Description

There are 2 versions of this calculator: the fx-7400G PLUS made in 1999 and the fx-7400G PLUS-GY made in 2004.
Funcional the calculators are the same, but the outside has been fully redisgned. The 4 function keys, the G<->T key and the right arrow now have oval shapes. The fx-7400 doesn't have the functions of its bigger siblings like the 9750, 9850 and so on but it does have one unique feature: battery life: 1500 hours on a single pair of batteries, pretty decent for a graphic calculator. And it only requires 2 instead of the usual 4 batteries.

To do anything useful, you'll need Casio software. Should probably be available at the Casio website.

There are 2 versions of this calculator, the above shown is the fx-7400G PLUS made in 1999, the other is the fx-7400G PLUS-GY made in 2004, same functions but fully redisgned outside (F's, g-t and right arrow has oval shape, same directional key shape and mouth-oval shaped the rest of keys), doesn't have the functions of bigger models like 9750, 9850 and so on but win in unique features: one is authonomy, 1500 hours is a decent amount for a graphic calculator, 2 batteries instead of 4, simplification of fractions, integer division, pie charts, etc. Got a GY and I'm proud of it
