The benefit of learning something like the abacus is in teaching your mind to more efficiently structure numbers for calculation... see the other youtube videos for speed-math abacus competitors in Japan... they don't even use the physical abacus, it's all imaginary and mental. If I practiced using a calculator hours on end, I'd get pretty damned fast at it, myself!
