title: Add / Divide Numbers in PHP
body: <p>I am working on a Facebook App that needs to be able to average three numbers. But, it always return 0 as the answer. Here is my code:</p>
  
  <pre><code>$y = 100;
  $n = 250;
  $m = 300;
  $number = ($y + $n + $m / 3);
  echo 'Index: '.$number;
  </code></pre>
  
  <p>It always displays Index: 0</p>
  
  <p>Any ideas?</p>
