Great.
Great product that worked. It is missing a few 2nd Trace (calc) features that would be nice to have but is a great entry level calculator.
Great calculator at a great price.
Works great...just as well as the newer versions. I definitely recommend Texas Instrument brand calculators over other brands.
I am so happy with this item! Thanks, it's perfect.
This calculator is just like my old one that corroded.
I am especially happy to get it for five bucks. Thanks!
Texas Instruments TI-81 Graphic Calculator
Since i got it, i been using it and is very usefull for the purposes i need it, graphics and other math problems, also it was a great deal
1 out of 2 calculators?
The TI-81 calculator works perfectly, although the over abundance of stickers are annoying. Also, the second calculator received in the lot was quite a disappointment. I was atleast expecting the 4 functions to work as stated in the description. However, the TI-83 graphing calculator did not even turn on.Read full review...
Perfect!
awesome! my students are learning great with this tool, specifically linear and non linear relationships
Was in good condition!
I bought this for my math class and i like the product.. And compare to other products... i think i was cheaper..
OLD SCHOOL TECH.
This is the older model of the T,I. graphing calculater which is perfect for us older folks. Does everything that I would ever need!
ok ok ok
ok ok ok ok just fine, but this review requirement is aggravating .................................................
THIS DEVICE IS A GREAT TIME SAVER WHEN DOING SCIENTIFIC PROBLEMS.
WELL I'M NOT SURE WHICH TI-81 I BOUGHT, BUT I NEEDED AN AID TO HELP ME SOLVE A CIRCUITS PROBLEM THAT INVOLVES AN EXPLODING WIRE.
