Show results as
fractions or decimals
If “Fractions” is selected, KeyCalc will approximate the result to represent it in the form of a fraction.
Since the result shown is an approximation, it is not intended for complex results but rather simple
fractions of the kind: 1/2 + 1/3 = 5/6. To toggle your calculated result to display either Decimal or
Fractions press Enter with the letter G, or select show results as fraction or decimals from the context
menu.
History
The history stores all previously calculated results and formulas. To access the history, press
the previous Thumb key to go through previous calculation. To clear the history, this is done by
selecting “clear history” in the context menu. The context menu can be opened from pressing
space with M.

Creating a math
object
From the KeyMath menu, you can create visually appealing mathematical objects such as shapes,
trigonometric symbols, and many others, by selecting Create and pressing ENTER or one of the cursor
routing keys. By default, math objects are saved as .brl.
The BrailleNote Touch allows you to choose your preferred Braille code. From the KeyMath menu, select
Settings and press ENTER. Then, press ENTER on Preferred Braille Code and select it from the list. You
can choose between Nemeth, UEB, Français mathématique, Braille images, and LaTeX in Computer
Braille. Braille images means that no translation occurs and your math is just left as Braille dots in the
image object.
While typing in KeyMath, no speech or visual math is immediately available. When you have completed
an expression, press ENTER to move to a new line and the content will be visually rendered on the
screen for a sighted teacher or classmate. If you want to hear the expression you wrote, press SPACE
