Use order of operations to simplify.

4 - 10 + 12 / 3 + (7^2 - 7)

Order of Operations = Please Excuse My Dear Aunt Sally, PEMDAS. P= Parentheses E=Exponents M= Multiplication D= Division A= Addition and S= Subtraction in that order.

The answer
4-10+12/3+(7^2-7)
4-10+12/3+(49-7)
4-10+12/3+56
4-10+4+56
4-14+56
4-70
-66

-66 should be your answer if i’m not mistaken
