Starting at the Beginning: The Natural Numbers,e will have to begin at the very basics—indeed, we will go back to the concept of . and what their properties are. Of course, you have dealt with numbers for over ten years and you know how to manipulate the rules of algebra to simplify any expression involving numbers, but we will now turn to a mor

Set Theory,f number system, the natural numbers. We will introduce the other number systems shortly, but for now we pause to introduce the concepts and notation of set theory, as they will be used increasingly heavily in later chapters. (We will not pursue a rigorous description of Euclidean geometry in this t

Limits of Sequences,al numbers. However, unlike our work in constructing the integers (where we eventually replaced formal differences with actual differences) and rationals (where we eventually replaced formal quotients with actual quotients), we did not completely finish the job of constructing the real numbers, beca
