What is the representation of negative numbers in binary?

In binary representation, negative numbers are typically represented using a system called two's complement. In this system, negative numbers are represented by flipping the bits of the positive number and adding 1 to the least significant bit. For example, in an 8-bit system, the positive number 5 is represented as 00000101. To represent -5, the bits are flipped to 11111010 and then 1 is added, resulting in 11111011. This representation allows for easy addition and subtraction of both positive and negative numbers in binary form. The most significant bit in the binary representation serves as the sign bit, where 0 represents a positive number and 1 represents a negative number.
