what is the difference between jquery-1 8 2 js and jquery-1 8 2 min js

Question

i find a topic about difference between jquery-1.8.2.js and jquery-1.8.2.min.js that is

 1. jquery-1.8.2.min.js for  (compressed, for production) 
 2. jquery-1.8.2.js for (uncompressed, for debugging)

but I used jquery-1.8.2.min.js for my application, and I am getting an error: $ is not a function

If I use both jquery-1.8.2.min.js and jquery-1.8.2.js my application is working. Why?

I downloaded .js from http://blog.jquery.com/

Here is the HTML that includes the script on my page:

<script language="javascript" type="text/javascript" src="../../jquery.ui/jquery-1.8.2.min.js" ></script>
<script language="javascript" type="text/javascript" src="../../jquery.ui/jquery-1.8.2.js" ></script>

<script language="javascript" type="text/javascript" src="../../jquery.ui/jquery.ui.autocomplete.js" ></script>
