Answer 2

Answer: None is the solution, so. The solution is Option D.

Explanation: The subtrahend has five bits, whereas the minuend has six. By placing a "0" in the sixth position of the subtrahend, we can equalize the bit count between the subtrahend and the minuend.

Now, (101101 plus 1), or 101010, is 010110's 2nd complement. By using the minuend, add this.

 110110

The complement of subtrahend is 1 0 1 0 1 0 2.

 Continue with 1 1 0 0 0 0 0 as the result of adding

Dropping the roll over results in a subtraction value of 100000.

11010 has a 2's complement of (00101 plus 1), or 00110.

The counterpart of the number two is - 0 0 1 1 0.
