 - **Calculation** - If you select **Reduce row** mode, then the **Calculation** field appears. Click in the field to see a list of calculation choices you can use to create the new field. For information about available calculations, refer to [Calculation types][].
 - **Operation** - If you select **Binary operation** or **Unary operation** mode, then the **Operation** fields appear. These fields allow you to apply basic math operations on values in a single row from selected fields. You can also use numerical values for binary operations.
