### Example of addition of two unsigned binary numbers

Binary addition is done like adding decimal numbers, except that you
have only two digits. You have to remember only that:

0+0 = 0, with no carry,

1+0 = 1, with no carry,

0+1 = 1, with no carry,

1+1 = 0, and you carry a 1.

Let's add the following unsigned binary numbers: 11111 and 10101.
