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: -A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions. It was designed in the 1820s, and was first created by Charles Babbage.
Detailed explanation-3: -In 1822, Charles Babbage conceptualized and began developing the Difference Engine, which is considered the first automatic computing machine that could approximate polynomials. The Difference Engine was capable of computing several sets of numbers and making hard copies of the results.
Detailed explanation-4: -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.
