[BlindMath] I need some ideas and encouragement for doing braillecalculus

I highly recommend getting a tutor, it's worth it.
Also, I spent most of my time in calc copying the previous line. I worked
on a laptop rather than just a notetaker. With unicode braille on the scene
now, copying the previous line to the current place, making edits, then
converting that to la-tex seems to be the best bet. Now that nemetex is
gone, I don't know how the best way to do this would be. I had NVDA reading
most of the nemeth braille with some speech dictionaries I designed, and
with unicode braille, I could set it up so that it would only read nemeth
if it saw unicode braille. Unfortunately, I lost most of the dictionaries,
but I'd be willing to redesign them, and make it work as an addon with
unicode braille.
