# Squared numbers

Why do negative numbers which are squared by a even number always return as a negative while using a calculator? e.g. (-1)^2 = 1, except calculators say -1, even though -1*-1 = 1 :S:S

Well, if you type it in like this: -1^2 then the calculator interprets it as -(1^2)=-1. try inputting (-1)^2.

Oh okay, thanks.
