Detailed explanation-1: -In 1821 Babbage invented the Difference Engine to compile mathematical tables. On completing it in 1832, he conceived the idea of a better machine that could perform not just one mathematical task but any kind of calculation.
Detailed explanation-2: -What was the Difference Engine? It was an automatic calculating machine designed by Charles Babbage (1791– 1871), English mathematician and polymath. He conceived the machine in 1821, in response to a dismaying number of errors in mathematical tables calculated by hand.
Detailed explanation-3: -He left Cambridge, obsessed with the idea of using machines to speed up time-consuming mathematical calculations. Thus the idea of a Difference Engine was born. Charles also envisioned a machine that would handle more decimal places to speed the process of “carrying” and “borrowing."
