HTML entities were described in the previous chapter.
Many mathematical, technical, and currency symbols, are not present on a normal keyboard.
To add such symbols to an HTML page, you can use an HTML entity name.
If no entity name exists, you can use an entity number, a decimal, or hexadecimal reference.
These are like number replacements for the code, and work just as well.
I got some information from <p>http://www.w3schools.com/html/html_entities.asp<p>
