#2s complement

In digital electronics and computer systems, Twos complement calculator is a mathematical operation used to represent signed binary numbers. It's a way to represent both positive and negative values using a fixed number of bits.

Here's how it works:

For an N-bit number, the most significant bit (MSB) represents the sign bit (0 for positive, 1 for negative). The remaining N-1 bits represent the absolute value of the number in binary.

To get the two's complement of a positive number, you simply make all the bits the same.

To get the two's complement of a negative number:

Take the absolute value of the number and represent it in binary

Invert all the bits (flip 0s to 1s and 1s to 0s)

Add 1 to the inverted value

This allows both positive and negative numbers to be represented and arithmetic operations like addition and subtraction to be performed using the same logic circuits.
