Amazon.com Product Description: For students in math and sciences, or for anyone new to graphing calculators, Texas Instruments has created the TI-83 Plus--a powerful, problem-solving tool with features for storing, graphing, and analyzing up to 10 functions. Plus, it displays graphs and evaluates tables on a split screen, allowing you to trace the graph and scroll through table values simultaneously.
The clear, readable display exhibits 12 characters and eight lines, in 64 x 96 pixels on an LCD screen. The TI-83 Plus has a pragmatic key layout and an easy-to-use graphing interface, with a simple programming language for creating conversion programs. The TI-83 Plus stores and analyzes up to 10 matrices combined with data storage in lists containing up to 999 elements per list. You can also solve equations interactively for different variables.
With the TI-83 Plus, you can view an equation, its graph, and the coordinates all at one time. Jump from point to point by entering a number. Several useful plot types are available, including scatter, box-and-whisker, XY-line, histogram, and normal probability plots. Advanced statistics and regression analysis, graphical analysis, and data analysis are readily accessed, along with features for calculus, engineering, financial, logarithm, trigonometry, and hyperbolic functions--all crucial tools for advanced analysis.

With its clear display and fast processing, the TI-83 Plus 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.
The addition of the optional TI-Graph Link (software and cable) allows you to connect the calculator to your computer, permitting the transfer of files and data between machines. The TI-83 is powered by four AAA alkaline batteries and one lithium battery for backup, with an automatic shutoff to save energy. It also comes with a hard slide cover and is supported by a one-year limited warranty. --Barbara Price
TI-83 Silver Edition Calculator This calculator is very well put together and very sturdy. The design is also easy to use and the buttons easy to press. The calculator performs all of it's functions correctly with only a couple of hookups that are usually a result of complicated mathematics. Overall this calculator lives up to the reason that schools and others alike put their trust in this machinery.
Graphing calculator it was in decent condition...it had alot of marker writings on the inside of the cover that they did not mentioned but it was able to come off...didnt come with batteries but overall it was pretty good.
TI 83 Calculator This calculator does all it is cracked up to do. I have tried using the Casio equivalent to this model and found it more difficult to use, but to be fair I have only been taught how to use the TI-83 over a period of 6 years from high school and currently in college. So if you have used this calculator before and are considering whether or not get the Casio equivalent go based on what you have the most experience with. Every math class I have ever had uses Texas Instruments.
Texas Instrument TI-83 plus I never recieved the product!!! And it has been more than a pain to contact anyone to recieve a refund!
Graphing Calculator This is the exact calculator my daughter needed for math. It came quickly and in the 'like new' condition that was expected. It is working perfectly.
