Pascaline (1642)

Set of gears, similar to clock Only performed addition and subtraction

Abacus

Tally stick was replaced by it. a mechanical device used to aid an individual in performing mathematical calculations. Was invented in Babylonia in 2400 B.C. In the form we are most familiar with was first used in China in around 500 B.C. It used to perform basic arithmetic operations.

Z1

The first programmable computer. •Created by Konrad Zuse Germany from 1936 to 1938. •To program IT required that the user insert punch tape into a punch tape reader and all output was also generated through punch tape.
