I don't have a TI-83 Plus graphing calc, its just a TI-83 graphing calc...its a bit older, but it works just fine, so whyspend another $80- $90 when I got this for free? Will this make a big difference in getting my calc programs (mathematical) just because its not a 'plus' calc? I didn't see any sections for calculators without the 'plus' option..hope this makes sense. If not, please let me know.
Thanks!
