title: Determine whether number is a multiple of 5
body: <p>How would I go about determining if a number is a multiple of 5?</p>
  
  <p>In my app, I want one method to run if a certain number is not a multiple of 5, and another method to run if the method <em>is</em> a multiple of 5.</p>
  
  <p>Thanks for your help!</p>
