Slide Rule Operations and Functions

This video tutorial introduces the basic operations of a slide rule, a tool used for calculations before the advent of pocket calculators. It covers multiplication, division, squaring, and cubing, explaining how slide rules utilize logarithmic scales. The tutorial includes examples of multiplying and dividing numbers, as well as finding square and cube roots. The video concludes with a brief mention of trigonometric functions, which will be covered in a future video.
