calculate a number without a variable in javascript
<p>Given this code: </p>

<pre><code>if(ipadmenuheight &lt; contentheight).css('top', '' + contentheight + 44 + 'px');
</code></pre>

<p>Let's say <code>contentheight=500</code></p>

<p>then this code snippet returns <code>50044px</code>. How can it be a sum instead and return  <code>544px</code>?</p>

<p>Do I need to use a variable or can I do this inline?</p>
