Performing field calculations is a simple way to batch update many records at once in your table. The Field Calculator works on string, number, and date fields and automatically calculates selected records if the layer or table has a selection set present.
Entering values with the keyboard is not the only way you can edit values in a table. In some cases, you might want to perform a mathematical calculation to set a field value for a single record or even all records. Field Calculator in ArcMap lets you perform simple as well as advanced calculations on all or selected records
