CHAPTER 2 The Language of Sets Before going farther with numbers, you should be familiar with sets and the symbols that describe their behavior.
But wait! What about the set of all abstract ideas? That’s an abstract idea. So a set can be a member of itself. ” In a way, it’s just a riddle. Nevertheless, riddles of this sort sometimes open the door to important mathematical discoveries. Here’s a challenge! Define the set of all the positive and negative whole numbers in the form of an “implied list” of numerals. Make up the list so that, if someone picks a positive or negative number, no matter how big or small it might be, you can easily tell whether or not it is in the set by looking at the list.
No doubt, this number is huge—larger than any calculator can 44 Natural Numbers and Integers display—but it will be finite. Let’s call it y. What if we add 1 to y, getting a number even larger than the product of all the primes? If you call that new number z, you can express it like this: z=y+1 = (2 × 3 × 5 × 7 × 11 × 13 × ... × p) + 1 Now we know that z has to be larger than p, because z is 1 more than, say, 2 × p or 3 × p or 5 × p or 7 × p. But there’s something else interesting about z. If we divide z by any prime number, we always get a remainder of 1.
