An-bit binary adder can be used to perform an n-bit unsigned subtraction operation X – Y, by performing the operation X + Y + 1, where X and Y are n-bit unsigned numbers and Y represents the bit-by-bit complement of Y. Demonstrate this fact as follows. First, prove that  Second, prove that the clay out of the n-bit adder is the opposite of the bol TOW from the n-bit subtraction. That is, show that the operation X – Y produces a bol Tow out of the MSB position if and only if the operation  does not produce a cany out of the MSB position.
