Program Plan Intro

a.

Hexadecimal addition:

  • The basic rules for adding two numbers are given below:
    • Read the two numbers to know the number of bits.
    • If the number of bits is less than the other number, then pad the required zeroes.
    • The numbers are represented in bytes (1 byte = 8 bits).
    • Align the numbers in order after padding.

Explanation of Solution

b.

AE9 + F:

  • Start with the numbers from right to left.
    • The equivalent hexadecimal value for F is 15. Add 9 + 15 which gives 24. The equivalent hexadecimal digit for 24 is 18. Hence, write 8 below and add carry as 1...

Explanation of Solution

c.

1066 + ABCD:

  • Start with the numbers from right to left.
    • The hexadecimal value for D is 13. Add 6 + 13 which gives 19. The equivalent hexadecimal value for 19 is 13. Write 3 to the result and add carry as 1.
    • The hexadecimal value for C is 12. Add 6 + 12 + 1 which gives 19. The equivalent hexadecimal value for 19 is 13. Write 3 to the result and add carry as 1...
