ooh goddd I voted wrong but right after realized it was a trick! Cray 2 I'm so dumb.

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

Is this supposed to be -(4^2) or (-4)^2?

What's written in the question is enough to determine which of that it is Blum 3

Definitely read the ^ as a /, hence voting for None of the Above... *headdesk*

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 Wink

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


Hehe, apparently three quarters of neomallers didn't learn that rule in algebra. :O

I think it really is -(4^2), so if that is true, about 76% of neomallers don't know the answer.

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 Smile

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. Recently, in higher grades, teacher's get lazy and they don't put the brackets but you know that it becomes positive.

It does not become positive due to the rules of BEDMAS/Order of Operations

What I meant was
-2^2 = -4
(-2)^2 = 4
-(2)^2 = -4

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.)

I learned it as PEMDAS

Parenthesis
Exponents
Multiplication & Division go in order of whichever comes first
Addition & Subtract (same as ^^)

The U.S learns it as PEDMAS. Everywhere else (Canada, Europe, etc) learn it as BEDMAS. sorta like the metrics system

It's odd then that I learned Gemdas, though I'm in the US.

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.
