8 Scientific Calculator.
The Scientific Calculator, KeyPlus, can be used for straightforward sums such as addition or
division, but is also capable of many more complex operations.
Calculations are displayed in your preferred Braille grade on the Braille display in either the
Nemeth Braille Code for Mathematics or the UK Braille Mathematics Notation. The desired display
format is automatically selected when you set up the Calculator Braille language as described in
5.3.10 Calculator Braille Code. Calculations are also spoken if speech is on.
The result of a calculation is displayed on the Braille display and spoken if both outputs are
selected, and either the calculation result or the complete calculation can also be inserted into a
document.
Remember that at any point, you can press the HELP key to obtain information on the options
available.
8.1 Entering KeyPlus.
You can enter KeyPlus from the Main Menu by pressing S, or from anywhere in KeySoft by
pressing FUNCTION with 5. Your BrailleNote QT restores the display to what it was when you
last left the calculator. This might be the result of a calculation or part of one you were entering.
Continue entering the calculation or, if a result is displayed, starting a new calculation clears the
calculator. To clear the calculator to zero, press CONTROL with I.
