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

    10110000 + 110111 =>
    11111 + 1011100 =>
    11000010 + 111100 =>

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

    10001101 - 1010001 =>
    10011111 - 1100100 =>
    101110 - 100100 =>

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

    - 1100000 =>
    - 1110000 =>
    - 10011101 =>

  4. Convert the following numbers between the given bases

    binary 10000001 : octal
    decimal 226 : hexadecimal
    decimal 27 : octal
