>No, not probably not, but that is essentially what I was saying in the >first place. So, exactly what side are you on? The 85 or 83 side? I wouldn't go to school without my 85 and 83 (leave 92 and 86 at home) just because they are inexpensive/do what I need. The 85 does graphing (some areas) and has a powerful math shell, but the 83 has lists and a better matrix editor.
