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

    111111 + 1011100 =>
    11010 + 1010011 =>
    1110011 + 1010011 =>

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

    10001001 - 1110011 =>
    1111001 - 1010100 =>
    10110011 - 1000110 =>

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

    - 11000001 =>
    - 11101100 =>
    - 10000101 =>

  4. Convert the following numbers between the given bases

    hexadecimal BF : binary
    binary 11100 : decimal
    hexadecimal A6 : octal
