General calculations

To perform a calculation in the Desk calculator:

1. Enter your calculation using the number and operator

buttons (+, -, × and ÷) on screen or the keyboard. There

is no operator precedence in the Desk view: all calculations

are performed as you type them in. So, 10+5×3=45, not

25.

2. Tap = or press Enter to get the result.

• Use +/- or the m key to change the sign of a number.

• Tap the Shortcuts button in the Toolbar to display a list of

shortcut keypresses.

• To clear the calculation line without ending the current

calculation, press C.

• To clear the calculation line and end the current calculation,

tap AC or press Esc.

The till roll keeps a record of your calculations so that you can

refer back to work you did earlier. The till roll scrollbar will

appear when the calculations cover more than one page. To

move around the till roll, use the scrollbar or the arrow keys. To

clear the till roll, tap the Clear tillroll button on the Toolbar or

use the command on the Tools menu.

You can switch to the embedded numeric keypad (orange print)

by pressing Shift + Menu.

Using the memoryUsing the memory

Using the memory

You can use the memory to store a value that you want to re-

use, or to act as a “running total”. The Memory commands can

be accessed from the Memories button on the Toolbar or the

command on the Tools menu.

• To store a number in the memory: tap Min or select the

Save in command while the number you want to store is in

the calculation line. An ‘M’ will appear in the calculator

display while there is a value stored in the memory.

• To retrieve a number: tap MR or select the Recall

command.

• To add the current number to the number in the

memory: tap M+ or select the Add to command.

• To subtract the current number from the number in

the memory: tap M- or select the Subtract from

command.

• To clear the memory: tap Min while 0 is displayed in the

calculation line, or select the Clear command.
