[Blindmath] using Braille for math

Oh.

Also, \title and \author are defined, along with  \maketitle in the 
document. In the preamble, \dontcompile is randomly at the end, because 
I often forgot to change the title between assignments, so the compiler 
would fail to compile, I'd see that, and go change the title. I always 
copied from that template, so changing the title was the first thing I 
did, and if I forgot, that made me remember.

That also inserts todays date (If you want a different date, you'll have 
to use \date{bla} in the preamble or document.

Before, I wrote my problems in an improvised "calculator notation", where each line was written in a similar format to how it would appear on a scientific calculator (+ for addition, / for division, ^ for exponentiation, sqrt for square root, etc). This notation worked, but had several issues: it was ambiguous at times and hard to read for my sighted teachers.

That was, in short, a disaster; I was consistently lagging far behind my classmates when doing simple two and three digit addition and multiplication problems because of the time it took to interpret the Braille and manipulate the Math Window's tiles. I haven't used Braille for math since, using only a computer with a plain-text editor to do Algebra, Geometry, and Pre-Calculus. I have, however, used raised-line diagrams and three-dimensional models for Geometry and trigonometry.

The biggest problem with using Braille is that my teachers don't read it, so I'd have to frequently transcribe back-and-forth from Braille to LaTeX. This would be relatively painless for refreshable Braille, but less so for the hardcopy variety.

From what I've heard, Nemeth generally takes up less space to convey the same content (important for refreshable displays with limited real estate), but UEB's presentation of that content is clearer. Also, Nemeth could be replaced by the UEB math code in a few years since it's the international standard now.
