Texas Instruments? TI-89 Titanium Graphing Calculator 4.6 5 9 14
Great Fast delivery, cheaper price October 5, 2013
Excellent graphing calculator I love the TI-89 Titanium. For a while, I was considering a cheaper alternative, but I'm glad I shelled out the extra money for this superior product. It's capable of so much, if you take the time to learn how to use it. It's not as intuitive as the TI-83 and 84 were, but it's not impossible to learn; once you do learn to utilize this calculator's capabilities, the time it takes to complete more complex mathematic functions gets drastically cut down. In essence, this is the best calculator I've ever used. It's worth the purchase and time learning to use. September 18, 2010
Best Calculator TI makes some of the best calculators and this one is the best one. Since it doesnt have a keyboard, it is usable on standarized tests like the SAT and GRE. It can do anything you can expect from a calculator. August 30, 2010
Great Calculator for AP Calc Easy to use. Powerful machine. Provides the user with many applications that will improve accuracy and save time. Very easy to enter and edit data. It's worth the price. April 5, 2010
