The advantage of 2’s complement system is that _________(a) Only one

1.	The advantage of 2’s complement system is that _________(a) Only one arithmetic operation is required(b) Two arithmetic operations are required(c) No arithmetic operations are required(d) Different Arithmetic operations are requiredThis question was posed to me in an online quiz.My question is taken from 1’s, 2’s, 9’s & 10’s Complements in section Number System and Codes of Digital Circuits
Answer» Right ANSWER is (a) Only one arithmetic operation is required To ELABORATE: The ADVANTAGE of 2’s complement is that only one arithmetic operation is required for 2’s complement’s operation and that is only addition. Just by adding a 1 bit to 1’s complement, we get 2’s complement.
