❤
#14
6+1=7 is also the answer
#6 could also be 7-2=5
Moving one match to convert the 'equal' sign to a 'not equal' sign makes everything piss easy and still mathematically correct.
8:54 "0+0=6 goes to 0+0=0" True
#6 1+2=5 remove a stick from the + add it to the to of the 1 to make 7-2=5
0+0=0 for #12
Puzzle number 14. Take vertical stick from + and put it in front of 1. It makes 6-7=-1
0+8=8
04:30
Answear: 1+2=3
My answear: 7-2=5
#1 and #6 have two solutions.
Near the end, you get a feel for the patterns and it gets easier.
Also #2, it can be 9-6=3
12 too
#6 7-2=5
13 is EZ. Take the minus sign, rotate it diagonally and put it over the equal sign. 44 does not equal 7.
#1: 3+6=9
#12: 0+0=0
