Arithmetic 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. Exponentiation (^)
  3. Multiplication and division (*, /) are performed from left to right;
  4. Integer division (\)
  5. Mod is performed from left to right;
  6. Addition and subtraction (+ and -), are performed from left to right.
  7. String concatenation (&)
