But an operation does not exist in vaccum.  An operation needs data in
order to have meaning.  Both two are characterized by the relations
tieing them.  

Now, we need to get down from the Abstration Tower and consider
sennsible things we're operating on.  The question is to give sensible
meanings to the behaviour. And designing datatypes for those tasks is
the right choice here.
