Calc 158
Calc
Calc is the calculator program. It is split into two views: Desk and Scientific.
The two calculators are distinct, so you can carry out two calculations at the
same time without them affecting each other.
• The Desk view is a desktop calculator which produces a “till roll”
output. Use this calculator for general arithmetical calculations, and
those involving percentages.
• The Scientific view is a scientific calculator with 26 memories. Use
this for more advanced calculations, including those that involve
trigonometry or logarithms.
When you first use Calc, it displays the Desk calculator. Use the Desk and Sci
buttons to move between the views, or select the view you want on the View
menu.
Note! You may find the display suits your style of working better when it is
flipped’ , i.e. when the left and right sides of the screen are swapped over. Just
tap Flip layout, or use the command on the View menu.
You can perform 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.
• In the toolbar, tap the Shortcuts button 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. Use the command on the Tools menu to clear the till roll.
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 are on the Too ls menu.
