A negative-binary adder-subtracter

The logical design of an adder-subtracter for negative binary numbers is described. The twin-carry generates during the addition, is converted into a single hybrid-carry-borrow, this helps to design a circuit which can function as an adder or a subtracter with a simple switching control.
