Was there ever a conclusion here as to what is correct?
I would of done it like this:
(-2)^2 = 4

>>>This is a very interresting discussion. I would have gone along with you on the unary operator being a higher precedence than exponentiation. However, after reading this thread adn the supporting links to the various arguments I am beginning to agree with the idea that unary sign is at the precedence evel of multiplication and division.
