Texas Instruments TI-36X II

The Texas Instruments TI-36X II is a solar-powered scientific calculator ideal for Algebra, Geometry, Trigonometry, Statistics, Calculator, and Computer Science. Featured is a smaller two-line display (versus the 4-line TI-34 and TI-30XS), though all the functions offered are advanced.

Included is support for one- and two- variable statistics like mean, standard deviation, linear regression, and trend line analysis; probabilities analysis via random number generation, combinations, and permutations; and full support for adding, subtracting, multiplying, or dividing fractions. Signature though is that the unit allows users to ‘recall’ previously entered equations.
