In order to automate the mathematical calculations that were done by people previously, computers were introduced. Charles Babbage who is known as the father of computers saw a need to negate the human errors in computations and the requirement of an automated system that would help with those errors. Before people used to sit for hours to perform mathematical calculations by hand and record them in books and since these calculations were vitally important, there was no possibility of any errors. Therefore, in order to help with those calculations computers were introduced in the first place.
