Do all Gemstones not require calculations? I mean, Himegami's Deep Blood is entirely passive, and Gunha's ability is something even he doesn't understand, so it's reasonable to say there's no calculation involved in those two. We don't know enough about the Gemstone Girl's ability, and I'm not sure if "White Player" even exists in canon, so I'd put those as "maybe." And since they don't necessarily need to go through the power curriculum to develop their abilities in the first place, they may not need the mathematical skills that they'd learn in school to use them.
