Casio FX-85ES Plus 2nd Edition

The Casio FX-85ESPLUS features a natural display. The so-called Natural V.P.A.M. LCD allows you to enter and display fractions, square roots, and other numerical expressions in the same way they appear in your textbook. The FX-85ESPLUS easily converts between sexagesimal and decimal systems and vice versa. It performs calculations in degrees, radians, and gradians, and provides conversions from polar coordinates to rectangular coordinates and vice versa. Additionally, the calculator is equipped with a random number generator. Other highlights of the FX-85ESPLUS include prime factorization, calculations with remainders, a repeat function, 24 levels of parentheses, a memory for nine variables, and a STO/RCL key. The calculator is powered by a hybrid system of a solar cell and a battery, offers a German menu interface, and comes with a hard case.
