You may type using computer Braille, UEB, or Nemeth Braille when inserting
expressions. Press "Backspace-G" to cycle the Braille codes. Clear the
calculator with "Backspace-C". If you insert numbers or a function into a result,
the result disappears; and if you enter operators, you move to the next step. In
addition, you can keep your result in the calculator's memory, and recall it later.
You can activate the functions and operators via the calculator menu or you can
use the hot keys associated with the various functions.
13.1.1 GENERAL FUNCTIONS
To access general mathematical operations, open the menu by pressing
"Space-m or "F2" and press "Enter" on "General Functions". From the
calculation line, access the "General Functions" by pressing "Enter-G".
"General functions" is a dialog box that contains the "general function list", a
"Confirm" button, and a "Cancel" button. You can navigate the operators using
"Space-1" or "Space-4". Or, you can press the first letter of the operator you
want to access.
Select your desired operation and press "Enter" to perform it. You can also use
hot keys to quickly execute operations. Press "Space-H" for a list of hot keys in
the Calculator.
To enter negative numbers type minus (dots 3-6) and the number in
parentheses. For the percent operation, type the numbers first followed by the
percent sign. Immediately after you type the percent sign (%), the number you
have typed in is converted into a percent value.
13.1.2 FRACTIONAL ARITHMETIC
The BrailleSense can perform fractional operations such as simplifying and
multiplying fractions as well as converting fractions to decimals.
