Arithmetic operators are used to combine numeric expressions arithmetically to form other numeric expressions.

The arithmetic operators (in order of precedence) are as follows:

Unary operators group from right to left, while binary operators group from left to right. Use the unary negative (-) to reverse the algebraic sign of a value.

To force a desired order of evaluation, use parentheses. For example:

is an expression in which the parentheses force the addition operator (+) to take precedence over the multiplication operator (*).
