SECTION I-10: 2's Complement of Binary Number

To get the 2's complement of a Binary number, invert all the bits and then add 1 to the result. Inverting the bits is simply a matter of changing all 0's to 1's and 1's to 0's. This is called the 1's complement. Example is demonstrated below.


Take the 2's complement of 10011101
