[Blindmath] Performing calculations as a blind students, tips, tricks and advice for the NFB Youth Slam

Wed Jul 13 15:31:44 UTC 2011

Thanks to everyone who has contributed so far.
I agree with Steve that we mustn't get too focused on computers when
solving math problem. In fact, the natural way to solving math has
been pen and paper for all the people I have worked with and I have
had better success with certain problems by diggin up my Perkins and
using it to simplify equations.
Also braille support for math is sadly still inefficient, especially
in the refreshable braille department.
But that's a whole separate issue I don't want to take over this discussion.
Please keep the ideas coming, if you have new ones.
I will post my write up/presentation notes on www.access2science.com
(if desired) after I have given the presentation in Baltimore.
Thanks
