-380+15

Always remember P.E.M.D.A.S (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

In that order, solve the problem. Multiplication and Division go left from right and so do Addition and Subtraction.

4 - 9 + ( 7 x 11 ) x 5 + 7 + 8

Parentheses

4 - 9 + (77) x 5 + 7 + 7

Multiplication

4 - 9 + 385 + 7 + 7

Addition and Subtraction

-5 + 385 + 7 + 7

380 + 7 + 7

387 + 7

394
