Following the order of operations, what does the grouped expression (4 + 3) times 7 simplify to?
A49
B28
C77
D11
Answer & Solution
Correct answer: A. 49
1. The parentheses must be simplified first, so add 4 and 3 to get 7.
2. Multiply the result by 7: 7 times 7 equals 49.
3. Without the parentheses, 4 + 3 times 7 instead equals 25, showing how the grouping symbol changes the answer.
