Sharp EL-531TH Calculator Green Display (digits): 10 battery-powered (W x H x D) 80 x 15 x 161 mm

For the higher school (Secondary School). In all federal states. With the Direct algebraic input logic (D. A. L.) are fractions, roots and formulas in the sequence betting community, such as the student also in the exercise book writes. With the multi-line play back function can be called up and changed or compared inputs again. This calculator is capable of displaying all in school (SEC (I) the necessary scientific functions, such as Statistics (1 & 2 variable, 6 Regressions), n-based calculations (dec, Hex, Oct, am, pen), etc. and logical operators.
