Customer Ratings & Reviews

Perfect for the student who is struggling with Algebra 2. We used this calculator for factoring, graphing, and several other sections in the Algebra class and it was very helpful. This was an extremely beneficial purchase.

Just got it. It seems to work for what i need it. Now if i can put it to practice and learn how to use it.

This calculator is exactly what I needed for college math. I previously had the TI-83 and that is a great calculator but this one goes a couple steps ahead with a color screen! This may seem like no big deal but the color comes in handy when you need to graph multiple things at once, because you can clearly see which is which when they’re different colors! It also charges through USB which is nicer for me than changing out batteries. It is super easy to use and there are all kinds of tutorials on YouTube and other places to show you all of the things it can do beyond simple math. The functionality of this thing is incredible! I would recommend it to anyone going into any sort of advanced high school or beyond math, and you probably won’t ever need anything else!

I got this calculator for college math. My daughter is also taking it in high school.

This graphing calculator is fast and holds a charge for a very long time. Programing and graphing are also easy.

I needed it for class & Best Buy offered price match, so I was able to pick it up in store for a great deal. I like that it has a rechargeable battery and that it’s in color. So far has been working great for my needs.

I needed this for school. It has helped me with Trig and Calculus. If you have to graph by hand, this confirms that it was calculated correctly. Take out the frustration of math and get this. It is a must-have for all students.

Kids needed it for High School and College needs. Best BUY matched Amazon and using rewards made the deal sweet Plus gave more warranty then Amazon.

[Employee of bestbuy] I love this product. Have used this before and wanted to buy one. Using the Best Buy app makes everything easier.

Best on the market. Decent size, great battery, color display. What else needed, NONE!!!. A must buy for the school.

I was recommended to get the TI-81, which is discontinued. This has color and a rechargeable battery. Kind of expensive but worth it when you really read the manual to unlock the potential.

This works fast at graphing problems. Figuring slopes to sine and cosines is nothing for this. Easily programmable and you pre stage many custom equations. A must for any high school or college math or engineering student. So. Is at NC State in engineering and uses this all the time.

If you are looking for a calculator then this is the one! It is very amazing! I love how it is electric and it is super easy to charge. It functions perfectly, and has great battery life.

Being an engineering student, it's a necessity for a great calculator. Great purchase and love that i dont have to replace batteries. I just charge my calculator up lol

My soon needed a graphing calculator that was also on the approved list for the SAT. This is the calculator that is also used by all the math teachers at his school. He loves it, and it works marvelously. Never had an issue!

Decided to take a statistics class in college and needed a calculator like this. It's simple to use and the battery life is great. A few of my classmates have the older version (TI-83) and it seems that the TI-84 is a little more user-friendly

Excellent calculator, or has pretty of functions, made high school math way easier. Pretty good battery life.

My daughter needed this for school and used it taking her SATs. She said it really helped and is easy to use. My only complaint was the price, but Best Buy had it the cheapest. It's a lot of money for a calculator.

Does what I type in and does pemdas I’m pretty sure

Purchased this for my daughter to use in school. I’m happy that she will be able to use this in high school as well since it is a little expensive. Still works great after almost a year.
