Overview
Two's complement is the most common signed integer representation scheme on computers. The scheme widely used because a computer can use the same circuitry to perform addition, subtraction and multiplication, whereas otherwise they would have to be treated as separate operations. Also, two's complement has no representation for negative zero, and thus does it not suffer from associated difficulties.
