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:

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 numbers 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.
