It IS true.
Any LUEsers here?
-
- = unary operator and takes precedence over everything
No.
-
I'm not a LUEser, but
-4^2 = -(4^2) = -(16) = -16
Quite simple, actually.

...But -4^2 does not equal -(4^2), as far as I know.
Oh and I am proud of not being a LUEser, kthx.

ybbun is correct; (-4)² = 16, -4² = -16. Mathematics is not computer science, unary operators are irrelevant.
-
2 or 3 topics with the same title as this got over 200 replies in LUE.
I can't go there any more, but I don't really care.

Ow my ears.
Anyways...
-(4^2) = -16
-4^2 =! -(4^2)
(-4^2) = -4^2
-4^2 = 16

Still wrong, because mathematics is still not computer science; "-" functions the same way whether it is being used as a negative or for subtraction, the only difference being that the former method has an implied 0 in front (ie, -5 = 0-5).
There is a reason it works this way. Consider this:
x = -4²
y = 2-4²
I think most people will agree that y = 2 - (4²) = -14, because powers take precedence over additive operations. It would be disjointed for the first example to work differently because of the lack of a number (or if you don't think so, work with polynomials more and you'll change your mind).
Actually, that's a good example as well - nobody construes -x² as being (-x)², right? Well, why should it work any differently with a number as with a symbol? No other operations change how they work based on whether they operate on numbers or symbols.

I thought I was smart at maths cause i know what 2111squared is and I'm in year 5 but this is weird.
-
They are talking about college math or something
I'm only in geometry...
so...
*steps away*
BTW, Theorems are no fun :D

Yeah... but this topic was dead, you didn't have to revive it just so we realise you're only 10 years old...

It is true...
