Great calculator for science and math. Will take my son through high school and beyond

This is the same calculator they use at my daughter’s school. Perfect!!!

I purchased two. The calculator is very handy for my twins that are in Pre-Algebra.

My daughter needed this calculator for her math class at her school. I used an ancient ancestor of this item when I was in high school. I used it in trigonometry; therefore the name "the Trigulator". I believe it is a testament to Texas Instruments that essentially the same device (with many technological improvements due to the passing of 36 years) is used three full decades later. Keep it up!!

This is an excellent calculator for both teachers and students! As a teacher, I have the CAS model. The book that comes with the CAS model is very good, if this is your first time using this calculator. It has step by step instructions. I use it in my class almost daily. It is a required calculator at my daughter's school and she has this model. She hasn't had an opportunity to use it yet, but I know she will love it for all of its capabilities. It can be plugged in to a wall outlet to charge and can also be charged via USB. You can also get updates via USB. Has a QWERTY keyboad and can be used on most standardized tests (ACT, SAT & AP Exams).

My daughter loves it! Teacher says it the only one she'll ever need

I recommend this product. Best Buy even did a price match at time of purchase.

this is an excellent calculator, I can do everything I need, I recommend it

Had to get this for my sons SAT test and it works as expected!

Very awesome calculator, complete with the required functions.

This calculator does just about everything you could wish for.

This calculator is the best on the market. I recommend this to anyone!!

I use this calculator a lot and it has helped in all of my college courses.

This calculator was very easy to use and the screen makes it easy to see.

Does literally everything I need, and saves me so much time on tedious and time consuming math of complicated engineering problems. It can handle matrices and carry out a whole bunch of linear algebra operations, so I can solve systems of equations much faster and focus on the details instead of performing 10 steps by hand and losing a sign somewhere. It makes dealing with and performing operations with complex numbers so much easier when dealing with circuits. If there is something you don't know how to do it is a lot easier to Google "how do you do such and such with the TI Nspire" than to look through the manual, there are tons of tutorial videos on how to use different functions on Youtube.

I got this my first year of college, it is a great device!

Great Calculator for anyone in school helps with all kind of math work.

Excellent calculator and more functionality plus work with the Macintosh
