The Texas Instruments TI-84 Plus Silver Edition Graphing Calculator allows to 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. 21Apps are pre-loaded. For students in math and sciences, the TI-84 Plus Silver Edition 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. The optional kickstand slide case is great for desktop work. The TI-84 Plus Silver Edition is powered by four AAA alkaline batteries (not included) , with an automatic shutoff to save energy. It is supported by a one-year limited warranty.
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 Silver Edition is completely compatible with the TI-83 family. From that well-established platform, this new model adds more speed (a processor that's 2.5 times faster), an enhanced high-contrast display (eight lines by 16 characters), changeable faceplates (silver included), and a suite of 21 Apps. And with nine times more memory than the TI-83 Plus (1.54 MB of RAM, 480 KB Flash ROM), there's plenty of room for even more Apps and your own data storage.
|Includes a USB Port and cable.|
|Split screen lets you view a graph and its equation at the same time.|
|The optional kickstand slide case is great for desktop work.|
|Optional color faceplates add flare.|

The first three are basically the same.
The TI-83+ is the budget model, but it will still do just about anything mathematical that the other two will do. It'll certainly be good enough for any class that recommends a TI-83+ or TI-84+.
- The one major feature it doesn't have is Pretty Print, which shows equations and expressions as they would be written on paper, not as you would type them into a computer. That is, the TI-83+ shows 1/2 instead of a vertical fraction, and shows 2^3 instead of using superscript for the exponent.
- This calculator also comes with a few less built in apps, but only power users will ever use them.
The TI-84+ and the TI-84+ Silver Edition are even more similar.
- The TI-84+ has more memory than the TI-83+ and the Silver Edition more than the regular TI-84+, but that won't matter unless you're putting games onto your calculator.
- These both have Pretty Print, which makes the math on the screen more readable, but this was an add on feature that wasn't present in these calculators for the first 6 or so years they existed. In my opinion, the screen doesn't have a high enough resolution for it to work well, and any wide equation will scroll off the screen, which is frustrating. The feature can probably be turned off though.
As for the math capabilities for the TI-83+ and TI-84+ family:
- Perfect for any math class you'll take, until you get to calculus. It's still incredibly useful for calculus, but at that level, the TI-89's symbolic manipulation is nice to have (see below).
- Evaluates complicated expressions, solves some single variable equations, draws graphs (Cartesian, polar, parametric, sequences) and plots, calculates descriptive and inferential statistics, handles complex numbers, and I'm sure there's stuff I'm leaving off.
- See TI's website for more (they do a better job of describing its features).
In comparison, the TI-89 Titanium is a whole different level of calculator. If you buy one, you'll realize from the steep learning curve. Once you get used to it though, you'll never want to go back.
- Its huge advantage over the other 3 calculators I mentioned is symbolic manipulation. This means it can solve equations for you and take derivatives and integrals. To demonstrate what I mean, if you put 2x+3x in, it will tell you 5x. And if you put in arcsin(.5), it will give you pi/6, not a decimal. For any class from calculus beyond, this will make your life much easier!
** The downside to this power is that this calculator isn't allowed everywhere the other 3 are, like the ACT and in many classes. It is, however, allowed on AP tests and the SAT.
- It has better hardware than the other calculators, with a higher resolution screen, faster processor, and more memory. It has always had Pretty Print, which works better than the TI-84+ with the higher resolution screen.
- It can still do everything the other 3 calculators can, plus generally a bit more.
Back to the TI-84+ Silver Edition...
As far as the actual value of this product goes, it's a perfectly good graphing calculator, but all of TI's calculators are overpriced. For example, look at similarly priced phones on Amazon (even in the unlocked section, so there's no discount from contracts) and you'll notice the hardware blows these calculators away (I'm thinking of a particular XKCD comic... :) ). To be fair, I'm sure some of what you pay for is the calculator's software (cell phones can't do advanced algebra), but do a quick search for "Casio graphing calculator" and you'll still see TI's are overpriced. Unfortunately, virtually all schools and textbooks use TI exclusively, so we're stuck with the price until something changes.
As for my final recommendation:
- If you're taking a class that's lower level than calculus, buy this calculator. It's pricey, but your teacher and textbook will know how to use it, which will help you immensely when you're learning the ropes. If you want to save a buck, the TI-83+ is a good choice too. And a TI-89 Titanium would be overkill for your needs (your teacher probably won't even be that familiar with it).
- If you're taking calculus or above, buy a TI-89 Titanium. Once you get past the learning curve, you'll be glad you did. Trust me, it's worth it. Being able to check those derivatives and integrals will save your butt more than once.
- If you're buying a graphing calculator for personal use (i.e. not school), try shopping around. There's other great calculators out there not manufactured by TI (a lot of people like Casio and HP), and they're often cheaper.
P.S. (Last thing, I promise!) The product description says it comes with a silver faceplate. It doesn't. It comes with the plain grey one (they do manufacture a metallic silver one as well, which is the one I expected).
