 Great, Standard Scientific Calculator September 4, 2007

When I was taking courses in calculus and physics, I used the TI-86 because it had more functions and was more powerful, for the kind of math that was needed.
However, the TI30XIIS is an excellent scientific calculator. It has most of the functions of a scientific calculator, with the scrollable screen that lets you check your numbers before multiplying, and perform many operations using the "Ans" function. As an organic chemist, it's the only calculator I need when it comes to doing simple chemistry calculations, which involve a lot of basic operations.
If you need to do derivates, integrals, polynomials, etc, then you should get something more powerful. If you just want a calculator to do your basic math yet allow you to check your numbers with ease, then this is a great calculator to have.

I purchased my first TI-30 in 1977 and carried in a drop holster with my slide rule, mechnacal pencils, and technical drafting pens. As the years went foward I relied on variant of the TI-30 for the latest, and every few years upgraded as I progressed in my profession.
The TI-30 has been an asset to the engineering business since the days it replaced slide rules as a portable calculator, and even today it remains one of the fastest and easiest pocket calulator to use by an engineer.
The larger beasts such as the TI-89 are fine for heavy lifting and complex transforms, but this variant of the TI-30 family is a superb buy for only a few dollars, and since the solar cell keep the power topped off so you don't have to worry about batteries.
This, and a TI-89 should both be kept on your desk, or in your briefcase. One TI-89 for the heavy lifting, and several TI-30's for the lighter duty number crunching.

 Does what it's supposed to. Nothing more. May 11, 2007

This calculator is a very basic scientific calculator. I recommend getting it if your school has a rule against graphing calculators and/or you are a cheap person who doesn't want to buy TI82 or higher or equivalent. I've never regretted buying this to replace the first one I bought for 5 dollars earlier that broke from old age.(I guess you can't expect a lot for 5 dollars postage)
 I hate the buttons on this calculator! April 9, 2007

I had to get this calculator for a professional engineers' exam (it was one of 4 approved calculators to take into the test). I've been using it to study and HATE how difficult the buttons are to press. I'm quite speedy on my Texas Instruments TI-82 but this one is painfully rigid. I originally thought it was a good idea to go with an approved calculator that resembled by TI-82 to most so I wouldn't have to relearn where all the functions are. Now, I'm second-guessing that decision and hope I'm not too fast on it during the exam so that I don't come up with wrong answers. My fingers are crossed but I really do not like this calculator so far... if you have a choice, go with another one.
