In Section 9.1, we defined a finite set to be the empty set or a set \(A\) such that \(A \thickapprox \mathbb{N}_k\) for some natural number \(k\). We also defined an infinite set to be a set that is not finite, but the question now is, “How do we know if a set is infinite?” One way … The most primitive method of representing a natural number is to put down a mark for each object. Later, a set of objects could be tested for equality, excess or shortage—by striking out a mark and removing an object from the set. The first major advance in abstraction was the use of numerals to represent numbers. This allowed systems to be developed for recording large numbers. …
