Matchstick PuzzleSay 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 PuzzleHow do you that that is not wrong?

Re: Matchstick PuzzleOops, 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.  n872yt3r Math Is Fun Rocks! By the power of the exponent, I square and cube you!
