title: R o R (Discrete Mathematics - Relations on Sets)
body: <p>The following is given</p>
  
  <pre><code>Let A = {1, 2, 3, 4}
  
  Let R = the relation on the set A, or: 
  R = {(1,1), (1,2), (1,3), (2,1), (3,2), (3,3), (4,4)}
  
  Find R o R as a set of tuples.
  </code></pre>
  
  <p>I am not certain how to approach this problem.
  My best guess is</p>
  
  <pre><code>R o R = {((1,1),(1,1)), ((1,1),(1,2), ..., ((4,4),(4,4))}
  </code></pre>
  
  <p>but that does not seem right to me. I'm looking for how to solve this type of problem, not just a solution to this problem.</p>
  
  <p>Any help would be appreciated!</p>
