    • Best calculator for engineering (electrical) you will ever own
Style: New
The TI89 is a beast of a calculator, and can do almost any math you can throw at it. Imaginary numbers in rectangular and polar form? Check. Infinity? Check. Factoring and algebra? You bet. If you are an EE or any other engineering field, you need one of these. Literally the only downside is it's not backlit. TI - if you are listening, make another TI-89 but with a backlit display!!! ... show more

    • Dont buy, warranty = 85usd service fee
Style: New
Bought it, used it twice before it stopped turning on. I contacted vendor who told me to contact Texas Instrument directly. Texas Instrument will only fix the calculator for a 85usd fee plus 8 dollar shipping. What a scam

    • Good calculator, but wrong cable was shipped - UPDATED
Style: New
Review Image by Alex Albino Alex Albino
The TI-89 Titanium is an excellent calculator. It's essential for my Calc 3 and Linear Algebra classes. Unfortunately, my TI-89 Titanium was shipped with the wrong USB cable. (Refurbished) UPDATED: November 1, 2023 - Turns out the USB port inside the calculator seemed to be misaligned with the plastic casing. After manually pushing the port into place, the USB cable connection was successful. ... show more

    • No instruction manual
Style: New
It would of been nice to have the instruction manual on how to work calculator! Other than no instruction manual it seems to be a very nice looking calculator. Just got it so haven’t been able to use it yet.

    • dont understand the question

The size of the print is too small for me to work with. I had my eye-glasses adjusted with a new prescription last month but the glasses are not helping with regard to the t-89.

    • Refurbished, not good.
Style: New
The media could not be loaded. The first week the calculator would just keep powering down for no reason. 2nd week it happened more often. The 3rd week it won’t power up. I replaced the batteries and it still did not power up. My son needs it for tests and it is useless. Not a cheap calculator either. 👎👎👎 ... show more
