# Expressions

In the Linx Designer, Expressions can be used to define property values. When Expressions are used in this way, they are recognizable by the ‘=’ in front of the value in the Property tab. A property value of ‘1+1’ will result in ‘1+1’ at runtime while ‘=1+1’ will result in ‘2’. It works like Excel except that expressions are only resolved at runtime.

Selecting a value in scope will automatically insert an expression referencing that value. Select the [Expression Editor](https://docs.linx.software/reference/designer/expression-editor) from the property dropdown to construct more complex expressions.
