Why do we prefer 2s complement over 1s complement ? Reason for this ?

Your Answer

To represent the negative form of binary no. the system we use is 2'S complement.if one no. is binary then its -ve no. will be 2's complement of that no.so 2's complement can be used to perform arithmetic operations of both +ve and -ve numbers .While in 1's complement is not used for negative integers however it can be used with arithmetic operation of natural numbers so we prefer 2's complement over 1's complement.
