Two's complement is a clever way of storing integers so that common math problems are very simple to implement. To understand, you have to think of the numbers in binary. It basically says, 1  for zero, use all 0's. 2  for positive integers, start counting up, with a maximum of 2 (number of bits - 1) -1.or example: 100101 itâs 1âs complement is 011010 and 2âs complement is 011010+1 = 011011 (By adding one with 1's complement) For more information this article explain it graphically.
