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.
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.
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.
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
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
#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. 🙂
@ 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
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.
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.
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.
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
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.
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
#14: 6+7=1 Your answer ( 8 - 7 = 1 ). It can made in this way, moved the top stick from 7 to the 1 , ( 6 + 1 = 7 ) which was still kept in the way of addition.
#14 Alt. A: Turn the plus sign into a minus sign and make the answer = -1. (I'm sorry but, I don't recall anything being said about use of negative numbers.)
There is another solution to the 14th problem. You can take the top match off the 7, and that will turn it into a 1. You put that top match on top of the 1, and that will turn it into a 7. That would turn that problem into 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.
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.

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.

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.

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.
#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

9:09 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.
Класс! Я не догадалась. Вот, что значит пространственное воображение!
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.

Rearranging some of the answers, though, breaks the rule of moving only 1 stick. 🙂
The 0+0=6 can also be changed to 0+0=0
That was my initial guess
That was my answer too.
#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
@ 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
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

Yup. :) I liked this solution.
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
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!
#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

They actually move 2 left sticks a bit closer, to make number 11, and I believe this is against the rule...

#12 alternate solution: 0 + 0 = 6
We also can move the central stick from 6 to make a 0. Then 0 + 0 = 0 😊

Muy interesante gracias por la información y la agilidad mental.
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
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
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
amazing, greetings from Bolivia
Puzzle number two, move the match from the plus sign to make it a minus sign, and put it on top of the four to make it a nine . 9 - 6 = 3
Interesting video
Glad you think so!
12 can be also soved as the 6 is converted to 0 the same way the 0 is converted to 6
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
5:03 dont need to move anything, just turn the screen upside down to solve it
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
8:54 0+0=0 also possible
9:50 6-7 = -1 also possible

Q 14- 6 made to 8, 8-7=1. The other way is move top stick from to other side where 1 is there. 1 becomes 7. So, 6+1=7
Got one right. About to give up around #6
8:59 another answer could be 0+0=0.
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)
Simple, I’d take the matchstick between the fours and place it diagonally “/“ over the two “equals” matchsticks.
I like your background beats 👋❤
Question 6 alternative answer. Change the plus into minus by taking the upper matchstick. Place it on the first digit to make 7: 7-2 = 5
2:18 Move the top of the 2 to make the 2 into the 6.
If you take the top line from seven and then you move it to the number one and make a seven 6+1=7. 10:03
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 number 14. Take vertical stick from + and put it in front of 1. It makes 6-7=-1
4 - 4 = 7: put the minus on the equal sign. 44 ≠ 7
The rules don't allow that.
different solution - second one - make it 9 - 5 =3 moving vertical plus to the top of the 4
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
Puzzle 2, move one from the + sign to the 4 to make it 9-6=3.
They were much easier than i thought. Fun though.
#8
0+8=8
Center stick of 8 move to upright of 6.
#14
6-7=-1
13 is EZ. Take the minus sign, rotate it diagonally and put it over the equal sign. 44 does not equal 7.
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😊
Moving one match to convert the 'equal' sign to a 'not equal' sign makes everything piss easy and still mathematically correct.
#14: 6+7=1 Your answer ( 8 - 7 = 1 ). It can made in this way, moved the top stick from 7 to the 1 , ( 6 + 1 = 7 ) which was still kept in the way of addition.
This way is more easier and logical.
#14 6+7=1, remove the vertical stick from the plus and add it to the answer as a negative sign --> 6-7=-1
For puzzle #6, move the vertical match from the plus sign to the first number to make it a 7. So, 7 - 2 = 5
Alt solution for #12
From 0+0=6 make 0+0=0
I like the tune
#12 Alternative answer: Turn the six on the right into a zero. i.e.--0+0=0
#14 Alt. A: Turn the plus sign into a minus sign and make the answer = -1.
(I'm sorry but, I don't recall anything being said about use of negative numbers.)
Ha good one on the thumbnail. Took me a minute to figure it out what to do with 4 - 4 ! Very devious!! I approve...
Puzzle 12 change the top right second 0 to make a 6 0+6=6

#1... top left stick of left most 9 to bottom left of right most 9 = 3+5=8.
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
- 4 + 5 = 1 alternative solution for 3+4=7 ….. #11
puzzle #6... move 1 stick from + sign to form 7... 7 - 2 = 5
Puzzle 4 alternative solution: Move the leftmost stick of the 4 infront of the 6:
-1-5=-6
So far I've noticed that some of these equations have double solutions. Without breaking the rules, are there any triples?
#6 take a stick from + sign making it -, move it to 1 to make it a 7
7-2=5
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
There is another solution to the 14th problem. You can take the top match off the 7, and that will turn it into a 1. You put that top match on top of the 1, and that will turn it into a 7. That would turn that problem into 6+1= 7.
Very,very good.
