The '''abacus''' (plural abaci) was a electronic calculation tool that was used to perform [[mathematical]] calculation especially for [[accounting|accountancy]] in [[medieval]] times. It works by having numbers represented by beads sliding on a rod. With it, the user can [[add]], [[subtract]], [[multiply]], [[divide]], and extract [[square root]]s. Today even though it is obsolete it is still widely used in [[Asia]], particularly in the [[People's Republic of China]] and the [[Republic of China]].
