Looks like a long term and short term strategy is necessary… of course, just like a 000 - 999 system will take time to set up, you can’t just use braille tomorrow. I wouldn’t try and use it for an upcoming test.
Just FYI… the K, g, x, and y in the above formula are the same as in regular braille and Greek letters can be just as easily derived. If you happen to do blindfolded Rubik’s cubing you can also use the images for the alphabet letters in your speffz system.
Might want to cross read some of the braille links I have in the original post to avoid some common pitfalls. Just to clarify, it’s NOT “my method” as far as math… there have been lots of people over the years establishing this standard.
You could look at why they’ve changed certain things over time because things were ambiguous before. Maybe if you want it for physics only, your own system might be of advantage.
