Question : Problem: Need a calculator with a small memory

I need a calculator that will keep a few basic equations in it after I turn it off. Would also be nice if it had a large screen that I could show the figures to someone sitting across the table. I really don't need a laptop or even a palm-pilot. That would be overkill. All the calculators today seem to have small screens. Any help much appreciated.

Answer : Problem: Need a calculator with a small memory

Get a TI 85 I think it was called.  It works really well.  You can write full programs that allow you to put in X variable (or whatever you chose), y variable, and whatever else, and then you can have it do the equation for you.

Sounds like this may be for cheating though...you want to keep equations & show them to someone across the table....hmm.
