Formulas can be defined in a variety of ways to perform a variety of
calculations.

Multiple operators, of different types, can be combined in different ways
within a formula. “Nesting” of operations within a formula can be employed
through the use of the parentheses. Or, a formula can consist of a single
operand, with no operators.

A first step in formula definition is to review the available operators and
operands – this information is listed in the sections “Entering Operands” and
“Entering Operators” in this chapter.

The next step in formula definition is to decide on the formula content, and
results desired from the formula – that is, determine what you want the
formula to do, based on your application requirements.

Once you have decided on the formula requirements, to define a formula, use
the formula entry keyboard, which is described in the following two sections.
