Exercise 3.29       (30 points)
Exercise 3.30       (20 points)
Exercise 5.2, 5.3   (15 points)
Exercise 5.29, 5.30 (15 points)
Exercise B.24       (20 points) (this is labeled incorrectly as 3.24
                    in the text.  It is in Appendix B, Page B-81).  
                    Also, despite what the text says, it might not be
		    easy to make the changes on a photocopy.  I would
		    start with a table of all the possibilities (operand1 ==
		    neg, pos; operand2 == neg, pos), listing what
		    operation is performed, whether overflow is
		    possible, etc.  Then, write a truth table and/or
		    implementation in GATES of the needed logic.
		    Check your answers on different cases, to show
		    your answer is correct.
