I was thinking this will boost my speed in multiplying but it has no diffrence from writing on paper

I also start learning soroban, from my view this is 1st step for beginning. In the higher level, they no longer use abacus . instead, they will calculate with imaginary abacus. This is the golden key to practice mental arithmetic and activate the right hemisphere of the brain
