# Operators And Literals

Special operators and literals that can be used within Databox Expressions.

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](/product-suite/admin/databox-expressions/date-expressions.md) 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;
