title: Division ("/") in function
body: <p>I'm trying to write a simple function of the division, but I get an error</p>
  
  <pre><code>PS C:\Users\john&gt; Function Div($x, $y) { $x / $y }
  PS C:\Users\john&gt; Div (1, 1)
  Method invocation failed because [System.Object[]] doesn't contain a method named 'op_Division'.
  At line:1 char:28
  + Function Div($x, $y) { $x / &lt;&lt;&lt;&lt;  $y }
      + CategoryInfo          : InvalidOperation: (op_Division:String) [], RuntimeException
      + FullyQualifiedErrorId : MethodNotFound
  </code></pre>
  
  <p>What is my mistake? Thanks</p>
