Casio has redesigned the ClassPad series' software keyboard to make this new model easier to use, organizing functions to correspond to three levels of learning difficulty, beginning with basic functions used by everyone like fractions, square roots, and trigonometric functions, then advanced functions like differential calculus, complex compound numbers, and sigma calculations, and finally even more advanced calculations including piecewise and user-defined formulas.
