=== Counting in binary ===

We are used to digits from 0 to 9. But did you ever think how we actually count?

When we start with 0 and keep adding 1 we get the following sequence:

  0
  1
  2
  3
  ...
  8
  9

After this happens we run out of digits. So we reset the current digit and add 1 to the next one

  9
  10
  11
  ...

This works the same in binary, however there are only two digits available: 0 and 1.

So if we want to count, we count:

  0
  1

And we're already out of digits, so we reset the current digit and add 1 to the next one:

  0
  1
  10
  11
  100
  101
  110
  111
  ...

You may have heard about Hex or "Hexadecimal", which is the same principe as this, but it uses 16 different digits. 0-9, and after that, A-F.
