#### Explanation:

In an expression which has a variety of operations, count the number of terms first.

Each term must simplify to a single number and these answers are added or subtracted in the LAST step.

In each term do the strongest operations first, - the powers and roots. Then any multiplication and division.

Brackets (parentheses) indicate when a weaker operation has to be done before a stronger one.

In the calculation, red shows what has been done in each step.
