2.Perform the calculation using the numeric and mathematical symbol keys on the keyboard, just as you would with a regular electronic calculator.

To quit the Calc application, simply change to any other application by pressing the corresponding key.

To clear an entered value, press CzCE once. To clear an entire calculator operation, press CzCE twice.

Calculations are performed in the order of entry, not according to algebraic operator precedence, ie., the calculation 8 + 2 x 3 is performed as: (8 + 2) x 3 not 8 + (2 x 3). This is just as for a regular electronic calculator.

An M shown on the display indicates that a value is stored in the calculator’s memory. Press RzCM twice to clear the memory.

Press ' to erase the last digit typed.

An E shown on the display indicates an error, usually an overflow error (when no more digits can be displayed). When this happens, the calculator will usually ignore any subsequent input until the error is cleared. Press CzCE to clear the error.

Press +/– to change the sign of a displayed value.

For further information on other calculator operations, see p.124.

The paperless printer

In the basic calculator mode, only the results of a calculation are displayed. Using the paperless printer, each step within a calculation are retained for reference so you can later edit specific parts of the calculation. This allows you to change numbers and operators (+, –, x, ÷, =), and even to undo interim steps within a calculation so that you do not then have to reenter the entire calculation.

Pressing = terminates a calculation sequence, and a value entered after any of these keys has been pressed begins a new calculation.

Up to 50 steps can be stored for a calculation. (Power calculations must be carried out by successively pressing

X , as opposed to using = as in the calculator mode. Otherwise, the functions are the same as those for the basic calculator mode.)
