This teaser requires 30 toothpicks to do.
Place the toothpicks in a way so that they read "82 - 41 = 43" in digital numbers. (To avoid ambiguity, the 4 must be made with perpendicularly placed lines.) You may not modify the equal sign in any way.
Now, the challenge: move only one toothpick to make the equation true.

Hint
Moving two is too easy, just change the 2 to 3 and the 3 to 2. Think outside the box.Answer
Move the toothpick in the middle of the 8, and place it crossing and perpendicular to the minus, turning it into a plus sign. The equation should now read "02 + 41 = 43" which is correct!Hide Hint Show Hint Hide Answer Show Answer

This was a great teaser. Keep making them. This one was also very tough for me. Course I am almost a teenager but still, great job. I can't wait to see more from you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I'm only a teenager myself. When I gave this puzzle to real people in real life, about 99% couldn't figure it out.
ima get on this tv mamma ima put sh*t down
There are a lot of alternative answers to this question. One example:
82-41 does not sign 3
82-41 does not sign 3
does not equal sign, sorry
Er.... I explicitly said that you can't modify the equal sign... meaning you can't turn it into a not-equal sign. So I'm thinking it should be the only answer.
Great teaser!
easy and fun...keep them coming...
... I was gonna say not equal but then when I looked closer it said to not modify equals sign
Nice teaser. Just shows for me though, I am too lazy to go get thirty toothpicks... but I liked it. Very clever!
That was fun! I pondered a while, looked at hint, but I didn't get it!
