In electronics, a subtractor is a digital circuit that performs subtraction of numbers, and it can be designed using the same approach as that of an adder. The binary subtraction process is summarized below. As with an adder, in the general case of calculations on multi-bit numbers, three bits are involved in performing the subtraction for each bit of the difference: the minuend (X_{i}), subtrahend (Y_{i}), and a borrow in from the previous (less significant) bit order position (B_{i}). The outputs are the difference bit (D_{i}) and borrow bit B_{i+1}. The subtractor is best understood by cons
