Casio - fx-82

Description

Brand: Casio
Model: fx-82
Type: Scientific calculator
Batteries: AA x 2
Lifetime: Introduced: unknown
Terminated: unknown
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:



This one, together with the Casio fx-81, was the most popular calculator when I was in high school. These calculators were basically the same. The only difference was that the fx-81 wasn't officially capable of doing statistical calculations. To enter the statistical mode one had to press "INV" "DoRoG" on the Casio fx-82. When these keys are pressed on the Casio fx-81 the display shows "error" at the position where the Casio fx-82 shows "sd". However, all statistical functions are there, it's just a matter of remembering the Casio fx-82's key layout!

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.
