What our customer's say!

"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.

Read this reviews before You buy...

"TI What?", I didn't get no TI 83. The advert says TI 83, but the item is actually TI 85!??! What-a-guan???

"Great Buy", My daughter needed this calculator for her high school precal class recommended by her teacher; it's not just a caculator it is a computer that will be utilized even in college. Great value - the BEST price!

"get a manual", i recommend getting a manual... b'cuz i bought one, without the manual, and i definitely don't know how to use it... so i suggest u get a manual unless you are a geek! (unless i am too dummy =) )

"solid calculator - comparison to others", I've been using a TI-83+ for about five years. They are solid calculators with an easy-to-understand programming language. They have almost every function you need and are great for just about anything you do in high school.
However, a lot of reviews are ruling out the TI-89, saying it's hard to understand or it has functions you don't need in high school. However, the TI-89 shouldn't be entirely written off for high school math because 1) it can factor for you 2) it can solve equations for you 3) it can calculate derivatives and definite integrals. It can also express things in terms of "x" which the TI-83+ cannot. It's also a lot easier to understand, but it is very different from a TI-83+, so it's mostly just unfamiliar to users of the TI-83+.
The TI-84 and its various incarnations have become more popular for some reason. The main differences are that the TI-84 has between 2 and 3 times the processing speed of the TI-83+ and has a lot more memory. Those two attributes are only useful if you do a lot of programming, and for me the TI-83+ works just fine. The other differences are mostly cosmetic - the TI-84 looks cooler, the interface is cleaned up a little, the buttons are in curved lines rather than straight ones (something I actually find very annoying). However, the two calculators are basically the same in terms of functionality, so it's up to you. I prefer the TI-83+ myself.
If you're considering buying a graphing calculator or a scientific calculator, buy the graphing calculator. It's a lot easier to use and the large screen means you can see past entries really easily. Plus, it's a lot easier to store multiple values.
Anyway, I hope you do the right thing and get your hands on this calculator!

"Fine, just fine!", One of the finest little calculating machines ever developed.

It covers 99% of the common math spectrum, and can stand up to quite a bit of punishment. Mine's been thrown across the room, dropped, stepped on, and had the batteries put in backwards during it's 10 years of service. Still going strong, this calculator is all you need from 6th grade to college graduation.
