Step-by-step explanation:
Use the order of operations acronym PEMDAS to evaluate expressions with mixed operations.
P- parenthesis, E- exponents, M- multiplication, D- division, A- addition and
S- subtraction
1
4 ÷ 2 + 5 - 3 ← divide 4 by 2 first
2
3 + 5 × 8 ÷ 2 ← multiply 5 by 8 first
3
3 × 2 + 7 ← multiplication before addition
= 6 + 7 ← now do addition
= 13
