title: Simple math in jquery
body: <p>I am reading a select form value and multiplying it by 50 in jquery. I need to add a value of 1 to the qty that is returned by the select menu every time before multiplying by 50. How would I do that? The offending code looks like this.</p>
  
  <pre><code> $('#selectform').val() *50);
  </code></pre>
  
  <p>If I use </p>
  
  <pre><code> $('#selectform').val() +1 *50);
  </code></pre>
  
  <p>The result is not correct. </p>
