Some of you have already read and responded to my post about studying for biochem (THANK YOU!!!), and now I need calculator advice. It has been ten years since I took gen chem, and I have (somewhere) an HP48g and a TI-94 (the big mother calculator with graphing, memory, and a 5"x8" footprint). If I could find my HP48g I would probably use that for class, but it is not where I thought it was (and it uses Reverse Polish Notation, which is a pain). So I am considering something else...I would prefer to not spend a fortune, but I am also not sure how intense our calculations will be. I know I need to at least do log calculations. Suggestions?
