The TI-30XIIS is Texas Instruments' two-line scientific calculator for middle school through college math and science. It shows your entry on the top line and the result on the bottom, so you can check what you typed before you commit. It handles fractions in numerator/denominator form, one- and two-variable statistics, basic trig and scientific functions, and it is approved for the SAT, ACT and AP exams. Against the TI-30XS MultiView it is simpler and cheaper-feeling, with a smaller two-line display instead of a four-line one, but it is a proven, widely used classroom workhorse that reviewers find reliable and easy to learn.

The TI-30XIIS is a scientific calculator from Texas Instruments for general math, pre-algebra, algebra I and II, geometry, statistics and general science. It is approved for use on SAT, ACT and AP exams.
A two-line display shows entries on the top line and results on the bottom line. You can review, edit, cut and paste previous entries to look for patterns. It works with fractions and mixed numbers in traditional numerator/denominator format, and it adds, subtracts, multiplies and divides them.
It also handles one- and two-variable statistics, trigonometry, hyperbolics, logs and antilogs. It recognizes π as a symbol in radian mode, and its menus let you choose settings for your calculation. Power comes from solar and battery.
