If anyone has any idea how to go through this, with any good books, samples will be rewarded. I went through w3 school all the task, read some books, but it is not enough for understand loops.
Hexadecimal is a number system just like our decimal base 10 system. To say it's "pure math" is like saying the decimal system is pure math. It's just a way to represent numbers.

A good book would be a book reference for Hexadecimal and PHP, not a math book.
