  1. Perform binary addition on these binary numbers...

    110101 + 10110 =>
    10010001 + 111011 =>
    110000 + 100101 =>

  2. Perform binary subtraction on these binary numbers. Assume 8 bit two's complement representation.

    10111000 - 110000 =>
    101101 - 11011 =>
    11000101 - 1000110 =>

  3. Negate the binary numbers shown.
    Assume 8 bit two's complement representation...

    - 10110 =>
    - 10111110 =>
    - 10101011 =>

  4. Convert the following numbers between the given bases

    binary 10000011 : octal
    decimal 218 : hexadecimal
    hexadecimal 54 : decimal
