Using the on-screen pointer

In addition to clicking buttons and selecting menu items, you can use the

on-screen pointer to edit the numbers in the Readout bar. You can select

digits in the display and move the insertion point. For instance, if you entered

the number 124, but meant to enter 14, you could drag across the 2 and press

BACKSPACE to delete it..

Using the keyboard as a keypad

You may find it easier to use the keyboard for entering numbers. If you are

using the numeric keypad, be sure that the NUM LOCK key is on (the NUM

indicator is highlighted). Pressing NUM LOCK toggles the indicator between

on and off as does clicking the NUM LOCK button. The NtJM LOCK button

is located in the lower left comer of the screen.

Handling Error or Overflow Conditions

When the Calculator cannot perform a calculation, the word Overflow

appears in the Readout bar. This can happen if you try an operation not

allowed by the Calculator, such as dividing by zero. When Overflow appears,

clear it using one of the following methods:

• To clear an.error_

Click on the C/CE button to clear the number. This clears the error but retains

any operations in memory for the calculation in progress.

Double-click on the C/CE button to clear the number and delete all previous

operations for the calculation in progress.
