Question

How would you solve this problem using the order of operations?
8+(5)(4)-(6+10÷2)+55

Answer 1

72

Explanation:

Use PEMDAS

Parentheses

Exponent

Multiplication and Division (if it contains both, just go from left to right)

Addition and Subtraction (if it contains both, just go from left to right)

8 + (5)(4) − (6 + 10/2) + 55

8 + 20 − (6 + 10/2) + 55

28 − (6 + 10/2) + 55

28 − (6 + 5) + 55

28 − 11 + 55

17 + 55

72

To solve it step by step with PEMDAS:

Solve within the parentheses

6 + 10/2

10/2 = 5

6 + 5 = 11

Multiply/Divide

(5)(4) = 20

Add/Subtract

8 + 20 - 11 + 55 = 72
