The number system we commonly used, known as the decimal system, has 10 digits (0 to 9). It is possible to use other number systems, with a different number of digits. Any numbering system based on the same principle (the principle of place-value) must use 2 or more digits.

It is only true in the sense that any numeric base, expressed in that base, is represented with the symbol "10". Confusing? Let's clarify that. Hexadecimal numbers use sixteen as the base. But how do you express the value sixteen in hexadecimal? Quite easy, it would be written as "10". The same is true in any other base. For example, in binary (base two), the value two is expressed as "10". In octal (base eight), the value eight is expressed as "10". In decimal (our familiar base ten), the value ten is expressed as "10". No matter what base you work in, the base itself will always be expressed as "10". That however is not the same thing as saying that hexadecimal numbers are based on the number ten. That is incorrect. Hexadecimal numbers use the base sixteen.

working with bases means to change the numbering system that you currently use. For base six, it goes 1,2,3,4,5,10,11,12,13,14,15,20. Looking at the sequence we see that "20" in this case is 12 of base ten..the numbering system we use. So "15" is 11, "24" is 16, and "31" is 19. You can work it from there.

Base 16 numbering is called 'Hex' or 'Hexadecimal'. Base 8 numbering is called 'Octal'. Base 2 numbering is called 'Binary'.

Computers do much of their processing in binary. Hexadecimal is used as a kind of shortcut (easier to read for humans): each hexadecimal digit represents four binary digits.
