the following binary numbers are all represented using 6 bit signed 2's complement. all addition should also be conducted in 2's complement form. A=111000; B=010110
(a) what is A's value in decimal?
(b) what is B's value in decimal?
(c) D=A-B what is D in 6 bit signed 2's complement form? is there overflow ? (Hint find B* first, then calculated D=A+B*)
