  4. In the duodecimal system, find

    1. the largest single-digit symbol (following the practice of hexadecimal A-F)
    2. the range of decimal numbers that can be represented by three duodecimal digits.
    3. the duodecimal number corresponding to 55.7510

  5. Find

    1. the range of unsigned decimal numbers that can be represented by 10 bits
