The OG Computer
Abacuses are one of the oldest analog computing technologies on Earth. For millennia, abacuses were used by merchants and bankers across the globe to help them visualize and calculate large numbers.
And the humble abacus may have one benefit that modern electronic calculators do not have. Advocates believe that calculating with an abacus can help you improve your mental math and memory skills. For this reason, soroban use continues to be taught in schools in Japan.
