Answer:
72
Step-by-step 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
