From studying the theory of metric spaces, we generalize the everyday concepts of length and distance. As a good inroduction to the subject, it is shown that the Euclidean norm is a metric. This is a one-page study on the most well-known and practiced metric. It is ideal for the student beginning or who wants to begin with formal mathematics training. Provided below is the table of contents.
