Texas Instruments TI-86 Graphic Calculator

Why, oh why, does Texas Instruments not make a new TI-86 model? They have more power and functionality than the TI-83/84 line that the company is concentrating on. If you don't care for symbolic manipulation, this is the best calculator you can get.
TI has the finance apps from the TI-83 available for download on their FTP sight for this model.

Perfect condition, as stated. Fast delivery. Very friendly & helpful. I will want to recommend & do business with her again. I have her on my favorites list & have recommended her to everyone that I know.

I bought the 2 calculators for the kids school work. It was just what they wanted and needed. The price was right and the auction was spelled out exactly as they came. Totally Satisfied..

I used to have the TI-85 Plus, but it died on me. I figured let me upgrade to the TI-86. Initially, it was a learning curve to understand the ridiculous changes that were made in the TI-86. Why did they make it so difficult to figure out how to graph a function? It ticked me off in the beginning. However, once I learned how to use it, I realized that there are more functions and it is not that bad to use.

If you have used a TI-84/85 and got used to the functions and how to use them, then it will take some time getting used to the TI-86. You might get frustrated because so many function buttons have been changed to different parts on the calculator.

If you are a first time user, then it will just be the normal learning curve of something new.

I would still recommend the calculator. It does the job and more.

The product is really worth, I paid for.

Even the company stopped manufacturing this product, it is a good one of its kind...

The TI-86 is an excellent calculator. Features such as equation solver, interpolation function and unit conversion are real time savers. I am dismayed that TI has discontinued this model. After my 10 year old TI-86 suffered a fall and lost a portion of the screen I was pleased to be able to find one on E-Bay in "like new" condition for half the price of replacing it with a lesser available model.

Arrived a little later than I anticipated, but well worth it. The calculator works completely fine. Excellent buy.

Timely but the wrong product. They were willing to pay to ship it back but I just kept it because it was to much of a hassle. I was disappointed I didn't get what I paid for. Got a TI 83 Plus when I ordered a TI-86

Was never able to catch up with seller. I tried on several different occasions and the email of the seller was incorrect

I have used a TI-86 for years and for my business it is the only way to go. You can see your past four calculations, allowing you to save time and effort. This calculator has so many functions that I don't use but the ones that I do use are so valuable to me

Product was in excellent condition as promised! This is my third TI-86 for my third child. The TI-86 is no longer available in stores, so I was happy to find one on ebay for a reasonable price, and in such great condition!

This excellent calculator is a required tool for my daughter's Math Club and is used in their competitions. There is nothing we dislike about it.

it a calculator the only reason i bought it was for college. they are way to expensive so i got mine for half on ebay

I've seen many TI calculators, but the 86 is my favorite. Ya, the 89 has more features, but I find it confusing.

My son needed one for school and I really didn't want to pay the high price.I got to looking on e-bay and found one really cheap. I got it in a few days and my son loves it!!!

I thought the seller was very professional and sent the item I bid on in a timely manner. Would do business with that person again. It's nice to do business with people like that, that tries to give that extra step in pleasing a buyer.

The TI-86 has an understandable manual/guidebook, especially compared to the ti-85 guidebook.

The feature I like the most about the TI-86 and TI-85 is the conversion feature where one can convert inches to feet, meters to yards, pounds to grams. etc. There are several other conversion categories included.

This is the second best calculator I have ever owned. It has an easy to use interface and all the bells and whistles to get you through your math class.

The calculator was purchased for my son to take to college, it was a required purchase because of it's ease of use and quality of product. I would recommend this product to others.

I bought the calculator three weeks ago and was immediately impressed with the number of features available on this inexpensive calculator.Overall it is a good calculator but it is hard to use it some times. You need to study guide book to do some complicated clculations but it is wort to buy.

well everything is wrking perfect its just tht there was a witout mark on the side. tried to clean it out but it's allrite..as long as it wrks good..:)

Hello,
I bought the TI-86 like 2 months ago. However, I dislike it because it doesn't work. When I recieved it and pluged the batteries in and it didn't show any things. I can't use it from the day I receive it because it's out of order already.

This calculator will take you from high school pre-algebra all the way to upper level mathematics. As a recent collge grad, I used this in every math class that I took (pre-cal, cal, logic, stats, etc.), and it met every need. When I graduated last year, I passed this calculator down to my little sister, who is in high school algebra. It is currently serving her well.

I presume it will do the job it's meant to do. Bought it for my son who received an appointment to the US Merchant Marine Academy at King's Point. It is a required item.
