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.

Key Features: Two-line display Fraction features Conversions Basic scientific and trigonometric functions Edit, cut, and paste entries Solar and battery powered One- and two-variable statistics

Got me from pre-algebra to pre-calcThis is probably the best calculator for middle to high school kids. I got mine in seventh grade and it was all I needed until calculus. In fact, we weren’t even allowed to use graphing calculators until pre-calc. I held off getting one until calculus, though, because my TI-30XIIS did everything i needed it to and was so easy to use.Fantastic! Don’t buy a graphing calculator!Working towards BS in physics; after years of using my TI-86 I figured it’d be rational to get a solar backup just in case I was ever in a jam for an exam. Not needing something exceptional (yet) like a TI-89 or one with graphing capabilities (that I’d actually use), I settled on this bargain calculator. After I tried it out, I did some reflection and felt absolutely disgusted that I wasted ~$100 on my TI-86 when I could’ve gotten all I needed for <$20, and of course by “need” I’m pointing towards saving time on simple time-consuming math. This calculator, meant to be my backup, replaced my TI-86. It has everything I need, is well laid out and doesn’t require batteries.4 1/2 Durable and Inexpensive!Main Points:
