Morphology
subtraction = subtract (transparent) = sub + tract + ion
Formed by clear nominalization of the verb 'subtract' with the productive suffix '-ion' to mean 'the act or process of subtracting'.
Etymology
The word subtraction comes from the parts sub- 'under' and tract 'pull', the same part you see in tractor, a machine that pulls. So subtraction means 'taking away' or 'pulling away', which is why it refers to taking one number away from another.
