Defining calculation and summary fields
You define a field type as a calculation or summary field when you want the
value in the field to be the result of a formula. A formula can include values
from one or more other fields in the database, operators, functions, and
constant values.
For example, suppose you have a database that contains two number fields,
Qty Sold and Price, and one calculation field, Total. You can set up a formula
in the calculation field to multiply the values in the two number fields. Then,
each time you type values in the Qty Sold and Price fields, the formula
multiplies those values and displays the result in the Total field.
