I'm deciding whether to sell my TI86, which I needed for my College Algebra class a couple of semesters ago. Do you use calculators in the nursing program and if so, what kind do you use? Are they complex, as the TI86, or are they just basic calculators? Please advise because I paid about $120 for this calculator and I'm sure that I could sell it to someone who needs it (at a reduced price, of course). Thanks!
