No, Ashley made a mistake going from Step 2 to Step 3. Ashley should have multiplied 8 and 2 before dividing. The order of operations says to multiply before you divide.

Question

No, Ashley made a mistake going from Step 4 to Step 5. Ashley should have added 4 and 16 before subtracting. The order of operations says to add before you subtract.
Yes, Ashley's work is correct.

Answer 1

It looks like you're discussing the order of operations in a mathematical problem and evaluating Ashley's steps. To clarify the situation, let's go over the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

1. When determining whether Ashley made a mistake while transitioning between steps, you should first look at the specific expressions or calculations she performed in those steps.
2. If Ashley was indeed supposed to multiply before dividing (as in your first statement), then her mistake would be valid based on the correct application of the order of operations.
3. Similarly, if she needed to add before subtracting in a particular step, then your second statement would also point to a mistake.

If you provide the steps or calculations Ashley made, I can help you determine if the work is correct or where the mistakes occurred!
