Graduates the scales logarithmically so that sliding one against another adds lengths and multiplies numbers.

Carries no decimal point anywhere on the instrument: the user tracks the order of magnitude mentally, which is why slide rule work required an estimate before the calculation rather than after it.
Contexts: Mathematics, Technical drawing
Graduation lines along parallel scales, crowded together toward the right of each decade and labelled with lettered scales for squares, cubes, sines and logarithms.
