Texas Instruments TI-84 Plus Graphics Calculator, Black 320 x 240 pixels (2.8" diagonal)

Always a trusty calculator. Got it for my college chemistry classes and worked great. After a whole school year still works great! Of course it’s kinda pricey, but you pay for quality.

The product interface is simple and includes only the necessary functions, so it's easy to use. It was great to see that it has all the features required for high school math classes in the U.S.

So, I bought the Texas Instruments TI-84 Plus, and let me tell you, this thing makes me feel like a wizard. Need to solve for X? Boom, done. Graph a parabola? Abracadabra! If you squint, it’s basically Hogwarts for math nerds.But let’s talk about the buttons. So many buttons. I’m convinced half of them are just there to intimidate me. Do I know what “sin” or “cos” does? No. But pressing them makes me feel like I’m hacking into the Matrix.And can we talk about the price? Who knew a calculator could cost as much as a small island? But hey, for something that can handle algebra, calculus, and probably launch a satellite if I press the right combo, it’s worth it.If you’ve ever wanted to feel both smarter and slightly terrified by math, the TI-84 Plus is your new best friend. Just don’t let it know you’re scared—it can sense fear.

Does what it needs to and works well

Acceptable for use on several different college entrance exams, the Texas Instruments TI-84 Plus is a non-CAS graph calculator capable of displaying seven graph styles, as well as performing matrix operations and business functions. It includes several apps and is ideal for most high school business, math and science courses. Included with it are a durable slide case and a connectivity cable.Typically, the best graphing calculators include both basic and advanced functions. This device offers a bit of both, letting you calculate basic equations and use business functions like amortization and cash flows. While it is a non-CAS calculator, its MathPrint functionality lets you view equations as you would in a textbook.Many applications come preloaded on the graphing calculator, including the Area Formulas, Cabri Jr. Geometry, CellSheet and Inequality Graphing. These, along with its basic and advanced functions, make the device ideal for high school courses like algebra, calculus, chemistry, and business and finance. You can also use it on AP, IB, SAT, PSAT and ACT exams.For durability, it comes with an impact-resistant case. A TI connectivity cable, which lets you transfer files to and from computers and TI devices, is also included. The cable also makes upgrading the graphing calculator's software easy. Other optional accessories, like TI-SmartView emulator software, are downloadable for use by teachers in the classroom. The emulator software works with existing projection technology in the classroom to let teachers display their calculator screen for students on a large screen, whiteboard or blackboard and up to four different representations of an equation, such as a table, graph and chart, at a time.This calculator has 24KB of RAM memory. A lithium backup battery protects the RAM memory if the device's four AAA batteries fail.This algebra graphing calculator doesn't offer the necessary advanced functions for technical college courses. However, it does help solve complex equations related to high school math, business and science, and it features a battery backup that keeps your RAM memory safe. It also comes with plenty of apps and optional software that makes it ideal for both student and teacher use.

A bit expensive for a calculator but worth it. Will help tremendously with Stats and will get used plenty with my kids school work.

got me through my college stats class very easily. good quality calculator that is always accurate. Buttons press nicely and it has a very long battery life, I haven't charged it in 4 months!

Comes with everything you need, even batteries! Quick set up 10/10.
