      Chances are, you're some kind of student. You will likely be asked to graph something or put something into a matrix, or do something normal calculators don't do. You're just about to buy this one maybe because it was recommended for a class or you want to save a few $$$'S because the 89 is more expensive. But at the end of the day this calculator old! Your cellphone do a better job plotting basic graphs. You're better off getting That Casio calculator with the better LCD screen and plots the don't look like something from Minecraft. Yes you might spend a few bucks more but you'll thank me on that test when you're asked to plot something and your Casio or Ti-89 plots graphs in seconds. This 84 takes forever and a day. And if the graph is not what you wanted you will spend even more time just trying to get something that should have not taken more than 5 seconds. Overall this calculator is Slow, had bad graphics, and can't even outperform your typical iPhone calculator app.

      Let's face it, there aren't a lot of choices on the market for a graphing calculator of this magnitude. Even worse is the school gave two models of one brand as acceptable - this was one! Although expensive, it does what I need it to and more. Great financial apps, interface is fairly intuitive, and it runs on AAA batteries which are fairly cheap to replace. There is minimal difference between the models, so unless you need a specific function, the less expensive models will do what you need (unless of course your course requires a specific model). Very happy so far - now if they would just program the answers to my homework! Only complaint is that it doesn't come with a very comprehensive instruction manual - in fact, nothing more than how to unpack and put the batteries in. Highly advise hitting YouTube or Kahn Academy and watching some videos on how to enter what you need. Overall, AWESOME!

      Excellent Calculator with Graphing

      I purchased the TI 84 Plus Graphing Calculator for my son who is a college student taking a Statistics Math class. This calculator was used as an example by his instructor to get for the class and I'm so happy I bought it for him. I shopped around since its a little expensive however I was able to get it on sale at Best Buy and get my Reward points so I call that a WIN WIN PURCHASE. This calculator does everything from Math to Biology and Chemistry problems so it's an investment. I had purchased a lower priced graphing calculator however it ended up not being able to calculate all the graphing problems my son needed for his Math class so that's why I purchased the TI 84 Plus Graphing calculator since it does everything he needs and more.

      Solid Graphing Calculator

      Bought this calculator for my statistics class. It's easy to use, with a pretty intuitive keypad. The secondary functions are easy to locate, and the calculator overall has a sturdy, well-made feel to it. It's a big calculator, but not so big that I can't hold it with one hand and punch in numbers with the other. (And i have very small hands.) Downloading/uploading programs is simple. I know there are newer, fancier graphing calculators out there, but this one suits my needs perfectly, and wasn't too terribly expensive compared to other calculators.

      Required For School

      The new TI-84 Plus is a wonderful calculator. If anybody has had the TI-83 or 83 Plus, they know how easy and reliable it is. The 84 Plus is an all-around improvement on the older version and even worth the additional $15-$20. I have had it since school started and have noticed than any problem I enter, it is solved immediately upon pressing enter, or solve. The speed is a great improvement over the 83-Plus. The computer features are nice, but rarely used by myself. For anybody who is supposed to buy a TI series calculator for school, the 84 Plus us definitely the one to pick up this year and for the next few years I assume. Easy, fast, reliable, durable, and even sleek. As long as you handle it properly and use it enough, you will get all of your $110 out of the TI-84 Plus.

      Teacher Approved

      As an Advanced Algebra teacher in Williamsburg, IA, I highly recommend the TI 84 Plus Graphing Calculator. TI did a great job on the TI-82 that I bought 11 years ago when I was in high school but the improvements have been amazing. The graphs appear quicker and are easier to see and the calculator is just all around easier to use. In addition, the products available to teachers now that go along with the TI-84 Plus make it much easier on us to show the students how to use it.

      Good calculator to use because it's a standard

      Once you reach a certain level in High School, this graphing calculator is considered the standard. It's more expensive than others but the company did a good job of standardizing it with teachers and it's what they know how to teach using. Would have liked to buy a less expensive one, but I wanted my daughter to have what the teacher and other students are all using to avoid issues and ensure she is up to date with everyone else. Not worth her having to take extra time to learn something because her calculator operates a little differently.

      Good calculator for SAT

      This calculator is one of the ones required by the SAT and also my younger child's high school math classes. Another store ran out of this calculator and we had to get another one off the list. It was confusing to my child taking the SAT. We bought this one and my child felt more comfortable and will probably have a higher score on the second try of the SAT.
