# Arithmetic and conditional operators

Calculated Fields for ACF supports two different classes of operators, arithmetic and conditional.

### Arithmetic operators

The arithmetic operators corresponds to the basic math operators that you are probably already very familiar with:

Operator Name Description
+ Addition Returns the sum of two numbers
Subtraction Returns the difference between two numbers
* Multiplication Returns the product of two numbers
/ Division Returns the quotient of two numbers

### Conditional operators

An expression can also contain an expression using a conditional operator. Conditional operators will return either 1 or 0 representing true or false. The supported conditional operators are:

Operator Name Description
== Equals Returns 1 when two values are equal, 0 otherwise
!= Not equals Returns 1 when two values are not equal, 0 otherwise
> Greater than Returns 1 when the first operand is greater than the second operand, 0 otherwise
< Less than Returns 1 when the first operand is lower than the second operand, 0 otherwise
>= Greater than or equal Returns 1 when the first operand is greater than or equal to the second operand, 0 otherwise
<= Less than or equal Returns 1 when the first operand is less than or equal to the second operand, 0 otherwise
