Examples of a numeration system are:
Base 10 or decimal. This system (which is the system that everyone is familiar with) has ten digits 0, 1, 2, 3, 4, 5 6 7 8 and 9. The least significant column has a weighting of 1, the next column to the left a has a weighting of 10 and each successive column to the left has a weighting 10 times that on the column on it's right.
Base 2 or binary. This system has only 2 digits 0 and 1. The least significant column has a weighting of1, the next column to the left has a weighting of 2 and each successive column to the left has a weighting 2 times that on the column on it's right.
EXAMPLES 1 10 11 100 101 110 111 are the equivalent of the decimal numbers 1 2 3 4 5 6 7.
Base 8 or octal. This system has 8 digits 0 1 2 3 4 5 6 and 7. The least significant column has a weighting of1, the next column to the left has a weighting of 8 and each successive column to the left has a weighting 8 times that on the column on it's right.
EXAMPLES 5 6 7 10 11 12 13 14 are the equivalent of the decimal numbers 5 6 7 8 9 10 11 12 or in binary 101 110 111 001000 001001 001010 001011 001100. 3 binary digits are used to represent each octal digit so octal 12 001 for the 1 and 010 for the 2 shown as 001010. It is normal to group the binary digits into 3's like this 001 010
Base 16 or hexadecimal. This system has 16 digits 0 1 2 3 4 5 6 7 8 9 A B C D E and F. The least significant column has a weighting of1, the next column to the left has a weighting of 8 and each successive column to the left has a weighting 8 times that on the column on it's right.
EXAMPLES 8 9 A B C D E F 10 11 12 are equivelant to the decimal numbers 8 9 10 11 12 13 14 15 16 17 18 or to the binary numbers 1000 1001 1010 1011 1100 1101 1110 1111 00010000 00010001 00010010
note that 15 decimal = F hexadecimal = 1111 binary. Each hexadecimal digit is represented by four binary digits; so 12 hexadecimal has four binary digits to represent the 1 and another four digits to represent the 2 i.e. 0001 and 0010. Shown as 00010010.
It is normal to group the binary digits in this case into 4's like this 0001 0010

In the international system of numeration, a number is split into periods or groups and classified accordingly for example ones, tens, hundreds, thousands, millions and so on. It is followed by almost all the countries all over the world.
