Answer:
42
Step-by-step explanation:
This is called PEMDAS: PEMDAS is the abbreviation of the term, "Please Excuse My Dear Aunt Sally" or, "Parenthese, Exponents, Multiplication, Division, Addition, and Subtraction."
9 (3 + 3) - (16 - 4)
3 + 3 = 6
If anything is by a parenthesis that means its multiplication.
9 x 6 - (16 - 4)
16 - 4 = 12
9 x 6 - 12
9 x 6 = 54
54 - 12 = 42.
