Jul 06, 2018

The calculator is the earliest computing tool. For example, Quipu or khipu is a method of knotting notes by the ancient Incas to count or record history. It is made up of rope knots in many colors.

There are also ancient Greeks of Antikythera, Chinese abacus and so on. The first calculation tool used in ancient China was called planning, and it was also called calculation. This kind of calculation is made of bamboo, and it is also made of wood. The animal bone acts as a material. A bundle of about 270 pieces can be carried in a bag. The abacus that is still in use today is another invention in the field of computational tools in ancient China. The abacus in the Ming Dynasty was almost identical to the modern abacus.
