title: Prime backwards in order
body: <p>An emirp (prime spelled backwards) is a pime number whose reversal is also prime. Ex. 17 &amp; 71. I have to write a program that displays the first 100 emirps. It has to display 10 numbers per line and align the numbers properly:</p>
  
  <pre><code>2   3    5      7     11     13      17     31      37      71
  73  79   97    101    107    113     131    149     151     157. 
  </code></pre>
  
  <p>I have no cue what I am doing and would love if anyone could dump this down for me.</p>
