There isn't any way to make math on a Powerpoint slide accessible except by
having a sighted person read it aloud or otherwise convert to some form
understandable by the user.  It is essentially impossible today to write
math using any mainstream application that can be read by a totally blind
person.  It is possible, or at least very nearly possible to obtain braille
math from the Scientific Notebook application (for example see the MAVIS
work: http://www.nmsu.edu/~mavis and the Duxbury web site:
http://www.duxburysystems.com/tutorial/math.asp.

The new markup language mathML will cure this problem.  Someday.
