So why aren't you learning soroban maths /sci/?

>faster than a calculator
>stimulates both sides of brain
>increases powers of visualization in the mind after you ditch the physical soroban and just go straight MENTAL

I have an autistic little "math shrine" in my kitchen, and one of the pieces is a soroban. I would like to git gud but I just haven't gotten around to it. Also the thing is delicate so I'm concerned about breaking it.

Other items on the autistic math shrine: a slide rule (which I also don't know how to use), a Connect Four board laid out in a particular draw state, A Go board with the spiral pattern from the movie π, and a classic and 2^3 mini-rubik's cube, both unscrambled.

I had a soroban when I was a kid.
The "instructions" were in English by someone who thought in Japanese and I never did figure it out.
I CAN use an abacus (2 beads above the crossbar) and used all the scales on my slide rule (not just C and CI) with ease.

The "faster than a calculator" stories are left-overs from the post-WW2 occupation when a skilled soroban operator beat some GI using one of the old electromechanical (or maybe even hand-cranked) calculators. Those were marvels of mechanical ingenuity that made crunching and clanking noises as the carriage went back-and-forth like the platen of a typewriter. (You DO remember typewriters?)

>>	Anonymous Sun Mar 18 13:15:54 2018 No.9601002 Because it takes ages to get good at and it's not clear I'll be able to apply it to actual computations like infinite series easily
