It is somewhat similar to the TI 92 graphing calculator; however, it is definitely not the best source for graphing specifically. It has nice 3-D pictures but I usually use other sources online for graphing problems. If a graphing calculator is what you're looking for, I would get a newer model because this calculator is better for solving difficult equations and have step by step instructions to solve them. My primary reason for purchase was for assistance in my calculus 3 class.

This calculator does have some physical constants programmed into it, but I can't tell you which ones because I returned mine to Amazon due to the mixed up keys that I mentioned in my review. I ended up getting an older HP from Ebay instead, since I've had my other HPs for so long without any problems, and all the new calculators I've tried are junk. I think the manual for this calculator can be downloaded from the Sharp website and it should have a listing of the constants in it. Note that the quality control on these is terrible and the warranty is useless, but it is inexpensive. If you do decide to get one make sure that the keytops on your calculator match the ones in the photos - some on mine were mixed up (read my review) and I'm sure it isn't the only one like that. I was a physics major back in the early 90s, and I had a laminated card that fit in my 3-ring binder with about every constant you'd ever need on it - more than is in any calculator. I don't know if they still make those, but that might be a better route - and you could certainly make one yourself. Yes, you have to punch them in the calculator manually, but that's no big deal. Trust me, after you do that enough times you will end up having a bunch of the constants at least partially memorized, and that can be a huge help on exams, oral comprehensives, lecturing, etc.

Dear Donna, I had a previous one for ten years which got lost in transit. I'm not sure if new one is same, but it looks and performs identically. Keep smiling!

Sorry I just got home from vacation. I only travel with an Ipad. On your screen there is a square that says calculator. You can use the numeric numbers there. My son owns his own technology business and when he gets time he will remote into my lap top and show me. In the mean time I use the numbers on top row. I will keep your email and get back to you. My son says there should be a key that locks and unlocks the numbers. I have not been successful yet.Peggy M Woodard

Don't buy this model. It is outdated by more than 10 years. The main difference is the quantity of memory. Titanium supersede it 10 years ago and costs much less. The colors shown on the photo are not actual. Buy a Titanium for +/- $120. Titanium does everything for algebra, including inequalites, nth root, log, Ln, solves systems of several variables, matrices, integral, derivatives. It is really a dream. I had to return it and got a TI-89 Titanium. To have it clear, go to TI site.

If by "age," you mean whether it's 83, 84, 86, and so on, then yes, it is important.Each model has some different features and/or functions, so it is better to know something about the graphing calculator you're buying. If it is your first time buying a graphing calculator, ask for recommendations from some people who use them.I recommend this TI83 plus. It is allowed in testings, you will also be able to use it for college algebra, calculus, and so on.I hope this helps.

According to HP, the Platinum editition is 6X faster than the regular one. While this might be true, it is however not worth to pay 50% more. The traditional one exceeds my expectations anyway. After all, at least for myself, an average user of this calculator would not notice the speed difference under normal circumstances. So, my suggestion would be, stick to the older one and save about $23.

Yes it is a very good calculator...I use this calculator for college all the time..I love it...but it is not in common use teachers and most don't know how use it...they only know the a Texas brands most likely...you might have to learn how to use it on your own...but it is not that hard to grasp ...just watch simple YouTube videos about it...this calculator is simply amazing

the latest version of this calculator uses a single lithium rechargeable via a standard USB connector to charge it. however the owner manual for this calculator depicts 4, AAA batteries along with a CR2032 for backup. The newer model though only sports that one lithium. If the one you have or intend to have still uses the legacy battery system for this entire TI programmable line you should use AAA lithium's rather than alkaline. don't use ni-cad or ni-mh. finally, the single lithium rechargeable lasts a long time... AND the calculator even sports a battery monitor. Personally THIS is the battery system I'd be looking for and not the legacy type. the latest version of this calculator uses a single lithium rechargeable via a standard USB connector to charge it. however the owner manual for this calculator depicts 4, AAA batteries along with a CR2032 for backup.

My vote is for the h/p Prime. I tried the TI-nspire, similar to the Casio in terms of buttons and general layout, but found the Prime to be easier to use as a calculator. Other than raw programming power (the Prime will win this race, I think), the Prime is designed like a calculator: all the frequently used functions are on keys and that speeds up both calculating and programming. Keys on a calculator use less power than a touch screen, last way longer and in the case of h/p, are really dependable. If your initial purchase is for education, I think the Prime will be a calculator you will keep for use at work. My vote is for the h/p Prime.

I am looking into purchasing another. My globe lasted 5years. Manufacters have stop making them, so it must be a design defect. Others have complained that theirs lasted one year or shorter. I am use to it and miss it. But realisticly speaking I do not want to purchase something that is not reliable. I do not have the instructions around, but will look for them and let you know. I am told you can download the manual. Check out those on sale on e-bay. That't where I found out about downloading the manuel.

It work excellent, it makes any calculus you need, include programming in TI-Basic that it´s very usefull. I´m very happy with my TI Nspire Used buy in Amazon for less $30.

Yes, mine keys on the old one did disappear. I have only had this new one for a few months, and it is a huge improvement over the old one in general, but I don't know yet how long the letters will last. I am hopeful!

I returned this item because the photo when I ordered was different from this calculator, which is the one I received. You know, I just can't remember if it will hold a constant. I also have had a hard time finding a calculator that will hold a constant for calculating percentages. I want to be able to enter the percentage and 'times', and then just keep entering a number and hitting 'equals'. That function, as well as a separate Clear and Clear Entry key are my two requirements, and almost impossible to find any more. Sorry I can't be of more help.

not sure, but curious why you are buying such a ancient calculator (maybe by force??) ick... I would never go back to the 84 since the release of the nspire cx or even the hp prime.

I was disappointed with the keyboard, it had several bad keys and poor touch. My suggestion would be to look for an older IBM model M keyboard on Ebay. The old Model M's will last forever. The one I am typing on now is over 15 years old. If your PC needs USB for the keyboard, there are adapters available from Cyberguys, www.cyberguys.com.

Casio is much more intuitive Find Ti relatively clumsy. However many courses are wedded to Ti. Ti is a little faster but you would need to be very impatient to notice. Have a look at HP prime, lightning fast, cheaper, more powerful but not really tailored so well to education as the other two are and a steeper learning curve.
