The slide rule very much simplified calculations of multiplication and division, especially were a ratio was to be used over and over. Edmund Gunter had already invented the Gunter scale, but it was clumsy and required dividers (the things like compasses, but with two sharp ends instead of one sharp end and a piece of pencil lead) to use. William Oughtred realized that two Gunter scales facing each other made it unnecessary to use the dividers. That realization was the invention of the slide rule.
The slide rule was developed to perform multiplication and division before calculators had been invented. a addition and subtraction
