Order of operations

A statement can perform more than one arithmetic operation. If there is more than one arithmetic operation in a statement, they are executed according to the level of the operators: Parenthesis take precedence over all other operators; multiplication and division take precedence over mod, mod takes precedence over addition and subtraction.

Evaluate an expression in the following order:

1. Anything inside parenthesis, including functions, is done first: working from the inner-most parenthesis out;
2. Multiplication and division (*, /) are performed from left to right;
3. % is performed from left to right;
4. Addition and subtraction ( + and -), are performed from left to right.
