Arlinda N.

Answer:

Solution: 11 When uing PEMDAS, the problem should be solved in the given order. The first letter, P, stands for parenthesis. That means that the numbers in parenthesis should be solved first (10+3). The next letter, E, stands for Exponents (3^2). After solving the two smaller equations, the problem would be shown as 5+9-13+5x2. The following letters, MDAS, mean that the remaining problem should be solved in order of Multiplication, Division, Addition, then, Subtraction. After following these steps, you are given the answer of 11.
