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
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
6th one could be 7 - 2 = 5
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
#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
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
#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. 🙂
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
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
#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 правильных решений. Спасибо🎉😊
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.
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.
2nd one could be 9-6=3 if rotations are allowed
These are kind of fun and interesting. Thanks for this!
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 .
#14 : from 6+ 7 = 1 ---> 6 +1=7
also: 6 - 7 = -1
amazing, greetings from Bolivia
The 0+0=6 can also be changed to 0+0=0
That was my initial guess
That was my answer too.
Simple, I’d take the matchstick between the fours and place it diagonally “/“ over the two “equals” matchsticks.
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...
Wow it's amazing....
It's good for learning with kids.
#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
Ha good one on the thumbnail. Took me a minute to figure it out what to do with 4 - 4 ! Very devious!! I approve...
Damm getting the 4 into a 11 took me ages ... just was not thinking 2 digits I guess 🥴
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
#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
At #14: You could move a stick from the 7 to the left over to the 1 on the right and get the equation 6 + 1 = 7.
yea
@ 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
Or the first on: 3 + 6 = 9
I also picked #14 the same 6+1=7
#14 or 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.
And by moving 2 matchsticks, we have the same equation as the one obtained by moving 1 matchstick, but in different form.
They were much easier than i thought. Fun though.
12 can be also soved as the 6 is converted to 0 the same way the 0 is converted to 6
Got one right. About to give up around #6
Very easy !!
Move a single match stick to create a "does not equal" sign in many cases.
Rules in the beginning state that this is not allowed. It’s too easy.
11 - 4 = 7 ....
move 1 horizontal stick on first 4 and make number 11...
8:59 another answer could be 0+0=0.
Very,very good.
This Video Make Me Smart
Thanks a lot to you.
For number 9 you can make the one taller, give it that diagonal thing or a bottom
lolo didnt get the 1st one the 2nd one can be also be done with 9-6=3, and #6 can be done also with 7-2=5 but then am i allowed to change signs.. i got caught out with the 11-5 lol that was sly of you good fun thanks.
Some of the puzzles have more than one solution.
#9 : 7-6 = 1
removing the vertical bar from the + but not putting it elsewhere is valid ?
#14 : 6 - 7 = -1 ?
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 - 4 = 7 simples, movendo do 1° 4 um palito para baixo😅
Made seven of them
11/15 😅
Great!!
I like the tune
different solution - second one - make it 9 - 5 =3 moving vertical plus to the top of the 4
Move one stick in the 1st 4 to make into a 11
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
So far I've noticed that some of these equations have double solutions. Without breaking the rules, are there any triples?
Бессмысленные головоломки! Если ты не знаешь чего хочешь, разве можно что то сделать? 😊
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

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?"
Thank you for naming that song, I kind of fell for it, very nice music!
Got 9 out of 15. Should have gotten 11.

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. 😊
№14 6+1=7
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
8:54 "0+0=6 goes to 0+0=0" True
Question 14 answer 2, move the top line on the seven to the top of the one and then it’s 6+1=7
Из4 опускаем среднюю спичку,получаем 11. 11-4=7
there is a second answer for #2 (take the vertical stick from the plus and it becomes a minus), then add it to the top of the 4 to make 9. 9-6=3
11...
1+2=5 could also have been 7-2=5
11-4 = 7
The 1st one that I've solved 🎉🎉🎉
о, я на половину ответила )))
I needed now time to get them right
10/15 W
13 is EZ. Take the minus sign, rotate it diagonally and put it over the equal sign. 44 does not equal 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.
1st one 3+6=9
Puzzle 4 alternative solution: Move the leftmost stick of the 4 infront of the 6:
-1-5=-6
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.
Alt solution for #12
From 0+0=6 make 0+0=0
On number two take the up and down stick from the plus sign and put it on top of the four.
Best comet ever
Puzzle 2, move one from the + sign to the 4 to make it 9-6=3.
7-2=5
44不等於7。移動中間的一放在等號放成斜槓/。
At first equation I didn't really understand the concept, then by the second one I started thinking three-dimensionally, by the third one I got everyone alright till the end of the video! I had a professor where I went to college at that used to draw two-dimensional diagrams on a chalk board, (old school), triangle, circle, square. Then asks, how many sides, to each? Amazing!
3+6=9 - проще некуда ...
#6 could also be 7-2=5
# 11 top 7 moves to -4+5 = 1
There’s an alternate answer on puzzle 9
You can turn the plus sign into a minus sign and then just put that stick to the side
I mean, simply logical didn’t say that we couldn’t put a stick to the side
In any of them you can move 1 stick to make a does not equal sign, and its a true mathematical statement
14/15
Puzzle 12 change the top right second 0 to make a 6 0+6=6
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)
