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
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.

 best all around calculator for beginning level algebra October 30, 2009
GHS (Gladstone, OR)
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.
 Serviceable but ugh October 25, 2009
Andrew Chase
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 out a lot.
The 30XIIS is for the most part a good value- it costs aboot $15 tops and it has two lines to look at, does logs and lns and the reverse, and basically does what you ask of a serious scientific calculator, so for that I give it 3 stars.
In terms of being a joy to use though, I guess all I can say is that I've long since spent $60 to have a calculator that does roughly the same things, at least for me, because of its weaknesses. For starters, RPN is better, end of story. So in my mind, algebraic input is a weakness. Another weakness is that unlike TI's graphing calculators, you have to painstakingly press '2nd' and then 'ans' to manipulate your current answer further. That may sound trivial, but it's very annoying when you are using it a lot.
But the thing that really makes me hate this calculator for everyday use is the lack of quality. The keys feel sloppy, but worse you can press the crap out of them and not have it register half the time. I had a TI-30XA maybe ten years ago, and it didn't have those kinds of problems.
Basically I wouldn't recommend this calculator. I would highly recommend the HP-35S, but for those who don't want to spend that much on a plain scientific calculator, I've noticed that almost all of the chinese physics grad students at my school use a casio two line scientific calculator that appears similar to the FX-300MS. If it's good enough for those guys, I think it's safe to say that it's a good product, or at least better than this thing.
Annoying Shortcomings October 20, 2009
DaveTheMovie (New York City)
The keys are hard to push.
To recall a previous answer requires using the '2nd' key.
Recalling stored numbers requires using arrows to scroll through a list.
In general, usage is inconsistent with BA II Plus.
In general, usage patterns are not intuitive.
Physical construction of calculator appear cheap.
This calculator is a relic; I wish Google would come out a competing version.

this is a good product especially if you know how to use a calculator. It will get you through your 5th-8th grade math courses and some high school.

i use this product fro not only physics but also chemistry. The Texas Instruments models are easy to use.
