We will use the intuitive notion that the line has no gaps and that every conceivable distance can be represented by a point on the line. With these concepts in mind, we call the line shown above the real line. We think of each point on the real line as corresponding to a real number. The undefined intuitive notions (such as “no gaps”) can be made precise using more advanced mathematics. In this book, we let our intuitive notions of the real line serve to define the system of real numbers.
