title: Performing math function in array for Swift
body: <p>I'm new to programming, and having a difficult time taking the array below and performing a mathematical expression on each index then printing the result.</p>
  
  <pre><code>var projectOne = [ 1, 3, 5, 0, 6]
  for addition in projectOne {
      print( projectOne "plus 4 is" \projectOne = projectOne + 4)
  }
  </code></pre>
