title: Multiply two input field and result in the third field which changes when either of the input field changed with jQuery
body: <p>I need to Multiply two user Input Fields and show the results in the third field. The Result field must change when either of the User Input fields are changed.</p>
  
  <pre><code>&lt;input type="number" name="rate" id="rate" /&gt;
  &lt;input type="number" name="box" id="box" /&gt;
  </code></pre>
  
  <p>The result should be in a third field which changes when either of the two above fields is changed. This totally depends on the user input</p>
  
  <pre><code>&lt;input type="number" name="amount" id="amount" readonly /&gt;
  </code></pre>
  
  <p>I need to do this Multiplication with Jquery.</p>
  
  <p>Thanks in advance</p>
