Customer Ratings & Reviews

This was just what my grandson needed for his class. I can’t say enough about purchasing through Best Buy. When I found out he needed one, I had my daughter send me pictures of what was required for his class. I found it on the Best Buy website, sent her a picture of it and let her know it would be delivered the next day. Which was great in itself, but it gets better. She called me and asked if I could cancel my order, I asked her why. She said it is online $30 cheaper at Walmart. I said no, I did not have to cancel my order because Best Buy would price match. This is why I am a repeat customer at Best Buy, their customer service.

Got this for my Math 242 class and it is such a great tool! Easy set up and once you start to use the functions they become like second nature. Price is hefty but it definitely does help with classwork and understanding math. Battery also lasts a really long time.

Does everything I need it to do for my math classes. Worth the price for sure

It is what it is, but the color screen and rechargable battery is very nice. TI stands behind their products as well, which is nice so if you have issues with the batteries, as the first batch of 84 CE did, it was nice to not have to worry with what TI would do. Well worth the purchase.

My daughter needed a calculator for math her 9th grade year. This one was recommended my the school but the one that was a step below would have been acceptable and was the one required however I opted to get this one since she would need it eventually. The calculator is easy for her to use and the screen is very nice. The battery life is very descent. I would recommend you find a back up charger in addition to the one that you get as teens do tend to misplace things. However it does use the older charger so if you have one from an old phone that may work for you. Overall very satisfied with the purchase and I would recommend this product based on the feedback I got from my daughters use of it.

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.

I’ve owned for about a month and does everything I need it to do for college math courses. It has a long lasting charge. The color graphs are a plus.

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 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.

Great calculator. The use of color graphing is next level and makes it much easier to use and understand.

As a price match guarantee at Best Buy got the best deal at BB. My son needed it for his high school math graphing. This calculator has more functions and color graphing than the previous TI-84 plus.

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.

My daughter needed this for high school Algebra. It works great, came in good condition, and has survived many drops already! I anticipate she'll be able to use this all the way through college.

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

I got this for my daughter while homeschooling. She uses it alot. It was helpful for the higher math courses.

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

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.
