# Arithmetic operators

You can process numeric terms in comparison expressions using the arithmetic operators:

**Operator****Meaning**- +
- Add
- -
- Minus
- *
- Multiply
- /
- Divide
- %
- Integer divide (divide and return the integer part of the result)
- //
- Remainder (divide and return the remainder--not modulo, because the result might be negative)
- **
- Power® (raise a number to a whole-number power)
- Prefix -
- Same as the subtraction:
`0 - number` - Prefix +
- Same as the addition:
`0 + number`

You can use these operators to produce an intermediate result that
you can compare with another term. For example, if the field `#6` contains
a numeric value representing an employee's annual salary, and the
fields `#15` and `#23` contain numeric
values representing the employee's annual travel allowance and annual
bonus, respectively, you could use the following comparison to select
records for employees with a combined annual payment of greater than
$100,000:

`(#6 + #15 + #23) > 100000`

For another example, if field `#45` contains the
number of sick days an employee is entitled to annually, and the field `#46` contains
the number of sick days an employee has used in the current year,
you could use the following comparison to select records for employees
who have used 50% or more of their sick day entitlements:

`(#46 / #45) >= .5`

The order of precedence of arithmetic operators is as follows (highest is at the top):

**Operator****Meaning**- + - ¬ \
- Prefix operators
- **
- Power
- * /
- Multiply and divide
- + -
- Add and subtract

For example, * (multiply) has a higher priority than + (add), so `3+2*5` evaluates
as `13` (rather than the `25` that would
result if strict left to right evaluation occurred). To force the
addition to occur before the multiplication, you could rewrite the
expression as `(3+2)*5`. Adding the parentheses makes
the first three tokens a sub-expression.
