Works great for my high school son
Works great for my son who is in high school. Apparently whatever model the teacher uses has a few keys that are in different spots so not every function works using the exact same keys, but that has not been a problem for my son. However, if your child's teacher uses a specific model I would suggest getting that model instead so that learning would be easier for someone not as technologically inclined as my son.Works great for my son who is in high school.

Powerful calculator
This is a used item of course, so the only thing guaranteed is the calc itself. I'm loving the computer algebra system on it; taking DE and Linear Algebra this semester and never knew how much of a time saver it was. Solves for x, does operations for polynomials, factors, integrates and d/dx functions, trig extpansion, etc. Only thing thats kinda a pain is matrices, but you get used to it. Wish I had this earlier. Lot of other calcs have CAS, but this is at great price too. this website lists a lot of the features and gives you a good idea of what this calc can do and gets you started using fast as well: prenhall d0t c0m /esm/app/graphing/ti89/homescreen/Menukeys/f1 d0t html replace all the d0ts and c0mThis is a used item of course, so the only thing guaranteed is the calc itself.

Perfect for the engineering student
If your studying engineering this is a must have, It has all the features that you need to succeed. with it's build in computer algebra system it can evaluate and simplify expressions, and display them as they would be written by hand thus making test easier. It returns all of the equations for a quadratic variable making it the ideal cheat-a-lator. well worth your time and effort to learn how to use this jewel.If your studying engineering this is a must have, It has all the features that you need to succeed. with it's build in computer algebra system it can evaluate and simplify expressions, and display them as they would be written by hand thus making test easier.

PhD Mathematician in Plastic
Incredibly powerful \. You probably won't be able to use all of its functions. On the negative side: font showing date and time is incredibly small and there is no way to increase font size.

Really great calculator.
The beauty of this calculator is that it can perform basic algebraic functions for you; no more binomial expansion or tedious polynomial operations. Makes checking work very easy, and is even approved for the SAT and AP examinations. And the price is right; used with barely any wear.
