Multiple Choice

Evaluate 2 × (3 + 4) − 5.

Explanation:
The key idea is the order of operations: do computations inside parentheses first, then multiplication, then subtraction. Start with the sum inside the parentheses: 3 + 4 = 7. Next, multiply by 2: 2 × 7 = 14. Finally, subtract 5: 14 − 5 = 9. So the expression evaluates to 9. The parentheses ensure the addition happens before the multiplication, which is why the result is 9.
