A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was created by Charles Babbage.

Difference Engine, an early calculating machine, verging on being the first computer, designed and partially built during the 1820s and ’30s by Charles Babbage.

Difference engines are so called because of the mathematical principle on which they are based, namely, the method of finite differences. In general, calculating the value of a polynomial can …

In 1822 he received funding for the device, called the 'Difference Engine', and hired a toolmaker, Joseph Clement, to build it. The Difference Engine called for nearly 25,000 parts in total, one …

The Difference Engine uses the mathematical principle that the differences between consecutive values of a polynomial eventually become constant. For a quadratic equation (degree 2), the …
