Nice review. The QR code reader is quite useful for visualisations. Also, don't forget that the 991-EX also has spreadsheet mode, ratio mode, distribution mode and duel Table mode on top of what the 991ES has.
perfectly explained! this grey casio would make my life a lot easier because i have problems in maths at school. with this calculator i could watch your videos and learn even more with it! :D
Nice vid. Just bought the EX on the Bay of e for £17.50 which seemed pretty good value. Also, do you have the details of the main backing track you used for this vid?
It's simply to compare raw processing power. I like using sum from 1 to 500 of -x^2 since on the ex it takes 12 seconds but most calcs like the es series and ti 36 take around 2 minutes
Depends on your choice of you want sturdy long-lasting one es is best but the ex model is also very nice looking and has lot of features like qr code pick one and message your choice
