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

    110001 + 10011100 =>
    10000001 + 1011010 =>
    1100011 + 1111100 =>

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

    10000001 - 1111111 =>
    1101100 - 101001 =>
    10101110 - 1010010 =>

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

    - 11100000 =>
    - 100000 =>
    - 11010000 =>

  4. Convert the following numbers between the given bases

    hexadecimal 46 : decimal
    decimal 192 : binary
    binary 1110000 : octal
