  1. Use the Web to find out how many countries are currently officially assigned a 3-digit ISO 3166 country codes. Which country has the highest numeric ID code number? How many bits are necessary to represent all assigned country ID numbers; why? [2]
  2. Perform the following calculations and indicate the result accurately in the base indicated. [3]
    1. 35278 + 2258 =
    2. A95E16 + 1D916 =
    3. 13234 + 33104 =

Please read carefully. Using minimum required number of bits in 2’s complement notation, perform 17110 – 6810 (subtraction by preserving addition). Show all the significant steps in your work by indicating the starting values, sign conversion and the addition operation aligning all numbers including the carry values in each position using the Courier New font. Indicate the final value in Base-10.
