This is probably the best calculator for middle to high school kids. I got mine in seventh grade and it was all I needed until calculus. In fact, we weren't even allowed to use graphing calculators until pre-calc. I held off getting one until calculus, though, because my TI-30XIIS did everything i needed it to and was so easy to use.
The best thing:
-you can enter entire expressions and solve them. this is because, unlike earlier models, functions like sine, cosine, tangent, square root, etc. are entered before the number. for example, with other models you would punch in 45 and hit tan, and it would automatically give you the answer 1. With the 30XIIS, however, you press tan, then 1, then enter. It seems like a disadvantage at first, but when you are doing more complicated math and need to enter a whole line of info, it's a huge time-saver.
Other good things:
-You can go back and substitute other numbers into your expression. This...
I used this calculator for over 10 years before it finally stopped working, and I treated it fairly roughly (e.g.,coffe spills). I think others here have attested to the functionality of the TI-30, so I just want to emphasize that it's a tough little gadget as well. Yes, the buttons are on the small side and there is a bit of play, but this was never a major problem (although at times it slows down data entry). You can go to [...] for a good overview of TI calculators, and you can scope out one of TI's major competitors at [...]
A Little History:
This was also one of the first commercially available low-priced calculators that had two-line display and backspace to correct or edit data entry. The dual-power and scrolling display features were also once unusual. The top line (for data entry) shows up to 11 characters; you can scroll backwards or forwards up to 88! The bottom line (shows results) displays up to a 10-digit answer along with a 2-digit...

I needed a calculator for my chemistry class and I couldn't use my graphing one that I've had for the last six years so I went ahead and ordered this because it was the best selling scientific one from TI. Little did I know that it is an OLD model. I would avoid this product and go for the newer version of the TI-30! The TI-30XS is the same price and is much more usable and has more features! The buttons on this calculator are VERY loose and make data entry tricky for fast calculation. One must constantly verify that each button press has been recognized. These loose buttons are annoying if you are accustomed to quick calculations. It makes the calculator essentially unusable. I expected much more from Texas Instruments, as I really adore my 83+SE, but this is an utter disappointment.
I wish amazon had alerted me to the new version (as they do with some other products).
