HP Calculator “takes over” part of your OmniBook’s keyboard and reassigns

functions to it. You can see these functions and the applicable keys on the display of

calculator buttons—for example, pressing the Q key takes the square root of the

number in the Calc line.

Hints

Use BACKSPACE to correct a single keystroke on the Calc line.

Use DEL to erase the entire Calc line and reset it to zero.

To do simple arithmetic

1. Type the calculation in the Calc line.

2. Press ENTER (or the = key).

Your OmniBook’s HP Calculator application starts in algebraic mode, shown by the

letters ALG in the status line. When algebraic mode is active, you can type a number

into the Calc line, then type an arithmetic operator like +, then type another number

and press ENTER or the = key to see the answer.
