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.

12th could be 0 + 0 = 0

Puzzle 1. Move the same matchstick to form the second number to a 6. 3+6 = 9

6th one could be 7 - 2 = 5

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.

Puzzle 2. Move the upright stick from the plus sign to make a 9 out of the first number. 9-6=3

#6 has alternative solution: move vertical match from "+" to "1" to make "7"

@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!

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.

#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 😹

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. 🙂

#14 the vertical stick on the "+" can be moved to the other side of the "=" to make "-1", giving: 6-7=-1

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

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.

#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

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

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

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

#14 : from 6+ 7 = 1 ---> 6 +1=7

Got one right. About to give up around #6

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.

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.

Wow it's amazing.... It's good for learning with kids.

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.

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

Damm getting the 4 into a 11 took me ages ... just was not thinking 2 digits I guess 🥴

2nd one could be 9-6=3 if rotations are allowed

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. 😊

They were much easier than i thought. Fun though.

These are kind of fun and interesting. Thanks for this!

Very,very good.

№14 6+1=7

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

amazing, greetings from Bolivia

I like the tune

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)

4:32 7-2=5

Ha good one on the thumbnail. Took me a minute to figure it out what to do with 4 - 4 ! Very devious!! I approve...

7-2=5

8:54 "0+0=6 goes to 0+0=0" True

11 - 4 = 7 .... move 1 horizontal stick on first 4 and make number 11...

#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

Alt solution for #12 From 0+0=6 make 0+0=0

Got 9 out of 15. Should have gotten 11.

Simple, I’d take the matchstick between the fours and place it diagonally “/“ over the two “equals” matchsticks.

Made seven of them

#1 and #6 have two solutions. Near the end, you get a feel for the patterns and it gets easier.

3+5=8

Oh tooo hard that I can't do all of the answers But I love studying math you are the best channel

11-4 = 7 The 1st one that I've solved 🎉🎉🎉

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.

11-5=6

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

Moving one match to convert the 'equal' sign to a 'not equal' sign makes everything piss easy and still mathematically correct.

Great!!

8:59 another answer could be 0+0=0.

Very easy !!

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

Haven’t seen the video. But you solve the thumbnail by making it 11-4=7.

#8 0+8=8 Center stick of 8 move to upright of 6. #14 6-7=-1

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

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.

12 can be also soved as the 6 is converted to 0 the same way the 0 is converted to 6

Question 14 answer 2, move the top line on the seven to the top of the one and then it’s 6+1=7

In the one from the thumbnail (4+4=7), I personally prefer the solution of taking the stick from the top of the 7, break the mf'er in half and use each half to make a dot above and below the minus sign.

Бессмысленные головоломки! Если ты не знаешь чего хочешь, разве можно что то сделать? 😊

8-6=2

4-4≠1 "sometimes my genius is almost frightening"

7-5=2

13 is EZ. Take the minus sign, rotate it diagonally and put it over the equal sign. 44 does not equal 7.

- 4 + 5 = 1 alternative solution for 3+4=7 ….. #11

Puzzle number 14. Take vertical stick from + and put it in front of 1. It makes 6-7=-1

Tujuh atas geser ke lima bawah depan

1+2=3

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

Puzzle 12 change the top right second 0 to make a 6 0+6=6

1st one 3+6=9

1+2=5 could also have been 7-2=5

There is also a difference between digital and analog numbers, you wouldn't write these numbers on a piece of paper and ask people to fix the equation by moving a matchstick right? Still a really cool experiment!

This Video Make Me Smart

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)

Puzzle 12. Move middle stick making a zero. 0+0=0

Oi! Matchstick Man! 😛

In the second puzzle, you also can take a match from the + and place it on the 4, so it becomes a 9, and then, you have 9-6= 3

11...

11-4=7. Took me about 15 seconds.

Puzzle 2, move one from the + sign to the 4 to make it 9-6=3.

Thanks a lot to you.

I was more fixated on the music than the equations. That song "Read All Over" by Nathan Moore reminds me of Nelly Furtado's "Why Do All Good Things Come To An End?"

Puzzle 8 move the centre stick from the first eight to make the 6 an 8 so it’s 0+8=8 (you did 8+0=8)

10/15 W

2+6=8

@ 11:05 #14 can also be solved as 6 + 1 =7 moved horizontal stick of middle digit changing it to a 1, placing free stic at top left of 1 at the end, making it a 7

No.1 could be 3+6=9

For puzzle #6, move the vertical match from the plus sign to the first number to make it a 7. So, 7 - 2 = 5

i stink at math this was cool

14/15

Well. That's not exactly challenging. Got all of those without overly thinking about it. Several of them also have alternative solutions
