Answer 1

Answer:

For addition, the two numbers are presented to the adder from two registers A and B. The result may be stored in one of these registers or in the third. For subtraction, the subtrahend (B register) is passed through a 2's complement unit so that its 2's complement is presented to the adder (a – b = a + (-b)).
