Product Overview

Amazon.com Product Description With more power than most of us had in our PCs less than 20 years ago, the TI-92 Plus graphing calculator is the machine of choice for students and engineers both at the desk and on the go. It comes with over 500 KB of memory and software for working through algebra and other mathematic problems quickly and easily.

With the TI Graph Link accessory (not included), you can connect to computers and even download software upgrades. Solve linear and nonlinear equations, use the Pretty Print feature to see equations in textbook format, and work with 3-D surface graphs in real time. The QWERTY keyboard is rugged and easy to use, the 128 x 240 screen is easy on the eyes, and the calculator comes with a durable shell to protect its face when you're traveling or in the field. Additional accessories can turn the TI-92 into a mobile data-collection station, but it's just as useful at home.

Students beware: Some professors and teachers discourage, or even ban the use of calculators like the TI-92 in their classes, so make sure it's OK before you buy. Once you're set, the manual is clear and straightforward--you'll be programming in no time. Ultrageeks will love the assembly-language option, but the rest of us can get by just fine with the regular interface. The old timers might still cling to their slide rules, but anyone who needs a calculator for school or work can see why the Texas Instruments TI-92 is so popular: Its versatility, power, and portability give you the number-crunching power of a computer no matter where you are. --Rob Lightner
