Thanks for all of the responses I appreciate it.

As to the TI-89 what is the main difference from the 84/83?

Also I have TI-92 which I bought and then found out could not use on standardized tests. How does it relate?

One more question. Several have mentioned RPN. While I know that it works in stacks rather than brackets, how would y'all say that it compares to AOS input? And are there RPN graphing calculators?

Thanks again. I'm still kind of new to all this.
