[Blindmath] Math Conversion Software

[Steve Jacobson]

Susan,

Thank you for this information.  It is why I feel that it is good to try
to build on the work and knowledge already available both to perhaps
avoid re-inventing the wheel and to understand the total complexity of
the processes involved.  Mike, I hope that you are successful, but I
think the advice to dig into some of this is very good.

Best regards,

Steve Jacobson
