- Robust, professional-grade scientific calculator
- 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
- 1-year limited warranty
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.

- Great Calculator.
- My professor has the same one, the Texas Instruments TI-30X IIS 2-Line Scientific Calculator is a great calculator and very easy to use. Oh and the price is great! Other calculators go up to $80 or $90, but the Texas Instruments TI-30X IIS 2-Line Scientific Calculator is a steal almost. I highly recomend this calculator for any math student in high school or college. More reviews
- thanks for the prompt service
- thank you for your prompt service, but the calculator is a little different from what I expected. More reviews
- The "TI-30x"
- I purchased this on the recommendation of my instructor, because she said that it was simpler to use than the "TI-83/TI-89", N O T! As I write this it sits on a shelf collecting dust - will probably put it in a yard sale - with the new batteries. More reviews
- best all around calculator for beginning level algebra
- I work with high school students in Algebra I and Geometry and this is the most user friendly calculator I have found for those math levels. More reviews
- Serviceable but ugh
- I have one of these calculators because our high school chem teacher basically told us to get this one. I never use it anymore, as I have an HP 35S for that role and a TI-89, TI-84 Silver (had to get it for an algebra class), and HP-50G, which I use on tests or complicated problems where having as many stacks as I want and a very quick equation solver help More reviews
