0 votes 0 votes P = 11101101 Q = 11100110 P-Q = P+(-Q) [Here (-Q) means 2's complement of Q] So, 2's complement of Q = 0001 1001 + 1 = 0001 1010 Now P + Q = 1110 1101 + 0001 1010 = 0000 0111 Answer is option (b) ushamya answered Aug 7, 2019 • edited Aug 7, 2019 by ushamya ushamya comment Share Follow See all 0 reply Please log in or register to add a comment.
