Matchstick Puzzle

Say you have matchsticks in the form of the Roman Numerals X - X = X. You have to move one matchstick to make this sequence not wrong. X - X = X  (10 - 10 = 10.)

Hint: Not wrong.

Re: Matchstick Puzzle

How do you that that is not wrong?

By the way, X is 10, not 5.

Re: Matchstick Puzzle

Oops, that was a big blunder. Well, "not wrong" is the definition of correct, and on many math problems they say "which of the following statements makes the equation correct." And I don't know of any way you can make it correct.
