You can move one digit only to make this equation balance.

62 - 63 = 1

You can't move the symbols, only the numbers, so moving one of the lines of the equals onto the minus isn't the answer.

The one digit you move, you can move any way you want, the rest stays where it is.

Replies welcome, because my son won't tell me the answer.

He solved it, so he says I should too!

lol that's easy!
edit: well in french you don't have to add a sign for what i'm doing, but it seems english speakers have a sign for it, in which case it wouldn't work for english speakers .....So not sure my answer is the one you're looking for , and i don't have any other!

took me a bit under a minute, i think that's pretty OK for someone who dropped out of high school and never paid attention in math class

I had to look it up tho.

I like this one...

A rooster lays an egg at the very top of a slanted roof. Which side is the egg going to roll off on?

Roosters don't lay eggs.

You swap the 62 with the 63 and it makes the statment true.
Am I right?

I don't understand the directions of the puzzle so I can't solve it. Anyone else with this same problem?

I feel cheated! You never said that I could change the size of the digit!

This puzzle can only be solved by people who don't care about correct mathematical typography. And such people are the scum of the earth! The scum of the earth I tell you!

Maybe I just have to take a liberal interpretation of "move". :wink:
