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.
