Long before the advent of calculators, merchants of Chinese origin depended on this simple yet ingenious machine for doing their math on their day-to-day transactions and business P & L. The “click-clack-click-clack” sounds of the Abacus beads beating against one another was the music of money to their ears
Honestly, it was amazing to see how deftly the experts manipulated the beads up and down each column. I ever tried learning this art of “Finger-Flicking-Good” at an early age, but gave up after a short while. Well, maybe because I was not born to be a bean counter.
I think there are some shops, such as Chinese “medical halls” where these ancient calculating machines are still in use. But I do not think their use is going to outlast me on this planet.
