Notes:	The CASIO fx-82 series started with the CASIO fx-82, an ordinary scientific calculator. But CASIO kept extending this line, turning it not into just a model number but a whole calculator series. Trying to make it the non-programmable scientific calculator for school use. So far I’ve found mention of the following types: CASIO fx-82 (this one) CASIO fx-82A CASIO fx-82B CASIO fx-82C CASIO fx-82D FRACTION CASIO fx-82L FRACTION CASIO fx-82LB FRACTION CASIO fx-82LP CASIO fx-82SX FRACTION CASIO fx-82 NASER CASIO fx-82SUPER FRACTION CASIO fx-82SOLAR FRACTION CASIO fx-82TL CASIO fx-82MS CASIO fx-82MS-2 CASIO fx-82W CASIO fx-82ES CASIO fx-82ES PLUS CASIO fx-82EX CASIO fx-82NL CASIO fx-82ES PLUS CASIO fx-82CE X CASIO fx-82CW CASIO fx-82MS 2 CASIO fx-82 SOLAR II Improved version of the yellow-display predecessor CASIO fx-80 and its sibling, the cheaper CASIO fx-81. This calculator (as do many other CASIO scientific calculators) uses one and the same key for both the constant π as well as exponents. This works as follows. When you first enter digits, the EXP key will enable you to enter the exponent, otherwise it will enter the constant π. It is a robust and solid calculator for school usage. The fact that it uses ordinary (AA) batteries is also a big advantage.
