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

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

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.

HP 12c Financial Calculator (12C#ABA)

Programmable financial calculator Comprehensive instruction manual Uses reverse polish notation (RPN)

If you bought yourself a financial calculator during the 1980s, chances are it was this bad boy. Nothing has changed since its introduction--it still uses Reverse Polish Notation (RPN), is easy and versatile in programming, and has a thin, sturdy casing. Certainly, there's been newer, fancier calculators introduced since, but there's something to be said for the quality of classics.

The HP 12C's functions include all the basics--such as calculating APR, NPV, and IRR--and statistics are a snap. For students new to financial calculators, this is an excellent place to start. For the most part, the manual reads like a minitextbook, walking you through sample problems and situations followed by graphs and tables demonstrating the technique--and you can even check your results. The section on creating programs does seem to be written for the technically ignorant, addressing in detail how you could possibly benefit from using programs, but it'll still help you get the job done.

In general, it's a bit slower than newer models, just like last year's computer isn't as speedy as today's new release. On the plus side, it's just 3 by 5 inches and slips easily into a pocket. The bottom is printed with a few little cheat notes for common functions, which is nice for quick reference. The HP 12C's one-year warranty and available tech-support line offer reassurance this little workhorse will continue to be an industry standard for years to come. --Jill Lightner

Pros:

• Pocket size
• Thorough and simple instruction manual
• Competitive price

Cons:

• Calculates more slowly than modern machines
