you have to give the recorded multiplier........now -113 is smallest so will be multiplier..now convert the number into two's complement form and then apply short cut(appending zero at first and then 00->0 01->-1 10->+1 and 11->0 ) you will get the desired answer

0

@Navneet Kalra -121 is smaller? and please ellaborate the answer.

Assume the operands are in 2’s Complement. To decrement A by 1, lines K,Cn and B should be : K = 1 , Cin = 1 , B = 1 K = 0 , Cin = 1 , B = 1 K = 0 , Cin = 1 , B = 0 K = 1 , Cin = 0 , B = 0

Initially all flips-flops in the circuit are cleared to zero , what is the mod value of the counter ___________ I got – > 3 sorry for the poor image quality
