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

    10011 + 10000010 =>
    11100 + 10100011 =>
    11101 + 10011100 =>

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

    11110 - 110 =>
    1101100 - 1100010 =>
    11011111 - 10001111 =>

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

    - 11011 =>
    - 1001101 =>
    - 1010011 =>

  4. Convert the following numbers between the given bases

    octal 334 : hexadecimal
    binary 110110 : octal
    hexadecimal 9D : decimal
