Question

Difference between 1's and 2's complement by giving example

Answer 1

Answer:

2's complement of a binary number is 1 added to the 1's complement of the binary number. ... Another difference is that while adding numbers using 1′ s complement, we first do binary addition, then add in an end-around carry value. But, 2′ s complement has only one value for zero, and doesn't require carry values.
