Etymology

The word subtraction originates from Latin subtractio, derived from subtrahere ("to pull from under"). The morpheme sub- means "under" or "away," while tract comes from trahere ("to pull"). Combined, they convey the idea of "taking away" or "removing," which aligns with its mathematical and general usage. The suffix -ion turns the verb into a noun, solidifying its meaning as the act or process of subtraction.
