# Arithmetic Operators

Remember basic arithmetic from school? These work just like those.

Table 11-2. Arithmetic Operators

Example | Name | Result
--- | --- | ---
$a + $b | Addition | Sum of $a and $b.
$a - $b | Subtraction | Difference of $a and $b.
$a * $b | Multiplication | Product of $a and $b.
$a / $b | Division | Quotient of $a and $b.
$a % $b | Modulus | Remainder of $a divided by $b.

The division operator ("/") returns a float value anytime, even if the two operands are integers (or strings that get converted to integers).
