Ti-82s are sufficient in every way
If you can get your hands on a newest-model ti82 (the most common, with the clearest display) with no screen issues, you may be set for your advanced math course. Writing programs on it is easy if anyone's interested, and is a good supplement for the occasion that its missing some features that would be introduced in later TI calculators. The battery life is ok, and it's decently fast. Nowadays i wouldnt pay more than 15 dollars for one though.

texas instrument
The case to this calculator had someone's name written on it. I try to get it off,but couldn't. I have a hard time buying things that are labeled With somebody else's name. I would not have purchased it had I known. And I wish it would've said something in the description.

A good basic calculator for a low pricepoint
Good graphing features. Easy to move from this calculator to learning how to use the newer TI-83 and 89 models. Sometimes the screens on these calculators have small 1 pixel blank vertical lines as they get older, but you can still read the displays in almost all cases.

A Familiar favorite Returns
Obviously there will not be a run on Vintage 1996 TI BAII Plus Advanced Business Analyst calculators. I had a specific need, and shopped for a specific product, and received exactly what I was looking for. Somewhere in my home lurks my own TI BAII Plus ABA calculator, but I've given up hope of ever finding it again. This is the familiar friend that took me through Capital University's Dayton Adult Degree Program in Accounting. Now that I am advancing through my ChFC designation, I needed my trusty calculator friend...but he was nowhere to be found. I purchased a new TI BAII Plus, but it's not the same calculator....almost...but not quite. There are a few functions and capabilities that are missing from the younger sibling of the TI BAII Plus ABA, now known as the TI BAII Plus Professional. Many say that those additional functions are not needed...nonetheless, I wanted to know that I had them in any event. The calculator arrived in excellent condition. Overpacked and overwrapped...it was a challenge to unwind. What I found was a beloved TI BAII Plus ABA calculator in a condition to belie it's 21 year history. I'm guessing the previous owner cared for their trusted friend as I did...prior to misplacing it. I expect to will this tool to my grandson when he reaches an age to appreciate it, and the hardy slip cover that comes with it. Now...to find the detailed owners manual that accompanied my original calculator, and I'll feel complete once again,

ti-82
Great calculator. not as fast or as good of a display as the 83, but, it take a licking. These calculators were built to last.

Great features for the price
The TI-82 is the predecessor to the TI-84 and offers a set of features almost as robust. If the keyboard isn’t enough to show what you need, search for the user guide to be sure it meets your needs.
