Great for calculating.

J. Harris, Amazon
31 December 2014
  • Summary: Got this for Intermediate Algebra, still using it going into Calc. Generally pretty easy to use, but most teachers use the 84, so be prepared to do some poking around and figuring it out on your own! Also, not nearly as many "how to" videos online for this one as for the 84.

  • Summary: because of its simplicity and use of mixed mode(polar/phaser and rectangular) it is a must have for anyone in the electrical field who rather not buy an 89.

Excellent condition for being used

Javier Kienzle, Amazon
24 September 2014
  • Summary: My TI-86 from highschool/college died on me, so I bought another one here. Excellent condition for being used, this model even has a GraphLink connector to connect to a computer (in addition to the standard LinkCable input/output to connect to other calculators, which my older model only had).

Utility at its finest

Robert, Amazon
4 August 2014
  • Summary: It is a classic. I do not know why they discontinued the 85 & 86 series, but they are the most user friendly in my opinion. The 84 will get the job done, but not as well and the 89 is just not for me. I mostly do trig and some light algebra on this for work and it makes my life much easier.

Great buy

Blanko, Amazon
20 July 2014
  • Summary: I needed a replacement for my TI-86 that just died (after 16 years), and I found the same model on Amazon that works perfectly fine. The open parenthesis button is missing the paint and a few keys stick a little, but it was worth the purchase.
