Peer Note: Just a heads-up—genuine Casio fx-991ES models usually feature over 400 functions and a dot-matrix display. This specific packaging is a bit of a hybrid, as it lists the "240 Functions" and "2 Line Display" typical of the lower-tier fx-82MS or fx-350MS models. It’s a great budget-friendly option, but may lack some advanced matrix or integration features found in the standard fx-991ES "Plus" versions.
