a. Obtain the 9's complement of the following eight-digit decimal numbers: A=90009951; and B=00980100 b. Obtain the 10's complement of the following eight-digit decimal numbers: A=90009951; and B-00980100 c. Suppose that we use the 10's complement of X to represent -X. Show that A-B can be performed as A+ (-B); i.e., by taking the 10's complement of B and adding it to A (and ignoring the carry out of the 8-digit decimal values).
