# Adding calculations
<a name="working-with-calculated-fields"></a>

Create calculated fields to transform your data by using one or more of the following: 
+ [Operators](arithmetic-and-comparison-operators.md)
+ [Functions](functions.md)
+ Fields that contain data
+ Other calculated fields

You can add calculated fields to a dataset during data preparation or from the analysis page. When you add a calculated field to a dataset during data preparation, it's available to all analyses that use that dataset. When you add a calculated field to a dataset in an analysis, it's available only in that analysis. For more information about adding calculated fields, see the following topics.
