>I am considering selling it and buying a TI calculator. Which should I >buy? I'd get the TI-85. More people have it than any other TI calculator. (That means there's more programs for it.) There's no point in getting a 92, they aren't allowed anywhere- SAT's, etc. >Should I buy another calculator or just sell the Casio? Depends how much $$$ you got- I'd buy the 85.
