# 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 ](/kalipso5/developing/form/expressions/functions.md)and all the Kalipso objects from where you can retrieve values ([Global Variables](/kalipso5/developing/form/variables.md), [Controls ](/kalipso5/developing/form/controls.md)and [Local Variables](/kalipso5/developing/form/option-window/local-variables.md)). To use any of these items you just have to double-click it and it will be automatically added to the Expression. ### Examples: * *Example 1* 4 \* 2 / 3\ **Result:** 2 * *Example 2* 4 \* (2 / 3)\ **Result:** 2.666 * *Example 3* 1 + 1 \* 2 / 3\ **Result:** 1.333 * *Example 4* 1 + ((1 \* 2) / 3)\ **Result:** 2.5 --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
