## Braille Maths

I recently had to learn a special form of Braille that is used when handling maths. So that I don’t forget what I have learnt and as an aid to others I am posting the most useful points here. Below is an image that details the very handy braille sysmbols that are needed for maths and below that is a some text that will be useful to visually impaired people who cannot see the image. Sighted people can probably ignore the text at the bottom as it will probably just confuse you. Ok and now for the text.
= Dots 5,6 followed by 2,3,5,6.
+ 5,6 and 2,3,5
– 5,6 and 3,6
* 5,6 and 2,3,6
/ 5,6 and 2,5,,6
(1,2,6
)3,4,5
% 2,5 and 1,2,3,4
^ number followed by 3,4,6 and then number in lower quad eg 1,2 and 3,4,6 and 2,5,6 = 2^4
Root = 1,4,6 then a number to indicate which root then number sign then the number to find the root of. E.g 1,4,6 and 1,4 and 3,4,5,6 and 2,4 = cube root of 9. 1,4,6 followed by no number bit simply the number sign means square root.
Fraction is simply a number followed by a number in lower quad e.g. 1 and 2,3 = 1/2 (half)

All clear? Good.
