We have a contraction table named latex-access which does at least some of
that. It reads math written in LaTeX, and translates it into braille. It needs
to be used in conjunction with the latex-access package. If you look at it,
you'll see that it's actually code. It's marked as executable, so brltty runs
it rather than just looks things up in it.

I have no idea how braille math is taught in other countries. Here in North
America, the best way of representing math in braille that I myself am aware of
is what's known as the Nemeth Code.

I doubt there's any such formal rule, and can't think of any good reason not to
use multi-cell representations.
