# Numeric Expressions

Numeric Expressions return a numeric value and each part of the expression is evaluated as a numeric value. The calculation is executed linearly; no operator has priority over the others. To define priority you can use brackets (“(“). 

When editing an Expression of this type, you have available [Functions ](https://doc.sysdevmobile.com/kalipso5/developing/form/expressions/functions)and all the Kalipso objects from where you can retrieve values ([Global Variables](https://doc.sysdevmobile.com/kalipso5/developing/form/variables), [Controls ](https://doc.sysdevmobile.com/kalipso5/developing/form/controls)and [Local Variables](https://doc.sysdevmobile.com/kalipso5/developing/form/option-window/local-variables)). To use any of these items you just have to double-click it and it will be automatically added to the Expression.
