The first calculating devices

Слайд 10

The first calculating devices Then people invented the abacus, a bead frame in which the beads are moved from left to right. People went on using some form of abacus well in the 16 th century. In fact, the oldest abacus was used in 300 B.C. by the Babylonians. The abacus is still in use today, principally in the far east.

Leonardo da Vinci In XV century Leonardo da Vinci invented the summing device with gear wheels carrying out addition of 13-digit numbers.

Слайд 12

In XVI century the German professor Wilhelm Schickard invented summing « calculating clock » . It carried out addition and multiplication of 6-digit numbers. Wilhelm Schickard

Слайд 13

The first mechanical adding device was developed in 1642 by the French scientist-philosopher, Pascal. His machine « Pascalina » carried out addition and subtraction of 8-digit numbers. Blaise Pascal

Слайд 14

In 1671 Leibniz, a German mathematician and philosopher invented the mechanical adding device which was capable of also doing multiplication, division and the evaluation of square roots by a series of stepped additions, not unlike the methods used in modern digital computers. V. G. Leibniz

Слайд 15

Charles Babbage, an Englishman invented the first calculating machine in 1830. It was called « the Analytical Engine » . It carried out automatic calculations : Warehouse (data storage) ; Office (management) ; Data input and program with punched cards. Charles Babbage
