Question

who is correct? sallie 16 ÷ 2 × 8 = 64 brian 16 ÷ 2 × 8 = 1 options: sallie, brian, im not sure, both

Explanation:

Step1: Recall order of operations

In arithmetic, we follow the order of operations: perform multiplication and division from left to right.

Step2: Calculate Sallie's expression

For \(16\div2\times8\), first do \(16\div2 = 8\), then \(8\times8 = 64\). So Sallie's calculation is correct.

Step3: Calculate Brian's expression

Brian's result is \(1\). But following order of operations, as we saw, the result should be \(64\), not \(1\). So Brian is incorrect.

Answer:

Sallie
