To Add two integer you can use full adder at bit level.
if bit1 and bit2 are kth bits and car is previous carry then
sum = bit1 ^ bit2 ^ carry;
carry = bit1.carry + bit2.carry + bit1.bit2;
here ^ = bitwise zor
. = bitwise and
+ = bitwise or
repeat it for all bits of two integer, initially prev carry will be 0;
