The Ti 83 Plus Graphing Calculator is an easy-to-use graphing calculator for math and science where students can graph and compare functions, as well as perform data plotting and analysis.

This calculator has everything a high school student need, for algebra, precalculus, and calculus. The 83+ is upgradable, so the need for a new calculator doesn’t arise, every few years. A graph-link can add on a TREMENDOUS amount of programs to use for Physics, Geometry, and even 3D-Graphs,

The calculator is made for Statistics, because, for some unknown reason, the TI engineers declined to put ANY suppport for stats on the 89, but the 83 is great at it. I have owned TI calculators for many years, and I have never experienced any quality or production problems with them and have never had any of them break except when treated REALLY badly, such as having very heavy, blunt objects dropped on the screen, and I do tend to use mine pretty hard.

With its clear display and fast processing, the Ti 83 Plus Graphing Calculator incorporates graphing tools for mathematics and science course work, including statistics and finance. Incredibly useful for college boards–PSAT/NMSQT, SAT I, SAT II, Math, IC, and IIC–the TI-83 is essential equipment for advanced placement courses in chemistry, physics, and calculus.

Financial functions include TVM, cash flows and amortization. Complex numbers. Enhanced data analysis includes logistic and sine regressions. I/O port with unit-to-unit link cable (included). Communicates with computers through USB connectivity kit (sold separately). Large 64×96 pixel eight-line by 16-character display. 24KB of RAM. Big 160KB archive space for storing up to 10 applications at one time. Applications can also be stored in a computer for later use or linked unit-to-unit. Four AAA batteries included.

I purchased my Ti 83 Plus Graphing Calculator in 1999 and still have it today. I have never had any problems with it and can only remember changing the batteries 3 or 4 times. I’ve even dropped it from my 2nd story balcony by accident (more like a friend knocked it off a table on the balcony) and it didn’t break. When I turned it on after it fell, my calculations were still on the screen!
