The person asked what is the best Scientific calculator, and not the best graphing calculator. All of you that said to go get a Ti-89 are idiots. First of all there is nothing this calculator will do that an $8 calculator will not do in HIS classes. Second he would NOT be ALLOWED to use it, my past 7 math teachers have all banned symbolic calculators from their exams (half of them will not even let us use ANY graphing calcs). Third there are no quick routes to learning math, either take the time to learn all the rules with an $8 calculator or you will not know why you are having trouble dividing by zero with your $500 super-computer talking calculator.
