If you think of the decimal system using columns:
1000
(10x10x10)
The number 1019 is:
1000
1
Each time you add 1 to a column that contains 9, that column
goes back to 0 and you add 1 to the column to the left. The
columns represent powers of 10: 10x10, 10x10x10 and so on,
and the decimal system is said to be base 10.
The hex numbering system uses a base of 16. Hex numbering
works in exactly the same way as the decimal system, except
you must add 1 to a column that contains 15 before you add
1 to the column to the left.
As we have no single character to represent the numbers 10
to 15, we substitute the first six letters of the alphabet, so
that:
The example number 1019 can then be represented in hex
by:
4096
(16x16x16)
