I got stuck on this tiny problem: I just can't understand how can I get the values from every input form and concat it. For example, if in one form I will write "Hello" and in another "World", it should return "Hello World" in the div with .results class. Thanks in advance!

```
<!DOCTYPE html>
<html>
    <head>
      <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
      <style>
      </style>
    </head>

    <body>
    <input type=text value=""/>
    <input type=text value=""/>
    <input type=text value=""/>
    <input type=text value=""/>
    <div class="results"></div>
    </body>

    <script>
    $(document).ready(function() {
              $('input').keyup(function() {
              $('.results').html('<b>' + $(this).val() + '</b>');
              });
          });
    </script>
</html>

```
