Question

Evaluate 15 - 4 + (7 - 5)^2 = __________.

Answer 1

use BEDMAS.

Answer 2

=15 - 4 + (2)^2
= 15 - 4 + 4
= 15

Answer 3

ok so again you use PEMDAS for this so we focus on the parentheses first.
So we know 7-5=2
so now we need to do 2^2 or 2*2 which is 4
so now you have: 15-4+4

Answer 4

so we be back in 15 after 15-4 plus 4

Answer 5

yep we have 15-4+4.
and -4+4= 0 so we know that the answer is 15
