The method of complements is a technique used in Mathematics to subtract one number from another using only addition of positive numbers. There are two forms, the 1s complement and 2s complement of a binary number. The 1s complement of a binary number is the value obtained by inverting all the bits in a binary number. That is swapping 0s for 1s and 1s for 0s. The Twos' complement is a system in which the negative numbers are represented by the two's complement of the absolute value. The Two's complement is the way the computers understand and represent integers. In a two's complement, the most significant bit is 1, so the value represented is negative. The two's complement of a negative number is the corresponding positive value.
