I have seen a number of calculators and observed that most of them will turn on only if you hit a dedicated on/off or c/ac button. They won’t turn on if you just hit any random button, which really sucks because when I hit “9”, I want to see “9” on the display and continue my calculation. But this isn’t happening.
If I were an accountant, I would complain. But since I am not an accountant, I am only curious.
Calculators should be made to react on any button. Since most calculators are powered by solar anyway, accidental turn-ons won’t even harm the battery. It’s just a little something that has to be done to keep up with user expectations.
Casio, please take a note. Screw “on” and “off” buttons.
