Answer:
7
Explanation:
order of operations is PEMDAS
Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.
-5 + 3 (7.2 - 3.2)
First you need to do the math for what is inside the parenthesis.
7.2 - 3.2 = 4
there are no exponents so next step is to multiply.
So you need to multiply
3 x 4 = 12
then there is no division so next step is to add.
-5 + 12 = 7
that is the pest step since there is no subtraction
