Abstract

You should be familiar with the method of representing numbers as points on a number line. A horizontal line, or axis, is drawn, with two special points marked 0 and 1; 0 is called the origin, and is to the left of 1. The positive number x is represented by a point on the axis whose distance to the right of 0 is x times as far as the distance from 0 to 1. We usually say the distance from 0 to 1 is the unit distance, and say the point representing x is x units to the right of the origin. Negative numbers go to the left of 0, and — x is x units to the left of the origin.
