not a calculator because it only records the answer to the problem, it cannot give it
The abacus (plural abaci) was a digital calculator 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|square roots]]. Today even though it is obsolete it is still widely used in [[Asia]], particularly in the [[People's Republic of China]] and the [[Republic of China]].
