288 is the final answer everyone agreed on.

They aren't the same, though.
The first one is:
(-11)[sup]2[/sup]
= (-11)(-11)
= 121
The second is:
-(11)[sup]2[/sup]
= -[(11)(11)] or written more simply: (-1)(11)(11)
= -121
It's a common trick question on 9th grade algebra exams.
You didn't post what he posted though. I completely agree with you on what you said. Maybe if you actually read this thread you would have seen my big post about this.
What dude said is:
-11^2
and
-(11)^2
are different. I think that you can clearly see these two problems are the same. Did you think you were gonna try to son me saying these are problems on 9th grade exams
And thank you Klipschorn
HOW DO YA'LL NOT BELIEVE THIS MAN, SON EVEN HAS NEWTON AS HIS AVY

Typing -11^2 into a calculator/wolfram gives you -121 because computers parse the expression as -1 * 11^2, rather than as (-11)^2. your calculator/wolfram isn't wrong at all. Due to the ambiguity of the negative sign for computers, you always need the parens around the base of your exponent for the correct computation
Thank you, finally someone with some common sense.
