Scientific calculator with 240 functions Description

The 240-function scientific calculator is specially designed for middle school students (grades 6-9), vocational students (BEP, CAP), and for university, office, and post-school use! * 2-line display showing operations. 4 navigation arrows for correcting or modifying calculations. * Calculation and display of proper and improper fractions. Percentage calculations. * Scientific functions: p, trigonometric (cos, sin, tan), hyperbolic (cosh, sinh, and tanh), logarithmic (log, ln, e^x) and their inverses. * Square, square root, cube root, cube root, and xth root functions. * Factorial calculation (n!), random number generation, permutation, and combination. * Calculations in base 2, 8, and 16 with logical operations (AND, OR, XOR, XNOR, NOT). * Single-variable statistics: calculation of total frequency (n), mean (x), standard deviations (sn-1, sn), sums (Sx², Sx). * Conversions: between degrees/radians/grads and rectangular/polar coordinates. * Ultra-comfortable and robust
