Multiple Choice

Evaluate: 3 + 4 × (2 - 1)².

Explanation:
The order of operations is being tested here. Do calculations inside parentheses first: 2 − 1 equals 1. Next, apply the exponent: 1 squared is 1. Then multiply: 4 × 1 equals 4. Finally, add: 3 + 4 equals 7. Following the rules step by step gives 7. If you skip the parentheses or the squaring, you’d end up with a different result, but sticking to the order of operations leads to 7.
