Product Description

Product Description

The all-purpose TI-84 Plus graphing calculator, ideal for math and science, features more than a dozen preloaded apps including functionality that encourages exploration of interactive geometry, inequality graphing, and real-world data collection and analysis. Ideal for middle school through college.

What's in the Box: 
TI-84 Plus calculator, impact-resistant protective slide case, TI connectivity/USB cable, silver oxide battery, four AAA batteries, Guidebook and free software Apps, warranty information. 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

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 am on my third TI-83+ (my first two were stolen). My brother owns an 84, and I can tell you that it offers nothing that the 83 doesn't have. Many of the preloaded apps are useless (an address book? please!), and take up so much space that the memory increase is worthless. The 84 is a continuation of TI's tendency to offer huge amounts of style with little or no substance. I prefer the 83 for its streamlined design. The one improvement is that the slip cover on the 84 does not become loose with a great deal of use, which is a problem I have encountered with my three 83s. It looks as though the USB connectivity could be a plus (for the 83, you had to buy a separate connectivity kit to connect to a PC), however, most buyers will not need to connect their calculator to their PC.

BE WARNED: What you are getting when you buy from this listing is the TI-84PTK-YELLOW Plus Graphing Calculator, not a black TI-84 Plus Graphing Calculator (as pictured and labeled in the listing). The difference is, of course, it's YELLOW. School-freaking-bus yellow and that will alert any teachers that the calculator you or your kid is bringing to class belongs to the school (even if it doesn't because you bought it here), and if that doesn't make matters worse, the imprinted words "School Property" on the face plate of the calculator will be sure to create confusion down the road.

Do a Google search for "TI-84PTK-YELLOW Plus Graphing Calculator" for a good picture of what you're actually thinking about buying here.

Amazon doesn't seem to have any issues with this as they refused to update the listing with the correct/exact product number and picture. Check out the 2nd picture of this listing as that is the actual item you are buying.

Just know what you're buying...if I'd known this was the "Student/Loaner Edition", I would've spent a little more elsewhere.

The TI-84 is a good example of where free market pricing fails. As we all know in microeconomics, the price of commodity goods and services is determined by supply and demand. This is generally a good thing as a merchant can optimally sell their wares by pricing it where the per unit revenue * purchase volume is maximized. Unfortunately, this doesn't work out very well for consumers when demand is inelastic, and especially when this is due to artificial external constraints, such as institutional policies.

What do I mean by all of this? Well, the TI-84 is in itself not a bad product. It's a sufficient graphing calculator with an established reputation and well-known format. However, the actual utility of the product and its inherent value to users does not match its price, especially relative to its alternatives. After all, the TI-89 is a far superior calculator that can do everything the TI-84 can do, and do it much better (higher resolution screen, faster processor, more memory, more programmable, wider range of software, more graphing and calculator functionality, including 3D graphs, solving of differential equations, etc.), but the TI-84 costs about as much as the TI-89. In fact, you can actually get a used TI-89 for quite a bit less than the cheapest used TI-84.

So what on earth is going on? What's the invisible hand of the free market doing? Well, it's exploiting the fact that many schools nowadays prohibit the use of the TI-89 because of a (mostly irrational) fear of cheating. The argument is that anything above a TI-84 is too powerful (i.e. it's _too good_ of a calculator), and students would be able to use it to solve test problems automatically.

After my daughter informed me she'd be taking Calculus next year, I decided to pull the trigger on the TI-84. She had borrowed a friend's TI-89 all this year for Pre-Calculus and said her teacher has the TI-84 so that it would definitely be a good choice and a little less expensive. (*It's my understanding that unless the student is going on into Engineering or similar, the TI-89 is probably overkill.)

On the package it doesn't say it's for Calculus, but after reading the Amazon Q&A, I'm confident this will work for her needs. The package I received indicates the calculator was manufactured on 12/05/14 (found at the bottom of the package). It also says 'Permitted on Testing: SAT/ACT/AP' on the box, as well as USB included and preloaded software. **Preloaded apps for: Pre-Algebra, Algebra 1 & 2, Geometry, Statistics, Biology, Physics and Business & Finance. The calculator ships with AAA batteries so it's ready to go within minutes of unpackaging the item.

Assuming it works as expected for her SATs this spring and Calculus next year, I'll be happy. Of course I'm hoping that it will carry her through college too. I do think the price on this item is high, but so is the functionality and resale value. I wish there was some consistency with the packaging of this item, but that could vary based upon the seller (Marketplace or Amazon). FYI... I purchased one sold by Amazon, and the photos are of the actual item.

This calculator should be an all-in-one solution for math and science classes from middle school through college. Especially good if your child is planning on taking honors or AP classes, SATs or looking at continuing on to college.
