Perform the subtraction operation, X - Y, in 8-bit binary using the 1's complement and 2's complement, for the following X and Y pairs:

Note: change these decimal and octal forms to 1's complement or 2's complement. Don't forget to do each point in 2 ways: 1s complement and 2s complement

a. X = (81)10, Y = (50)10 b. X = (3.375)10, Y = (5.8125) 10 C. X = (21), Y = (7)
