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.
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.
