Digital Cameras Photo Reviews of Texas Instruments TI-30X IIS 2-Line Scientific Calculator

Customer Review: Good for the price
Summary: 4 Stars

I'm in college and couldn't afford buying a TI-87? or 93? (can't remember what is what) but anyways, this does the job. I'll eventually end up buying the more expensive calculators but in the mean time- I use this calculator every other day and it holds up well. I strongly recommend this product for a high school student or a beginning college student. Otherwise, if you have the extra cash, you should just invest in the more expensive texas instrument calculator to save you from having to buy two calculators!

Description of Texas Instruments TI-30X IIS 2-Line Scientific Calculator

New 2-line display. Dual power:solor and battery. View entry abd results at the same time. Edit current entry. Edit and view previous entries. Menus with functions and mode settings. Five variable memories. One and two variable statistics, results, for linear tegression, trendline. Fractions and fraction/decimal conversions. Trigonometric functions in degrees and radians.
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:

  • Two-line display
  • Relatively inexpensive
  • Handles one- and two-variable statistical calculations

Cons:

  • Weak documentation
  • Buttons wiggle a bit too much

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.
