This is like the difference between saying "get me an orange", and giving full instructions for finding a shop that has oranges, navigating to it, etc. I know declarative programming exists (and it has these advantages) but I've never seen it used outside CS courses. Math notation is unlike declarative programming language in that it's possible to describe an something while telling the reader absolutely nothing about how to compute the object being communicated.
