Exercise 2: Adder-subtractor:• Two binary numbers can be subtracted by taking the 2's complement of the subtrahend and adding it to theminuend.• The 2's complement can be obtained by taking the 1's complement and adding 1.• To perform A - B, we complement the four bits of B, add them to the 4 bits of A, and add 1 through theinput carry.• This is done as shown below. The 4 XOR gates complement the bits of B when the mode select M = 1 andleave the bits of B unchanged when M = 0. Thus, when the mod
