In 1821 Babbage invented an Engine to manufacture error-free mathematical tables, Difference Engine No.1, the world's first programmable automatic digital calculating machine, in which the only human intervention was the setting of the machine at the start of the production of a table and the turning of its handle. It was a machine embodying the mathematical principles of the Method of Differences using only mechanisms for addition repeated many times over.
