Customer Ratings & Reviews

I purchased this item for my daughter to use for her trigonometry class in college. This graphing calculator has really been a blessing to her. It’s so much easier for her to do her homework and take her exams. I am not disappointed at all.

I’ve had an 83 before which was good, but the 84 corrected a lot of things like clearer picture and adding color. I also like the fact that it has a charger and doesn’t rely on batteries anymore.

Thanks Bestbuy. .

Rechargeable battery is a good option but also the battery discharge is very low and single charge lasts for months. Good calculator for beginners as well as advanced users. Don't see any negatives for the 2 months usage so far.

This calculator is great. You basically cannot think of anything you can’t do on it and the quality is good as well. It comes with a protective case and bright screen.

My son needed a graphing calculator for his high school math classes. Its easy to use and exactly what he needed!

This is not your Daddy’s calculator! USB ports for connections to download and print-awesome! This is one of the ultimate calculators for college and high school classes. It’s so tech savvy it will be useful for years to come.

My experience with this product would be a 10 out of 10. Not only have I been able to doing multiple equations in one calculation. But has been useful in all my subjects.

[Employee of bestbuy] This calculator is very easy to use, with the ability to type quite quickly. While it is not up to the processing standard of something like the TI-NSPIRE series, it is enough to run some basic programs, and it can really help you through math classes.

This is an advanced calculator with a color screen that is clear and concise. The functions and formulas are straightforward and my kids love it. It has the worldwide reputation of Texas Instruments’ reliability.

This is my favorite calculator, the display is such good quality and the different colors for mapping graphs makes it so much easier to work with when having to look at multiple graphs at once.

Love this upgrade. Bought for my son who is a freshman in high school . It is helping him a lot during remote calculus..This is a must have for any math student in college or high school

Who knew her old expensive calculator was out of date? Her Pre-cal teacher strongly recommended a new calculator. And my daughter said this calculator was PERFECT, and the color was a great added bonus. Worth the investment, she'll take it off to college

I am in college for Accounting and have used this calculator for every class, from Algebra through Finance classes. I love that the screen is lit and in color. Makes calculations much easier when graphing multiple equations.

My son wanted this calculator and has been extremely happy with it.

For advanced calculations and graphing, this calculator has unlimited usefulness. One might think a smartphone app would be the better way to go, but you can't take a smartphone into a test. I really like the advent of the color screen for being able to differentiate graphs, it makes a difference. TI has built a good, robust product for years, so I trust this to make it through a number of years of school.

It is a great and easy to use calculator. I bought it for my dual enrollment class and because I recently took the SAT. It worked smoothly and I have yet to see any problems with the device.

This calculator is the perfect machine for upper level math at the high school level. It has all the functions needed for today's calculations. It is easy to use, very easy to read, and looks very nice. Provides a good deal of confidence.

High school requirement and second one for 2nd high schooler at home, Texas instruments is very reliable and long lasting battery. cannot go wrong with these units.

The calculator works perfectly fine for the math class that it is being used for. The battery life on it is amazing because I only charged it once and that was for the first time I had to charge it up. Overall, it is a fantastic product.
