The word "abacus" was first mentioned by Xu Yue(160–220) in his book suanshu jiyi (算数记遗), or Notes on Traditions of Arithmetic Methods, in Han Dynasty. As it described, the original abacus had five beads (suan zhu) bunched by a stick in each column, separated by a transverse rod, and arrayed in a wooden rectangle box. One in the upper part represents five and each of four in the lower part represents one. People move the beads to do the calculation.
