Ones complement = Inverting all the bits in binary Twos complement = Ones complement + 1 48 in binary is = 00110000 Twos complement of -48 is = 11010000 80 in binary is = 01010000 Twos complement of -80 is = 10110000 So, -48 - 80 is 11010000 10110000 ----------- 10000000 ----------- As the MSB is 1. We can say that the answer is negative. and Overflow = 1
