Notes: This is one of the few calculators I bought new. It was quite expensive too. This is one of the first pocket calculators with a big LCD and it often needed new batteries... A bit too often in my opinion. It would have been better if this calculator had been designed for plain AAA batteries.

According to Casio's own page with chronological data world.casio.com/corporate/history/chronology (link valid 2022-01-03) this calculator is the worlds ever first graphical calculator.

This is the bigger brother of the Casio fx-6000G.

The Casio fx-7000G has all the functions that can be found on other Casio calculators and adds some graphing capabilities. The programming "language" was similar to that of the Casio fx-4000P. If can also perform calculations in other number systems, and does binary operations.

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.

The calculator has rubber keycaps which take some getting used to but work really great and result in fewer mistakes when you get used to it.
