Explanation:

To make the order of operations easier, count the number of terms first. Keep the terms separate.

EAch term must simplify to a single answer. The answers will be added or subtracted in the LAST step. You can work in different terms in the same step

Do the strongest operations first - the power and roots.

Then do multiplication and division.

If this order is to be changed, parentheses are used to indicate which must be done before the normal order.
