I got it for my 13 yo grandson as his school required them to get a TI-83+ or TI-84 for one of their courses. So far this one has performed as expected. Texas Instruments does a good job of supporting these products, and I downloaded a lot of documentation in PDF format, and burned it to CD-ROM for him- including the 827page guidebook!! It's a rather complicated device, a computer actually that is based on the ZILOG Z-80 8 bit processor which was used in several of the early 8 bit computers, like the KAYRO back in the '80s. The processor is embedded in a lot of 'microprocessor controlled' devices today so it is tried and true technology. He says it is doing the job for him and while it is not as fancy as the newer TI calculators, with color displays, you have to remember, mathematics really doesn't require HD color to be effective-- this I know as I still do some calculating on my old trusty slide rule, but then again, I am just a little bit old-fashion!!!

The screen does work as noted but powers on strange because of the button pattern needed to hold to turn it in and the wrinkled or damaged ribbon cable to the screen is bad because of the various screen effects. But the screen effect was not noted clearly in the description and only said that it has a boot defect and you had to hold two buttons to turn it on and it doesn't turn on normally. But the description said nothing about a screen issue. Overall I'm still going to keep it to repair.

Texas Instruments produces some of the most popular and well known graphing calculators in the industry. The TI-83 plus can do most any math problem found in Algebra I, Geometry, and even some Algebra II/Trigonometry. The wide screen allows for graphing equations and multi-line functions. The graphing capabilities of the TI-83+ are a superb choice for Algebra I classes. The ability to automatically find intersections and a variety of other important components of a graph are only key presses away. The calculator has a powerful matrix editor allowing for easy multiplication, addition,...Read full review and subtraction of matrices. Division of matrices is not possible. The list editor allows for statistical analysis of data both numerically and graphically. Graphically, the 83+ can plot data in several different formats. Anyone who is familiar with the BASIC computer language can program the TI-83+ with ease. The calculator supports the use of almost every function through a program. Programs can be typed directly into the calculator, or on a computer. The TI-83+ also supports a special form of programs called Flash Applications. Flash Applications are generally quite complex, and are written in a special language on the computer. Overall, the 83+ is an excellent choice for anyone taking an Algebra course or any math class above that. The calculator does basic arithmetic, graphic, statistics, matrices, and a variety of other mathematical operations.Read full review
I bought the TI83 for a math class that required a graphing calculator. The purchase went smoothly. I was able to download a manual from Texas Instruments and begin figuring all it's features. The class textbook helped a great deal. I was also able to download a more current version of the operating system which help immensely. The base OS is a bit dull. The upgrade made the graphs much sharper and easier to read. If you get one, check the Texas Instruments website for information on the free upgrade. It is well worth it. The TI83 has been around a long time and there is much written about it. It is a work horse educational tool, but it is also a bit long in the tooth. Newer and faster calculators are out there. Which new iteration, more features are added which add to the complexity of the instrument but also add to it's utility. As a base calculator it works well and fits my needs for the time being. Many undergraduate math programs still endorse the TI83/TI84. I suspect that if you are contemplating more work in engineering or the sciences, then a more recent vintage calculator would be worth consideration.Read full review
Pros: The buttons layout are clear and have good feedback. Like and fairly large LCD gray scale screen. Have detachable clear plastic cover to protect the screen and keys. Uses 4 AAA batteries, I used the rechargeable type and last a decent period of time. Cons: Back is bare and scratches easily. All plastic and fairly bland looking calculator. A bit pricey if purchase new. Not pocketable. Overall I think this is a good value. I wouldn't pay full price though and get it at Ebay at half of the price. Fully functional and suitable for high school to college.
I will start with the dislikes. I wish i had a cover that the new calculator comes with, i purchased this specific one without it, but great deal non the less. I wish the calculator had a backlight so that low light visibility wouldnt be much of an issue. I may just be new to it, but i wish use- ability was alittle easier. Besides that, the calculator is the greatest calculator i have ever gotten. It would easily make a statistics class easier and more comprehendable than it would be otherwise(actually, ive been in statistics in the past without a graphic calculator, but you must have alot of time and dedication without it, not anywhere near practicle to attempt....) Overall, i love this piece of technology, its built ruggedly, it is built by Texas Instruments which might i add, i own products like it which have lasted quiet awhile. It will just about take the brain out of math and allow you to propel yourself into strong theories and intelectual based thinking. Its a great tool to have, i highly recomend having this (ti- 83) or the ti-84 calculators around.Read full review
This calculator is great for the upper level math classroom. I took up through AP Calculus in High school in '02 and it served my purposes as I learned along the way. Now I am in Statistics as of Fall of '08 and the calculator is not only still functioning, but still serving my mathematical needs. In a year I will be going to UF and as of now this meets the calculator requirement. Through these math classes I learned to use a good deal of the functions of the calculator, but unfortunately without the teachers I think I would have been lost. Although this calculator is very advanced it would have been difficult to learn to use with out the teachers. Who wants to read an instruction manual the size of a short novel?
The TI-83 Plus is a calculatoer i will be able to use for not only my high school classes but also in college. It was sent with batteries and an internal battery, this makes it easy on myself. The TI-83 has many features that further add convinence for me. It creates graph illustrations and simplification of multiple systems. This is a great help in understanding and learning in math and in using this calculator.
I love the TI-83 Plus.. It's my 3rd one. Used, they're pretty cheap and are great calculators. I use it mainly for inputting large calculations with many operators (+,-,/,x, etc.). It's not as 'fancy' as other graphing calculators but it still has some real good basic features like Standard Deviation, Average I use often. I'd recommend it for anyone who does basic math a lot. But you can also get applications for the calculator such as Finance, Data logging apps, even games!
Ti-83 - what can I say? This is the low-cost equivalent of the TI-84 -- all the features, just a little slower and a LOT cheaper. The TI-83/84 has been the go-to calculator for High School and college for last twenty years, and it continues to provide incredible power & value to math courses. A great machine! 'Nuff said.
