Unformatted text preview: the number. a. Prove that the nine’s complement of a number plus 1 is equal to the ten’s complement of the same number. b. Use the nine’s complement plus one to calculate the values in Exer-cise 12 b, c, and d. c. Which did you find easier to use, the direct calculation of the ten’s complement or the nine’s complement plus 1? Justify your answer. 14. Evaluate the following expressions, where A is 00110011 and B is 01010101 a. A + B b. A ± B c. B ± A d. ± B e. ± ( ± A) 15. Is the two’s complement of a number always a negative number? Explain. 16. The one’s complement of a number is analogous to the nine’s comple-ment of a decimal number.
