Many mathematical currencies and technical symbols, like the **copyright symbol**, are not available on a keyboard. Therefore, to add symbols to an HTML webpage, an entity name, decimal, or hexadecimal reference can be used.
There are three methods to use for the copyright symbol in HTML:

| Method    |  Copyright symbol   |
| --- | --- |
| entity name    | `&copy`    |
| decimal reference    |  `&#169`   |
|  Hexadecimal reference   | `&xA9`    |

# Example code
All the methods mentioned above are given below:

<html>
 <head>
 </head>
 <body>
 Copyright symbol using entity name &copy;
 Copyright symbol using decimal reference &#169;
 Copyright symbol using hexadecimal reference &#xA9;
 </body>
</html>
