Plus, it displays graphs and evaluates tables on a split screen, allowing you to trace the graph and scroll through table values simultaneously.

Split screen lets you view a graph and its equation at the same time.

With the TI-84 Plus, you can view an equation, its graph, and the coordinates all at one time. Jump from point to point by entering a number. Several useful plot types are available, including scatter, box-and-whisker, XY-line, histogram, and normal probability plots. Advanced statistics and regression analysis, graphical analysis, and data analysis are readily accessed, along with features for calculus, engineering, financial, logarithm, trigonometry, and hyperbolic functions--all crucial tools for advanced analysis. With its clear display and fast processing, the calculator incorporates graphing tools for mathematics and science course work, including statistics and finance.

The included normal slide case is great for desktop work.

The TI-84 Plus is powered by four AAA alkaline batteries (not included) and one silver oxide battery (included) for backup, with an automatic shutoff to save energy. It also comes with a hard normal slide case and is supported by a one-year limited warranty.

• Calculator with built-in financial functions and statistics
• Uses Reverse Polish Notation (RPN)
• More than 120 built-in functions, including register-based cash-flow analysis
• 10-character, 1-line LCD display
• Device measures 5.0 x 0.6 x 3.1 inches (WxHxD)

The HP 12C Financial Calculator features built-in financial functions and statistics, uses Reverse Polish Notation (RPN), more than 120 built-in functions, including register-based cash-flow analysis, 10-character, 1-line LCD display, Device measures 5.0 x 0.6 x 3.1 inches (WxHxD).It has 10-character, 1-line LCD display.

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

• Robust, professional grade scientific calculator
• It has 2-line display shows entry and calculated result at same time
• Easily handles 1 and 2 variable statistical calculations
• Three angle modes (degrees, radians, and grads) and scientific and engineering notation modes
• I thas 1-year limited warranty

The Texas Instruments TI-30X IIS 2-Line Scientific Calculator features 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. The device uses solar power when possible but can fall back on the internal batteries (which are included) if there isn't enough light. 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 calculator comes with a Snap-On cover that fits on the back of the device.

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
