Context is everything. I

Context is everything. In C++, -4^2 = -2, which would be "None of the Above". ^ is the "exclusive or" operator and has lower precedence than unary minus.

I learned from the start

I learned from the start of school that without brackets it's negative something. Recently, in higher grades, teacher's get lazy and they don't put the brackets but you know that it becomes positive.

Heh, the more I think about this, the more it blows my mind.
-(a big log equation)^2 would probably not be a problem for anyone,
but suddenly -(x)^2, or -x^2, is different. I'm included in that happy

Interesting, I'd still like to see the history on it all!

Well, Last year I had a teacher who said that it would be (-4)^2 and this year one that says it would be -(4^2) (Which I think makes more sense). It's not my fault that I'm stupid winking
