Assignment Help:

Subtract -27 from 68 using 2's complements.

Ans. By using 2's complement 68-(-27)= 68-(-27)

2's complement representation of 68 = 01000100(64+4)
2's complement representation of - (-27) = 00011011 = + 27
11100101 =-27 in 2's complement
Here add 68 and 27
           68             0 1 0 0 0 1 0 0
        -(-27)        + 0 0 0 1 1 0 1 1

        --------------------------------------
            95           0 1 0 1 1 1 1 1 1

        ---------------------------------------

Means that is equal to +95.
