The principle is that of ordinary addition; however remember the highest number is 1. Calculate the following: 11001 + 11010 Answer: 11001 + 11010 110011 Subtraction of binary is difficult, however uses 2 compliment it is easier.
Calculate the following: 110011- 11010 Answer: Step One: Invert 11010 and add 1 11010 -> 00101 + 1 = 00110 Step two: Replace -11010 with 00110 and add 110011+ 00110 Step three: Remove msb = 110012
