Editorial Review: Product Description: A calculator for science, math, algebra, trigonometry, statistics. 2-Line Display, 5 Memories Enter/delete/insert/edit individual statistical data elements Trig functions in degrees and radians Fractions and Fraction/Decimal conversions Degrees, Minutes, Seconds (for time calculations) Decimal degree conversions Common natural logarithms Reciprocals and Factorials Universal Powers and Roots Polar/Rectangular conversions Menus User-friendly keyboard with durable, plastic keys Protective calculator shield Amazon.com Review: There are many inexpensive scientific calculators on the market, but few boast the two-line display and other advanced features users get with the TI-30x IIS. The display shows the equation you are creating on the top line, and the numbers or symbols you are currently entering on the second line. Once the equation is solved, the results are displayed on the second line, and you can use the four arrow keys on the front of the calculator to edit the original equation in any way you like for a recalculation. Better still, pressing the up arrow repeatedly lets you browse through a cache of dozens of previous calculations, meaning you can look back to see the answer to a problem you solved two minutes ago, two days ago, or whenever. The device uses solar power when possible but can fall back on the internal batteries (which are included) if there isn't enough light. The buttons wiggle around a little too much and require a firm keystroke to register input, but the fact that input can be followed by looking at the output on the first line helps to cut down on mistakes. There is a shift key that doubles the functions of most buttons, and although the TI-30X IIS isn't festooned with as many buttons or functions as some other calculators we've tested in this price range, it's still very capable. There are three angle modes (degrees, radians, and grads), scientific and engineering notation modes, and even one- or two-variable statistical modes. Five variables can also be assigned to their own memory slots. The documentation is lacking, as everything is presented on a single folded sheet of paper, but Texas Instruments did manage to pack several illustrated examples on the page. The calculator comes with a snap-on cover that fits on the back of the device when you are using it. The calculator carries a one-year limited warranty. --T. Byrl Baker Pros:

Amazon.com Product Description: The new two-line TI-30X IIS with the memory retention feature retains previous entries, memory values, and individual statistical elements, and is a great value for general math, algebra, trigonometry, statistics, science, and much more. It allows you to enter, delete, insert, and edit individual statistical data elements, and displays trigonometric functions in degrees and radians. It performs common and natural logarithms, fractions and fraction/decimal conversions, and degrees, minutes, seconds/decimal degrees conversions. The calculator features durable plastic keys and a protective cover, with a quick reference card and guide for easy assistance. Average Rating:
 Rating: - good buyIt was sold out at our stores and I recieved it in a couple of days in the mail. Good choice Rating: - Great!I use this for advanced algebra I and it works great as a scientific calculator! (I still have to have a graphing calculator, but that is too big to carry around all the time.) I use this for everything I do math-wise and it works great! Pros: well...it does what it's meant to do, and does it well. And at a great price, too! Cons: I left it in my binder without the cover, and I think making it turn on and off all day long broke it. We tried replacing the battery but that ... Read More Rating:  - Simple, great calculatorThis is a great calculator for all types of math. It's simple and easy to use. Rating: - TI-30x IISI have order this calculater a while ago. I was mad that the price of shipping is not clear. Moreover, I have recieved this item a week later than it supposed to be diliver. Therefore, I wrote a letter to the customer service. They reply me right the way with a full refund on the shipping. I recived the item with good quality eventually. Rating:  - Annoying key problem.First of all: I own a bunch of different calculators from the TI line,the TI-30, the TI-84, TI-89, and I owned a TI-83 at one point. Ok, this calculator, the TI-30X IIS works, but I have an issue with the buttons. The keys feel sticky almost. Some times you push them, but the number doesn't register. You have to press with exactly the right amount of force to get it to register. And the tolerance for that force is very small. If you press down just a tiny bit to hard, or ... Read More |
