Being a math and computer science major, I thought a more powerful calculator would probably come in handy. Simply put, this calculator can perform about any mathmatical function that I've wanted to use it for. Furthermore, when I find a function missing that I need, this calculator has sufficient memory and an easy-to-learn programming system to implement your own functions or programs. The TI 92 can perform mundane calculations that would be helpful in high school classes, but it is really intended to be used for the more complex ideas that upper level college courses make a student work with. It should be noted as well that some professors will not allow the use of this calculator on exams and the SAT and some other standardized tests definitely will not allow it. In my personal experience, I took a Numerical Methods math course which actually referred to my calculator several times and presented me with code on how to implement the complex equations in the TI 92. Furthermore, my favorite feature of this calculator is the "Pretty Print" function. When this feature is on, the calculator will print most math structures just as they would look in a math book. (derivatives and integrals are a simple example of this feature.) One negative aspect should be pointed out as well, because of the sheer quantity of features on this calculator, it can be difficult to learn how to use it quickly. The instruction manual is huge, but it does feature many helpful examples if one takes the time to read through it. Finally, the addition of the "QWERTY" keyboard is very useful and most people will probably wonder how they ever used a graphing calculator without such a keyboard. In conclusion, this calculator is powerful, but it can be overwhelming at first. It handles simple problems and some of the hardest mathmatical functions possible with ease. Therefore, in my opinion, this calculator is a perfect fit for a math major in college or a person in a mathmatically related profession. Others, would probably be better off to save the extra money and get the TI 89.

I've owned my TI-92 Plus for about a year now and I have been very pleased. I've also owned the 81, 83, and 85 but this is no comparison. If you're still in High School DO NOT buy this, buy the TI-89. This calculator is not allowed on the standardized tests and most teachers won't allow it. The 89 isn't quite as nice IMHO, but is does almost all the same stuff. 92 Plus has better graphics and also can do Geometry.

I've owned and used a TI-92 for two and a half years now as a construction engineering student at Iowa State. This calculator is unbelievably powerful and has been a great help in all types of classes. It can solve equations symbolically, solve multiple equations in multiple unknowns, do some awesome 3-D graphing of upper level calculus functions, analyze spreadsheets on information for statistical variables, pretty much anything you want. The only small gripe I have is that it does not do automatic unit conversions like the TI-86 did. So you need to look up conversions factors, oh well. This calculator is what 95% of engineering students at Iowa State use. It is indispensible.

This is a great calculator, but because Amazon does not have a category for old ti-92's, people often sell these as PLUS models. The only major differences are things Linear Algebra, upgradable firmware, and extra memory. You will want the extra memory if you write custom programs. Before buying one of these, email the seller and confirm it is a plus model, unless you dont care. Enjoy!

This is the best calc in the world. Perfect for college. It has a powerfull 12mhz 16bit processor (Motorola68000) originally used in Sega Genesis, Apple Macs ,Atari ST computer, Callus, system16 etc.. Compared to the 4bit Nec Saturn(HPs), this processor rocks. It's power makes this calc the best option. Maybe the Advanced mathematic software doesn't take full advantage of the processor, but remember that flash software allows you to upgrade your operative system.Last upgrade increased calc archive memory up to 702kb+188kb Ram.(total:890kb). You can download powerfull math programs, organizers(telephones, addresses, etc), file explorers(this calc supports subfolders), games, zippers, etc .All programs(even basic)runs very fast. You can made your own programs using TIbasic or 68000 assembly.

If you are super hung up on postfix, or, just want to crunch numbers as fast as possible, then stick with the HP. But, if you want a portable mathematics assistant, then its a no brainer. This is NOT just a calculator it is a mathematics beast. It uses the old motorola chip found in the original Macintosh's and runs a strip down version of Maple (the Canadian answer to Mathematica).

This device doesn't remove the thinking from mathematics, but handles the pesky details so that you can concentrate on the concepts. Nasty Integrations that would cost you at least a quarter hours labor can be solved in a moment by the math beast. I've used this thing in courses like calculus, diffy q's, complex variables, linear algebra, statistics, physics, chem labs (using the built in spreadsheet functionality) and more. And, if on the very rare occasions that I needed specific formulas or processes that weren't built in, the relatively easy programming made adding functionality simple.

For students requiring a lot of mathematics beyond the basic Calculus series, its usefulness cannot be overstated.

I've got a lot of scientific calculators but they are too slow(HP) or don't have too many possibilities(CASIO). SO I decided to buy the Ti 92 PLUS which has got a very big anti-glare black screen (128*240), a qwerty keyboard just like a computer!, factorisation, taylor, solve equations, diferential equation graphing,etc.. You don't have like other calculators only an approximate result, you've got a SYMBOLIC EXACT result! you have more than 800kb of memory to uograde your calculator from Internet and download applications(you need the ti-graph link $16.5) I try the mathlab student version and this calculator is best, you have pretty print just like it s written in books,a range from E-999 to E+999 and a 12 MHz processor. It does EASILY 2d, 3d and much more plots in seconds because it has got very simple menus. You also can divise the screen in two parts. It s great,only buy it you won't be disappointed.

The TI-92 Plus does the best of the TI calculators. The TI-92 regular doesn't do nearly as much as the TI-89, because it doesn't come with the advanced math software like the TI-89, But the TI-92 PLUS solves this and does everything that the TI-89 does, with Geometry and a little bit better display.

I LOVE this calculator. People who are done with math, but still have to take Chem. and Physics should still consider buying it. I bought mine after Calculus III, and use it every day for my other science based classes. At first it took some getting use to toting aroung this big huge calculator, but the benefits outweigh the size. I write notes in it, solve problems with it, and create programs. I even programed all the atomic masses in it, which saved me about 5 min. of test time in Chem. (and anyone who has taken Chem. knows that every second is valuable!!!) My only regret is that I did not buy it sooner. The 3D graphing would have helped so much in Calc. 111, and the calculus solver would have been great to double check my math. I'm not sure if they are even selling the TI-92 anymore, but if they are make sure to get the TI-92 plus. The units and constants are a lifesaver come test time. If your a nerd like me (and I'm assuming you are or you would not be looking up this calculator)who likes cool toys buy this calculator.!!!! =)

If you are a college student, or anyone who deals with math, I highly recommend that you purchase this calculator. It is an excellent tool for performing many types of calculations both in algebra and, seemingly, in calculus, although I have only used it for algebra so far. Unlike other, disappointing graphing calculators, this one permits you to use undefined variables (i.e., 'x' stands for nothing except 'x' unless you want it to, which is immensely helpful in performing algebraic calculations.) The QWERTY keypad also makes entering expressions a pleasure, rather than a chore; this is more than an academic point when you have a test with a time-limit, and hitting an 'alpha' key before typing every variable depicted with a letter (a,b,x,y, etc.) can use up precious time and maybe ensure that you don't get all the problems done. There are too many easy-to-use and incredibly convenient features in this calc to list here; but it truly is worth the hefty price tag. My only gripes are that the manual is sometimes a bit obscure (though it's easy to comprehend compared to most graphing calc manuals) and that the calc has no nthroot function that I can find, that is, to find the cube root of a number you have to enter it as x^1/3. These are very minor points, though, in a splendid product.
