The short answer is that the scales are log scales ( at least the C and
D scales ). So when you add the length of part of one scale to the
other scale, you are essentially adding logs and therefore multiplying.
Or if you subtract the length of one from the other, you are
subtracting logs and dividing.

how
to use a slide rule got me nowhere. Is there anything out there that

describes how to actually use one?
