Casio presents the new ClassWiz series with the technical-scientific calculators FX-991DE X and FX-87DE X. This series offers numerous innovations: an LC display that has four times the resolution of the familiar displays from the FX-DE Plus series. A spreadsheet function that allows users for the first time to utilize basic spreadsheet calculations on a technical-scientific calculator. And result visualization on a smartphone or tablet, made possible through the newly available QR codes.
