When the number place holder is empty, it has a zero in it. When
full, there is a 1.
Look
at the first example, the number one.
When
we add a 1 to the number 1, the first place holder becomes a zero
and we carry one place to the left. The zero (the second from
the left) now becomes a 1. So a number 10 in the binary system
equals a number 2 in the base 10 system. |
