Its not calculator dependency, is that at least in america, they don't teach problem solving skills, actively discourage using them and instead focus on memorization and 'this is the way we do it and it works, your way also works but your wrong' at least for me my math skills come from min maxing and rpgs, my reading from gaming books, most of what I use on a daily basis was all self taught far earlier than schools taught it, if they thought it at all. if my math teachers could see the math needed to reverse engineer the ac calculations in everquest, and then see how close I was to how its actually calculated, I think nearly all of them except 1's head would explode.

considering how white his hair is, makes me wonder how he cares that smooth skin, or is it photoshopped?

@imadoathing ohh i see now, that's why the divide by 10 wouldn't work because we're talking about different sheets, amazing!.

@Cryotic thanks anyway, it's too hard to wraparound for someone so accounting-challenged like me, love your avatar btw :D

Holy sheet didn't expect to learn something useful in this manga. That divide by 9 is pretty useful

And with that the villainess ensnared the prince with her mysterious and sensual accounting techniques.

It's kinda ludicrous that they don't know what an abacus is. A device independently invented across the world. I mean, it originated in mesopotamia, but even the america's had it. Just seems like bad writing.
