I'd like to write a program for my TI-83 that calculates sigma notation. Unfortunately, I have no idea how (which is frustrating, because I'm usually pretty good with writing programs for my Honors Pre-Calc class).
If anyone could shed some light on the subject, or perhaps just provide me with the code for such a program, I'd be very appreciative.
