[BlindMath] I'm blind! I love math! I want to go higher than high school geometry.

While I'm sure having the embossed book would be great, as I'm sure you
know, the book would be huge. It would likely be a bit expensive to emboss.
Your school might pay for it though.

If you have a refreshable braille display, you can read the book, including
the math in Nemeth on the braille display. You'll get the best quality
Nemeth if you use NVDA with the MathCAT addon. If you are a JAWS user, the
current beta of JAWS includes an option to use MathCAT, so you'll get more
accurate Nemeth if you turn that option on. Even if you don't, the Nemeth
will probably be understandable even if it doesn't meet the spec in some
cases.

Math is fun and with the work of the PreTeXt project, there is a lot more
that is accessible than there used to be. Good luck,

Neil Soiffer
