### Arithmetic operators

Arithmetic operators allow you to perform calculations.

expression + expression    Addition. If either expression is NULL, the result is NULL.

expression - expression    Subtraction. If either expression is NULL, the result is NULL.

- expression    Negation. If the expression is NULL, the result is NULL.

expression * expression    Multiplication. If either expression is NULL, the result is NULL.

expression / expression    Division. If either expression is NULL or if the second expression is 0, the result is NULL.

expression % expression    Modulo finds the integer remainder after a division involving two whole numbers. For example, 21 % 11 = 10 because 21 divided by 11 equals 1 with a remainder of 10. If either expression is NULL, the result is NULL.
