This formalizes the operation of counting the elements of S. Also, n ≤ m if and only if n is a subset of m. In other words, the set inclusion defines the usual total order on the natural numbers. This order is a well-order. It follows from the definition that each natural number is equal to the set of all natural numbers less than it.
