There is a Feelif, it is a new european technology, really great startup... Feelif enables you to feel shapes on phone or tablet touch screen, and you have all sorts of educational content, including for learning geometric functions... You can check about this innovation here: $1 or ask them on Facebook.

You can do any programming via a text only terminal. You will however need a linux or macos system. You can install linux subsystem for windows via the windows store. This will give you a linux terminal.

I also learned math when I had better vision. Then, once I started using screen readers, I just typed out my math in Word documents. That is how I did my college math like calculus. You end up using a lot of parentheses because the equations will be on one line instead of having a numerator on top and the denominator on the bottom for division.

I know basic braille, but I did not use it much for math because I was a lot quicker with typing and using Word documents.

I find the difference between learning math with and without Braille to be as night and day. Programming, though, I picked up mostly from examples and tutorials, which can be found in abundance via internet search.
