jQuery multiply and addition not adding total value
<p>Please take a look at the following URL: <a href="http://jsfiddle.net/XBtgD/2/" rel="nofollow">http://jsfiddle.net/XBtgD/2/</a>.</p>

<p>The additions are working fine, however the multiplication part doesn't add up at all.</p>

<p>Any ideas on how to get the multiplication working along with the additions?</p>

<p>Any help would be greatly appreciated.</p>
