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

    111101 + 1101111 =>
    1111 + 11100111 =>
    10100011 + 100 =>

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

    1001111 - 10101 =>
    10100101 - 10011 =>
    11111010 - 111 =>

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

    - 10110010 =>
    - 11010101 =>
    - 10101110 =>

  4. Convert the following numbers between the given bases

    octal 17 : binary
    octal 331 : hexadecimal
    hexadecimal F7 : decimal
