The XOR and AND gates represent the sum and carry of the numbers A and B added together
0 +0 = 0
1 + 0 or 0 + 1 = 1, with no carry.
1+ 1 = 2, but 2 is not a binary number. In binary, 2 is represented as 10. The 1 is the
carry and the 0 is the sum.

The truth table represents the sum and carry of the numbers A, B, and Cin added
0 +0 +0 = 0
0 + 0 +1 = 1, with no carry.
0+1+1= 2, but 2 is not a binary number. In binary, 2 is represented as 10. The 1 is the
carry and the 0 is the sum.
1 +1+1 = 3. In binary, 3 is represented as 11. The first 1 is the carry and the second 1
is the sum.
