Two's complement
Two's complement is a mathematical operation on binary numbers, and is an example of a radix complement. It is used in computing as a method of signed number representation. The two's complement of an N-bit number is defined as its complement with respect to 2N; the sum of a number and its two's complement is 2N. For instance, for the three-bit number 0102, the two's complement is 1102, because 0102 + 1102 = 10002 = 810 which is equal to 23. The two's complement is calculated by inverting the bits and adding one.
