What is Two's Complement?

Two's complement is a numerical representation method used in digital electronics, computer science, and programming to represent signed integers in binary form. In this system, the most significant bit (leftmost bit) represents the sign of the number, with 0 indicating a positive number and 1 indicating a negative number. To represent negative numbers, the two's complement of the positive number is taken by inverting all the bits (changing 0s to 1s and 1s to 0s) and adding 1 to the result. This allows signed
integers to be stored and manipulated using the same hardware and operations as unsigned integers, simplifying arithmetic calculations and enabling the representation of both positive and negative values within a fixed number of bits.
