Perform the following, using 1's complement math. You must use the A-B = A+(-B) form of subtraction. All numbers are already in 1's complement form. Remember that in your computation, you may have to extend the sign of the numbers so that both top and bottom number have the same numbers of bits. Your answer will be represented in the same number of bits as the problem. EX. Problem (a) uses 5 bits. Therefore your answer will be represented in 5 bits. (a) 10011 - 10010 = 10011 base 2 01101 base 2 00001 base 2 (b) 1001 - 110101 111001 base 2 + None of the above 000100 base 2 (c) 100010 - 100110 = 100010 base 2 + 011001 base 2 = 111011 base 2 (d) 101000 - 10101 = 101000 base 2 + 001010 base 2 110010 base 2
