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. p 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. i--T.

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.

 cheap, but works October 24, 2008
9.99, what can you expect? In fact, this calculator has more functions than I first thought and it works fine.
Satisfied October 21, 2008
Wonderful product and the seller is top notch. Would purchase product again and agian from this seller.
Does the job.... September 25, 2008
This calculator does the job for what I need. No batteries needed and it is solar powered. Only problem I have is the cover case. It is not slide in / slide out cover cases like most calculators. It is more of a snap it on / snap it off. Other than that it does help protect it from dust and getting the screen scratched.
good buy September 3, 2008
It was sold out at our stores and I recieved it in a couple of days in the mail. Good choice
Great! April 7, 2008

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!br /br /Pros: well...it does what it's meant to do, and does it well. And at a great price, too!br /br /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 didn't work. Also, I like a slide-on cover better than the span-on cover that this calculator has. Still, I am completely satisfied with it!
