Answer:
15 ÷ (8 - 5) + 12 = 17
30 - 18 + 24 ÷ 4 = 18
7 + 11 - 4 × 2 = 10
Step-by-step explanation:
Evaluate PEMDAS for all the expressions.
15 ÷ (8 - 5) + 12 = 17
Parenthesis: (8 - 5)
15 ÷ 3 + 12 = 17
Exponents: none
Multiplication/Division: 15 ÷ 3
5 + 12 = 17
Addition/Subtraction: 5 + 12
17 = 17
30 - 18 + 24 ÷ 4 = 18
Parenthesis: none
Exponents: none
Multiplication/Divison: 24 ÷ 4
30 - 18 + 6 = 18
Addition/Subtraction: 30 - 18, then 12 + 6
18 = 18
7 + 11 - 4 × 2 = 10
Parenthesis: none
Exponents: none
Multiplication/Division: 4 × 2
7 + 11 - 8 = 10
Addition/Subtraction: 7 + 11, then 18 - 8
10 = 10
