I am mostly blind, but (especially back in college) can see enough to use assistive technology and computers. I mostly used a CCTV and my professors were mostly pretty good about sending me PDF versions of problem sets and some class materials.
I mostly used hard copies of books with magnifiers, but more and more textbooks are available online today which is good.
As for the actual math part there is something called
$1. And also check out the "See Also" on that page.
Hope this helps. And I hope others have more info because I also want to know.
