Hello. Here's my guide to doing math entirely without braille. This is only an initial version, and it will be expanded and revised over time. This guide is evadible in both PDF and HTMl, and can be freely distributed as long as you keep the author info.
notes…
1. English is not my first language, so some errors are to be expected.
2. These files are as accessible as possible, still, do report issues, if you have them.
