- 3^2 = - 3*3 = -9

(-3)^2 = -3 * -3 = +9

- 3^3 = - 3*3*3 = -27

(-3)^3 = -3 * -3 * - 3 = -27

(-5)^2 = 25

so

- (-5)^2 = -25

Do everything inside parentheses before doing anything else.

in the first, -3^2 is ambigous. IT could mean -9 (the negative of three squared) or 9 (negative three squared).

On the second, in either case it is -9

on the last, -(-5^2)=- 25
