calculator that works sometimes
the back is badly scratched and the screen is missing a few pixles making longer numbers sometimes hard to read. The calculator was shipped with dead batteries installed and is missing rubber feet. The back has a classroom number scratched on it.Read full review

Great Calculator
I have owned this calculator for over thirty years. One of the best and easiest to use that was ever produced. I needed this one as a back up to my old one.

Adequate Capabilities
I believe this will get my son through college algebra, but it does not have the capability to do imaginary numbers, so we'll see if we end up having to get another more powerful calculator.

This product is just the Manual.
The manual is very good! It covers all aspects concerning the use of the Calculator. The other above "boxes" do not apply to this.

Not old, classic!
I have been using the TI graphing calculators since the 90s. I have used them for all levels of mathematics, statistics, physics, and finance. I have never had a problem with one that wasn't a result of a dead battery or abuse.
Other then cosmetically, there is very little difference in the TI 81 through the TI 84. TI began to add pre programmed apps which are nice, but not necessary. I tell my students to get the older model to learn on and wait to get the expensive one.Read full review

Did not work
The screen had vertical pixels that were missing so I have to guess what numbers are actually there. I know it is an old calculator but it is barely functioning. It would be a great calculator if I could see what is on the screen.Read full review

Very please with everything.
This was a gift for one of our sons and he was really happy when he opened his gift. It was the perfect gift. He is a math professor at the college level and this brought back good memories of his days when he was in college.Read full review

Disclaimer
I use the TI82 to assist in understanding concepts in Algebra. In this manner I find it to be totally adequate. The 83 and 84 are out of my price range and I find the 82, along with written aids, satisfactory without reservation.Read full review
