Morphology

operation = operate (semi-transparent) = operate + ion

The mathematical/computing sense ('a specific action or calculation') is a technical extension of 'to perform an operation', so it is predictable but domain-specific.

Etymology

Operation comes from Latin operari, meaning 'to work', and in math it means an 'action' you do to numbers, like addition or multiplication. This is why we call adding or dividing a mathematical operation.
