 however, must satisfy some additional properties. Let's examine the properties
 in the context of `min` and `max` as we have before. They are usually called 
 the _absorption laws_:

 * `max(a, min(a, b)) = a`. `a` is either less than or bigger than `b`;
   so if you try to find the maximum __and__ the minimum of `a` and
