It is therefore possible to implement a half-adder with just these two logic gates:

At this point we have completed the addition and have successfully added the three bits: $1$, $0$, and $0$ to get $1$ as ths sum. However we also have to account for the fact that the addition may result in its own carry-out bit. What if the inputs were $1, 1, 0$ for example?
