Amazon.com Product Description Building on the hugely popular TI-83 Plus, which is perhaps the best-selling calculator of all time, the TI-84 Plus is completely compatible with its predecessor. From that well-established platform, this new model adds more speed (a processor that's 2.5 times faster), more memory (24 KB RAM and 480 KB of Flash ROM), an enhanced high-contrast display (eight lines by 16 characters), and more beloved Apps.

Includes a USB Port and cable.
It also adds USB on-the-go technology (cable included) that can be used to share files with other calculators or to connect to PCs or optional presentation tools.

Comes with 12 pre-loaded Apps and supports all TI-83 Apps.
Twelve Apps are pre-loaded, including Cabri Jr., CBL/CBR, Conic Graphing, Inequality Graphing, Probability Simulations, Science Tools, StudyCards, TimeSpan, Topics in Algebra 1 Chapter 5, Topics in Algebra 1 Chapters 1-4, Transformation Graphing, and more. For students in math and sciences, the TI-84 Plus is a powerful, problem-solving tool with features for storing, graphing, and analyzing up to 10 functions. Plus, it displays graphs and evaluates tables on a split screen, allowing you to trace the graph and scroll through table values simultaneously.

Split screen lets you view a graph and its equation at the same time.
With the TI-84 Plus, you can view an equation, its graph, and the coordinates all at one time. Jump from point to point by entering a number. Several useful plot types are available, including scatter, box-and-whisker, XY-line, histogram, and normal probability plots. Advanced statistics and regression analysis, graphical analysis, and data analysis are readily accessed, along with features for calculus, engineering, financial, logarithm, trigonometry, and hyperbolic functions--all crucial tools for advanced analysis. With its clear display and fast processing, the calculator incorporates graphing tools for mathematics and science course work, including statistics and finance.

The included normal slide case is great for desktop work.
The TI-84 Plus is powered by four AAA alkaline batteries (not included) and one silver oxide battery (included) for backup, with an automatic shutoff to save energy. It also comes with a hard normal slide case and is supported by a one-year limited warranty.

What's in the Box
TI-84 Plus, normal slide case, TI connectivity cable/USB cable, silver oxide battery, TI Product CD-ROM with full reference Guidebook and free software Apps, warranty information; four AAA batteries not included, alkaline recommended

5Extra protection for a expensive calculator
By Caley G
I had to have one of these for myself in school years ago, but had assumed a smartphone app would be a capable replacement these days. Apparently not. Had to purchase this one for my son. I was happy to find it through Amazon Warehouse Deals so at least there was some sort of discount and it has this nice "armored" protection on it to hopefully last through the abuse that only a teenage boy can inflict. This is the one and only graphing calculator I ever plan to purchase so I wanted it to last, and it appears as if it will do just that. It works great, and the faceplate makes it stand out from others so it won't be easily confused for someone else's. I am pleased with this purchase.
Please check "Yes" if you have found this review helpful. I rely upon others' reviews to make an informed decision anytime I make a purchase, so it is my intention to help others do the same. I welcome any questions or feedback.

4Detailed review of TI-84 Plus
By Duong Le
This is the standard for graphing calculators for high school and early college-level mathematics; the calculator is a pleasure to use.
This device is approved for SAT/ACT/AP exams.
I have been using this device for two months for Calculus 1, and it is accurate all the time.
The box includes the calculator, slide case, mini-USB cable, I/O cable, getting started guide, CD-ROM, and four AAA batteries.
The device is powered by 4 AAA batteries and a lithium battery backup to protect RAM. It has a 15 MHz processor, 480 KB of ROM for data and app storage, an I/O port, and a mini-USB port, which can be used to load apps found on the Texas Instruments official website.
Additionally, the calculator comes preloaded with 12 apps. Cabri Jr™ (interactive geometry), Conic Graphing, Inequality Graphing, and Probability Simulation are four of the most useful preloaded apps for most students.

The five keys at the top of the calculator (y=, window, zoom, trace, and graph) and their second function keys (stat plot, tblset, format, calc, and table) are conveniently placed for students to graph and view a table of x and y values for the function.
The calculator has shortcut keys for common functions such as x^-1, x^2, sqrt(x), 10^x, and e^x. It also has the mathematical constants pi and e on the right hand side of the calculator.

SUMMARY:
PROS: Good all-around graphing calculator for high school and early college-level math; apps can expand this hardware's feature set; calculator is approved for SAT/ACT/AP exams; long battery life; great user interface
CONS: This calculator is a bit expensive, considering the cost to produce this hardware; it doesn't have a computer algebra system, so it lacks features such as taking limits, finding partial and total derivatives, finding some indefinite and definite integrals, matrix operations, and advanced statistical computation. If you need a computer algebra system, you should go with the TI-Nspire CX CAS or the TI-89 Titanium Graphing Calculator; both are permitted on the SAT and the AP. If cost is a concern, get the Casio fx-9750GII Graphing Calculator, which has similar functionality to the TI-84.

1We've had several of the various TI-84 models and they work fine. Knowing how inexpensive electronics are today
By Scott
The low rating comes from the high TI pricing - not the product quality. We've had several of the various TI-84 models and they work fine. Knowing how inexpensive electronics are today, it irritates me to pay $100-150 for a calculator that really should cost no more than $30-40. I can buy an 8" Samsung Galaxy tablet these days for about $140 that has about 1000x the power and capability!! TI has has a virtual monopoly in the US school system and takes advantage of that to gouge schools and students.
