Evaluate the expression 8 [7 - 3(12 - 2) / 5].

Evaluate the expression 8 [7 - 3(12 - 2) / 5].

• A. 8
• B. 0
• C. 16
• D. 64

Answer: (A)

Follow the order of operations: evaluate inside the innermost parentheses first, then handle multiplication and division from left to right, and finally address addition and subtraction. Inside the bracket, compute (12 − 2) first, giving 10. Then multiply by 3 to get 30. Divide by 5 to obtain 6. Now the outer subtraction inside the bracket becomes 7 − 6 = 1. The whole expression is 8 times this result, so 8 × 1 = 8. So the value is 8.
