Casio’s fx-CG20 calculators go graphical

In a ground breaking move, Casio is set to turn the world of calculators on its head yet again with the launch of its fx- CG20 graphing calculator. Casio created the world’s very first graphing calculator back in 1985 with the 422 byte fx-7000G, giving maths students the opportunity to create their own graphs by inputting complex equations directly into the calculator and viewing the results of their labours on a small mono screen. It was cutting edge at the time, but its heavily tokenised programming language allowed it to perform some pretty chunky tasks nonetheless.

Casio’s new calculator has two revolutionary features to it. A 3.7 inch high resolution display capable of 65,000 colours, making those pie charts almost too sexy for words; and perhaps more importantly, a picture plotting application, another world first for Casio. It opens up a whole new way to learn maths by enabling students to experiment with creating their own graphs over pictures of real life scenes. For example, there are already fifty five built in pictures that can be accessed such as the parabola of jets from a water fountain or an image sequence of a clock’s pendulum movement.

Of course, with such a generous colour palette, spreadsheets can be brought to life and colours can be added to standard graphing objects such as dotted lines, circles and bars etc. They can be linked to values in the spreadsheet screen and the calculator will automatically colour-code brackets when there are equations using multiple brackets.
For scale demonstrations the calculator can be connected to one of Casio’s green Slim Line projectors for super size imaging.

Clearly, this new technology will find its way into mainstream calculators and will no doubt ensure that Casio remains at the forefront of a market it has dominated for decades.

The fx-CG20 will retail at £129.99
