# Arithmetic operators in expressions

Arithmetic operators allow you to perform basic arithmetical functions.

Symbol | Operator | Example
+ | addition | tag1 + tag2
- | subtraction | tag1 - tag2
* | multiplication | tag1 * tag2
/ | division | tag1 / tag2
MOD, % | modulus (remainder) | tag1 % tag2
** | exponent | tag1 ** 2

##

Tip: | Be sure that any tag value you use as a divisor cannot at some point have a value of zero. Expressions that attempt to divide a number by zero produce an error at run time. To use MOD, both tags must contain integer values.
