Ti 89 Titanium: As Solid As Its Name By JayZ on Jan 08, 2008 - Updated Oct 15, 2011

Math: a pain, right? Not anymore; the TI-89 Titanium cuts all of the brain-numbing, teeth-clenching frustration from the former toil that was mathematics. Any course from Algebra to Calculus would hardly be complete without the 89. Its funtions range from simple addition (of course) to automatic integration. Still, what truly makes the Ti-89 a spectacular calculator, and sets it apart from simple, mediocre tools, is its programmability. Using an easily learnable BASIC-esque language, countless features can be added to the calculator: from Hero's formula to Tetris. However, this is not to say that the TI-89 is a child's play thing. Even those not enrolled in a math class or working in a math related field, will find the utility in such a calculator. Taxes, for example, would be greatly facilitated by a downloadable TI-89 program. Personally I have used this calculator since high school and have not been let down once. It's a tool everyone should have handy.
