The abacus is at once one of the oldest, most enduring, and efficient products of the human mind. It appeared early before arabic numbers, so it doesn’t have a sense of numbers. abacus does the calculation according to the different beads and the position of them to represent different numbers. The upper bead represents 5 and each bead below the horizontal beam represents 1. And the beads are considered to be calculated when they move close to the horizontal beam. | The abacus is at once one of the oldest, most enduring, and efficient products of the human mind.

Compared to nowadays calculation technology operated by simple click by button, abacus enlarges the process of calculation in an analog way. We can draw the graph below when take the position between the beads and horizontal beam as Y axis, the number it presents as X axis. As a calculation process which needs to be well trained and once defined abacus as a efficient tool, nowadays literally causes hardly use of abacus. | Compared to nowadays calculation technology operated by simple click by button, abacus enlarges the process of calculation in an analog way.
