Casio fx-82AU Plus II
Brief History
Several special calculator was developed on the base of fx-82MS, ES, EX series, mostly for the education in different nations. The french fx-92 series is in production since 1993, the australian fx-82AU version was announced in 2005, since then more variation introduced. The last of them is the fx-82AU Plus II (2013), which differs from the well-known fx-82ES models in simplifying fractions, calculating least common multiple (LCM) and greatest common divisor (GCD), and it has an unique Verify mode to check whether an entered equation or inequality is true or false.
