What is the difference between the operator and the function? If a relation is a parallel between output and input, and a function is a relation of a single output to an input set, then what is an operation? The online concensus is that it's a function, but from there the definition gets fuzzy.

It is mainly a matter of usage. Functions are usually used from number(s) to number, while operators are usually vector to vector.

Would it surprise you if I said I have no idea what that means?
