Digital becomes a way of life nowadays… People might not understand how it works, but we are using it everyday, from watches to appliances, from rockets to cars, from cameras to calculators…
The first digital system was invented by Chinese around 3000 B.C. It’s the abacus. It has been used until recently in most of the Asian countries like China and Japan.
My father used to be an accountant and he could use this abacus professionally even faster than a normal calculator.
Well, in this digital era, this little system becomes more like a culture or an art rather than a scientific instrument.
Don’t you agree with me?
