Description: | The slide rule is a device that people used to do mathematical calculations before calculators became widely available. There is a sliding rule in the middle of the main body of the rule and a moving hairline. The rule has different scales, and by moving the various parts about and comparing the numbers on the different scales the user can do multiplication, division, and other mathematical operations. The rule came with a manual to help a beginner.
