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

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.

This calculator is hands-down the best I have ever had the honor of using. While the TI-84 Plus may not have as much space or as many pre-loaded Apps as the TI-84 Plus Silver Edition, the TI-84 Plus offers everything a high school (possibly some college) math student needs in order to successfully learn and solve mathematics material. The TI-84 Plus comes loaded with several Apps that will make things even more convenient, such as a Probability Simulator and Cabri Jr., a great geometry app. Student looking to upgrade from the TI-83 Plus will find comfort in the fact that the TI-84 Plus is 2.5x faster and has 3x the memory than the TI-83 Plus. The TI-84 Plus is also extremely easy to hook up to your computer to transfer new Apps and updates to it using the USB port and the included USB cable. The TI-84 Plus will be a great investment for any student's education.I didn't want to purchase such a high cost calculator when there are much cheaper work arounds. However, for kids in school, college or taking college tests like SAT and ACT--this calculator is allowed to be used (as is the model below it. So, i bit the dust and purchased it.It works great. It is the standard used in schools so my daughter learned how to use and and can get help on it.The biggest thing is that most of the kids have these and many look alike so you need to mark it well to show it is yours and reduce the chance of theft. this of course isn't TI's fault--but it is good to know.The ti 84+ (this model) has mathprint (stacked fractions and symbols) and a USB cable. TI-83 doesn't have this. Also, i understand that this is faster than the 83. The silver edition os TI 84+ has spreadsheets and SAT/ACT test prep included. That may make it worth the increased price, but I didn't know that until I had already purchased this one.The Memory ROM/RAM between the models are:160K/24K on TI83480K/24K on TI84 Plus1.5 MB/24K on TI 84 + Silver addition (again making the silver addition probably the better value)

“Great for students! Easy to use, powerful features, and excellent battery life. Worth the investment for math and science.” ⭐⭐⭐⭐⭐

I bought this for my College Algebra Class. And I passed and got my Degree. I hate math and this one class was holding me up. It's sturdy and display screen was easy to read. Buttons were big enough to see and didn't stick overtime. I passed it on to my daughter along with the calculator study guide. Great buy

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.

Arrived quickly, as advertisedGreat product, very pleased.

The perfect tool for college math class! Just exactly what we needed. Holds up to being squished in a book bag well.

Life saver
