Unformatted text preview: a. four bits. b. five bits. c. six bits. d. seven bits. 8. Although you have been computing simple arithmetic operations since the second grade, take the following small test to confirm that you thoroughly understand operations on signed integers. Evaluate the following expressions, where W is 17, X is 28, Y is ± 29, and Z is ± 13. a. X + Y b. X + W c. Z + W d. Y + Z e. W ± Z f. X ± W g. Y ± W h. Z ± Y 9. Use the base-ten number line to prove the solutions to the following operations, where A is 5 and B is ± 7. a. A + B b. A ± B c. B + A d. B ± A 10. Given a fixed-sized number scheme, where k in the formula for the ten’s complement is 6 (see page 59), answer the following questions....
