The slide rule is a mechanical analog computer. The slide rule is used primarily for multiplication and division and for functions such as exponents, roots, logarithms, and trigonometry. They are not designed for addition or subtraction which was usually performed manually, with scientific notation used to keep track of the magnitude of results. Maximum accuracy for standard linear slide rules was about three decimal digits.
