This calculator is pretty good, but it has its betters. The TI-89 far outstrips this calculator, especially for its "pretty print" function and its CAS (Computer Algebra System), which allows for the actual calculator to perform algebraic functions, such as solve(, factor(, expand(, csolve(, and a number of other functions. Also, variables exist only as variables, and not zero like on the 83. The 89 also allows students to perform work that would normally be done on paper, which can unfortunately prevent people from learning. For example, if you type in [(33x - 17)/14 = 195]*14, the equation becomes (33x - 17 = 2730). Then you can do ((33x - 17 = 2730))+17, and you'll get (33x = 2743), then do (33x = 2747)/33, and youll get as an answer x = 2747/33. This eliminates the need for most handwork.
But, the 89 comes with a hefty price tag, and is only really necessary for advanced mathematics classes.
The 83 is a good buy for these reasons:
1) it has a lower price (always a plus)
2) it has more compatibility and expandibility in terms of flash apps than the 89
3) the majority of teachers teach using the 83 as their example. In fact, many texts teach students to perform functions key for key, which will leave people with other calculators confused
4) it will suffice for calculus and all math classes in highschool, but the 89 is better
5) many teachers and peers will be able to help you with using the calculatory
6) the 83 is built for statistics, and therefore it is the calculator to have if you are taking statistics. Once again, the most popular statistics texts are based on the 83
7) it is more user-friendly than the other calculatorsGet more detail about Texas Instruments TI-83 Plus Graphing Calculator.
