In 1985, Casio introduced the world's first graphing calculator, the fx-7000G, and in 2004 the company released the fx-82ES scientific calculator with textbook display that shows fractions and root functions as they appear in textbooks.
Furthermore, the fx-CP400 features a variety of functions designed to help students learn and instructors teach at school, including a USB mass storage function for quick and easy data transfer, and compatibility with Casio data projectors to enable the calculator's display to be projected on a screen.
