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. Ian Flanigan flan@ai.wustl.edu "You can never have too many napkins." uucp!wustl!ai!flan
