IT'S AN ADVANCEMENT FOR ME!! |
| I ORDER IT FOR MY UNIVERSITY OF PHOENIX MATH 208/209 COURSE WHICH WILL TAKE ME TO STAT ETC. |

Very good, but not very user friendly |
| This machine is better than its predecessor TI 89, because it has more built in functions. But there is a common flaw of all TI 89 calculators, they are user unfriendly. |

Very good for Statistics and Finance too... |
I saw many reviewers for advanced math and engineering. I just want to add that it is also very good for stat and finance. It can be calculated with almost (I'm saying this because I haven't tried every single one yet ;-) every calculation with this TI-89. The plus side is that it has bigger screen and we can change any value anytime without starting over... especially good for multiple problems solving.
At first, I intendeded to purchase TI-BAII+ required by the professor but decided to trade this TI-89 Titanium with my old original TI-89. Both has flash applications for Statistics with List Editor and Finance as well as Data/Metrix Editor. For finance, you can get PV, FV, i, PMT, NPV, IRR, etc.
You can also download guide books from TI's website. This is a life saver for most business classes.... I used TI-89 from advanced algebra, pre- and calculus, fin & managerial accounting, economics, 2 statistics, and financial management... 10 courses altogether ;-) And this IT-89 costs about the same price of a business text book! Of course, you'll need to know the concepts and how to use this calculator first.
If you're wondering which one to choose between original TI89 and this new Titanium, I recommend original if you've vision problem. Original TI89 has deep purple and dark blue colors for "2nd" and "diamond" keys. This new one has very pale blue and light green keys, hard to look at if you need combination keys. SO do for "the fonts" and "alpha" key. As the manufacturer mentioned, this one has more memory and can be used USB cable.
Just a tip for the two reviewers below and others about fraction and decimal switching (.25 - 1/4 switching) :
Reviewer: MaxiMiner and Reviewer: cool dude (Stockholm)
Just use a "period" between the calculation (if you have all whole numbers) and you'll see decimals in the result without changing the "mode" you preferred. If you have any decimals between the calculations, you'll automatically see decimals. It works for every graphing calculator. I got that tip from a Math Lab Asst. in my algebra lab. |
