Amazon.com Product Description
Once you get to a certain level of math classes, a regular old calculator just isn't good enough anymore--you need a high-functioning calculator that can perform algebraic, trigonometric, and statistical problems in addition to general mathematical tasks. The Texas Instruments TI-30XA scientific calculator can do this for you. It is extremely handy when it comes to figuring tricky fractions. It can add, subtract, multiply, and divide fractions when entered in a traditional numerator/denominator format. This calculator can also do a variety of conversions, from fractions to decimals, degrees to radians to grads, DMS to decimal to degrees, and polar to rectangular. The display screen holds up to 10 digits.

For high school or college students tackling advanced math, this is a great tool (and a thoughtful back-to-school gift), and with more professors allowing the use of calculators during classes and exams, it's a necessary one. Easy to use and easy to slip into a backpack, the TI-30XA will soon become indispensable for both the serious and the striving math student. --Dana Van Nest

Customer Reviews

Terrific calculator; incredible bargain.
I'm a research scientist who uses computers both at home and at work. But I also like to have a good scientific calculator ready at hand for convenience. I prefer Texas Instruments calculators for ease of use and reliability. I keep a calculator in my bedroom, den, living room, car, and at work. Three of my calculators are TI30XAs. That's right, as a practicing scientist I find that the bargain-priced TI30XA calculator has every scientific function I need for most problems. On the rare occasions that I need more power I use a computer. It never ceases to amaze me that many of my scientific colleagues are so computer dependent that they don't even own a calculator. Whenever they're away from their computer, they're lost. But with several TI30XAs, I have a calculator handy almost everywhere I am. You can spend more for a calculator but it's hard to find one that out performs the inexpensive TI30XA for most applications.

Ok
This is a good calculator for simple calculations but I would highly reccommend the Texas Instruments TI30XIIS 2-Line Scientific Calculator. It has a two line display, which makes it easy to compare answers and formulas, and is powered by both solar and battery so it works in and out of the sun.

great calculator
For the price, it is hard to beat this calculator. I've had this model for years and it is still going strong, with no problems or even a change of battery. Numbers are easy to read and the buttons are fairly large, with second functions labeled clearly. Lots of functions, and it is easy to use for stats. I also like the fact that it has an OFF button, which many models don't have. If you need a graphing calculator, of course this will not do, but for everyday use this model is a durable workhorse that I highly recommend.
