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.
