Using 1's complement
a) The 1's complement of the subtrahend 11010 = 00101.
Therefore 01001-11010 = 01001 + 00101 = 01110
Since no overflow, we take the 1's complement of the result and it is negative.
Therefore the difference is -10001
b) The 1's complement of the subtrahend 11001 = 00110.
Therefore 11010-11001 = 11010 + 00110 =1 00000
Since there is an overflow, we add the overflow to the result
Therefore the difference is 00001
Repeat the same process for the others.
