# Operators And Literals

These operators can be used to perform arithmetic and format all or parts of Numerical or Textual data:

{% hint style="warning" %}
**IMPORTANT** Do NOT use <,<=,>,>= or + when working with date values!\
See [Date Expressions](https://docs.keyfax.biz/product-suite/admin/databox-expressions/date-expressions) for specific date functions you can use for this.

### Literals

Literals are used to represent various types of data, such as numbers, characters, strings, Boolean values, and more:

| Literal Values |                  |
| -------------- | ---------------- |
| `Boolean`\*    | TRUE FALSE       |
| `Numbers`      | 0-9 +/-/.        |
| `Text`         | 'text' or "text" |

&#x20;\* = Case insensitive&#x20;
