Calculate the expression 7 × (4 + 3) − 5.

Calculate the expression 7 × (4 + 3) − 5.

• A. 42
• B. 46
• C. 44
• D. 40

Answer: (C)

Order of operations means you do calculations inside parentheses first, then multiply or divide, and finally add or subtract. So for 7 × (4 + 3) − 5, start inside the parentheses: 4 + 3 equals 7. Then multiply: 7 × 7 equals 49. Finally, subtract: 49 − 5 equals 44. The expression evaluates to 44. If you skip the parentheses rule, you might get a different result like 42 or 40, but respecting the order of operations gives the correct 44.
