TitlePocket Slide RulerObject TypeObjectDate1940DescriptionPocket Slide Ruler.

Slide rules were used mostly for multiplication nd division, not for measuring lengths.

Each number to be multiplied or divided was represented by a length on a slide rule which had a logarithmic (non-linear) scale. The numbers were aligned on the slide ruler to read the sum of the logarithm and then calculate the two numbers.
