The best calculator known to man

The TI-30XS MultiView™ scientific calculator is approved for use on SAT, ACT, and AP exams. It can be used in a wide variety of subjects, ranging from biology and chemistry, to geometry and algebra. This calculator is by far the most affordable, reliable, and accessible product sold by Texas Instruments. With a price tag of only $15, compared to a $100 TI-84, it's no wonder why the TI-30XS is one of the most commonly used calculators in the United States.
