The one half-adder can add the least significant bit of the two numbers. Full adders are required to add the remaining 15 bits as they all involve adding carries.

Please clarify me for this problem. As I have read a number of full adders required is = 2^n, where n = number of bit, then here 15 full adders. How? Please explain.
