# Operators overview

Sigma supports basic operators for calculations, evaluating them in accepted order. You can use these operators when developing the conditions of Logical functions.

Sigma supports the following operators:

## Example

When calculating values, such as using the addition operator + to add two values, the result is Null if one of the values is Null.

[Column 1] + [Column 2]

If the value of [Column 2]  is Null, then the result of the entire formula is Null.

To resolve this, you can apply the Zn function to each value, to substitute 0 for Null:

Zn([Column 1]) + Zn([Column 2])

<=
Returns whether X is less than or equal to Y
>
Returns whether X is greater than y
>=
Returns whether X is greater than or equal to y
=
Returns whether x is equal to y
!=

()
Used to change the order of operations
AND
eturns whether two logical values are both TRUE
OR
Returns whether either of two logical values are both TRUE
NOT
Negate a value or expression
TRUE
Interpreted as the Boolean literal TRUE
FALSE
Interpreted as the Boolean literal FALSE
NULL
Interpreted as a null literal
