Question

If a=-3 what’s a squared

Answer 1

a^2=9

Explanation:

there is a rule that states that if you multiply - with - it becomes + so a number squared just means that the number multiplies with itself so -3*-3=+9 or 9 (any number with + can be written as the number without the +sign, for ex. +1 is the same as 1)

Answer 2

-3 squared is 9 because -3•-3=9.
