Defining Formulas

Using the Formula Entry Keyboard

To define a formula, you would generally follow the steps listed below:

• Pick Set Formula on the Config. Results menu to access the formula

entry keyboard (see Figure 4.3, page 4–5).

• Enter your formula – Pick the keys on the keyboard which correspond to

the operators, operands, and other items (decimal points, commas,

parentheses) you are using in the formula. As you pick your formula

entries, they appear in the keyboard display:

Formula is displayed

A cursor indicates the point at which the next component entered will

appear.

• You can edit the formula as you enter it, using these edit keys:

← → Pick the arrows keys (← or→) to move the cursor to the left or right

along the formula, in order to insert a component at a particular point in a

formula, or to prepare to delete a particular component.

Del Pick the Del(ete) key to erase the entry to the left of the cursor.

Clr Pick the Clr (clear) key to erase the entire formula.

• When finished, you can pick the Ret key to save a formula, or pick the

Esc key, to restore the formula content to what it was when last saved.

When you pick the Ret key, the formula is saved, and a message appears:

You can continue to edit the formula after picking the Ret key – however,

to save the changed formula, you must pick the Ret key when finished.

Saving the formula also enables the Set Name and Formula #:

Disabled boxes on the Config. Results menu, which allow you to

enable and name the formula.
