While I was using my HP28S today, I couldn't get it to expand nor collect
expressions involving AND, OR, and NOT.  I also couldn't get it to will
not perform simplification operations, like DeMorgan's Laws.  This kinda
frustrated me.  Does anyone know of a way to get the 28S to do these
things?  If there is no simple way, is there a program around that _will_
do it?

Thanks in advance.
