Discussion: The 2's Complement Representation is used in almost all modern computers to represent -ive numbers, in addition to +ive ones. Once you understand it well, please share here some insight or...

Properties of 2's complement:
1. In 2's complement arithmetic, subtration of one number from another or addition of a negative number to a positive number is identical to the operation of addition between unsigned numbers. That is, we do not have to take special care of the sign of numbers in arithmetic operations; they take care of themselves.
2. Using 2's complement notation, half of all numbers that can be represented using a certain number of bits are negative and the other half non-negative. A number is non-negative if its most significant bit is 0, negative if it is 1.
3. It is possible to represent a given number using extra number of bits. You just need to sign-extend...
