ooh goddd I voted wrong but right after realized it was a trick! :'( I'm so dumb.

Aww I didn't realize ^ meant to the power of. =/

Is this supposed to be -(4^2) or (-4)^2? --- Step outside, take a breath of fresh air, then look down to see if you have a new text message.

What's written in the question is enough to determine which of that it is :P

Definitely read the ^ as a /, hence voting for None of the Above... *headdesk* Books & More http://www.neopets.com/browseshop.phtml?owner=starr_2525

What's written in the question is enough to determine which of that it is --- 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 ;) --- Step outside, take a breath of fresh air, then look down to see if you have a new text message.

The way I was taught, it should be read as -(4^2).

I think it really is -(4^2), so if that is true, about 76% of neomallers don't know the answer. --- Step outside, take a breath of fresh air, then look down to see if you have a new text message.

Yep. order of operations tell you to evaluate the exponents first, before the subtraction

Say what?

It really just depends on what way you were taught and who is writing the question. It should have parenthesis to specify.

No if it had parenthesis, it would be a totally different question.

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

naa saw it on ur lookup earlier

You can get the actual answer by googling this equation

I learned from the start of school that without brackets it's negative something.

What I learned it as was Gemdas (Groups (brackets, ()'s, division bars with more that one thing on top or bottom), Exponents, multiply/divide in left to right, add/subtract left to right.) --- Step outside, take a breath of fresh air, then look down to see if you have a new text message.

It's odd then that I learned Gemdas, though I'm in the US. --- "Opportunity is missed by most because it is dressed in overalls and looks like work." -Thomas Edison

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.
