Our society uses numerical system with base 10. Simple explanation why this system is used - simply because people have ten fingers, thus this is the easiest way for us to calculate numbers. If things were gone different, and something had messed up primordial soup -> developing Homo sapiens with eight fingers, it would be more likely we would use octal numeric system in present time. Infinite number of numerical systems exist, but following are most commonly used...

Decimal System:

Base: 10

Digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

Octal System:

Base: 8

Digits: 0, 1, 2, 3, 4, 5, 6, 7

Example: 27 (decimal) = 33_{8} (octal)

Hexadecimal (hex) System:

Base: 16

Digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F

Example: 27 (decimal) = 1B_{16} (hex)

Binary System:

Base: 2

Digits: 0, 1

Example: 27 (decimal) = 11011_{2} (binary)
