Unboxing and Using the Casio fx-991 EX for the First Time
I ordered and now just received a Casio fx-991 EX Classwiz calculator. The fx-991 EX is the first calculator to produce QR codes, which can be processed through the CASIO EDU+ app (iOS and Android). It is the closest we have to a solar-panel graphing calculator (by use the Tables and Stats modes and QR codes), something I always dreamed of having. This is a pretty spontaneous video. I am going to have a more detailed review of the fx-991 EX on my blog: edspi31415.blogspot.com. Hopefully the lighting isn't too bad.
