CMPE-240: Hexadecimal Homework 1 -- conversion and addition


Instructions:
    1. All signed value are 7 bits wide and unsigned values 8 bits wide.
    2. Provide hexadecimal values in 0x... format (C language format)
    3. Leave your answer (with reasoning where appropriate) underneath
       the question. This is where you show your work.
    4. Submit your answers (i.e., in this text file) to MyCourses
       Dropbox: "Homework 1".
    5. All questions are worth one point except 6 and 7 are worth two points for a total of 10 points.
