I am redoing some high school courses in Math (I obtainedverypoor grades in secondary school, mostly because I did not care to learn anything at that stage in my life. Now I want to see about getting an under-grad degree, and what I want to do requires that I actually know math ) and I am going to have to get a graphing calculator. The course work suggests (note: suggests, NOT requires) a TI-83+, as this is what they use for examples in the lesson materials. However, I was looking at the specs, and it seems that the TI-84+ packs a bit more punch, especially in terms of processor power, but also in flash memory size. When I was in school (years ago), we did not use graphing calculators, and so I really know little about them. I am looking for suggestions on this: Would it worth the extra few bucks for the TI-84+? Or should I just grab the TI-83+?
