Tips and hints!
Using brackets
It is not necessary to enter the final bracket.
Scrolling through previous entries
When there is a small up E or down R arrow displayed in the window you can
review previous entries and answers by scrolling up or down using the top or bottom
of the replay button.
Setting the calculator back to the factory settings
The second function on 9 allows you to clear memories and reset the calculator if
required. When you press SHIFT9 the following screen will be displayed.
Press the number corresponding to your required action then follow the screen
prompts.
Editing a calculation
Use the left or right side of the replay button to position the cursor. Pressing the
o key will delete the entry immediately to the left of the cursor. If you want to
insert a digit or operation, use the round replay button to position the cursor then
press the required button. An ‘insert‛ function is available as the second function on
o should it be required.
Order of operations
This calculator ‘knows‛ sophisticated order of operations. In addition to the usual
order of operations this calculator ‘knows‛ that in expressions like 8 ¸ 2p or 8 ¸ 2Ö2
the correct order is 8 ¸ (2p) and 8 ¸ (2Ö2). It is not necessary to include the
brackets in the key strokes.
