The Arithmetic Operator

The arithmetic operator component includes the four basic arithmetic operator signs and two hash symbols:

·    + (plus)

·    - (minus)

·    * (multiply by)

·    / (divide by)

·    P (hash-plus or -add)

·    M (hash-minus or -subtract)

A hash total allows you to validate the accuracy of certain fields. For example, you can sum the numeric equivalent of a customer number field as a check on operator input.
