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

    10100011 + 1000 =>
    1001001 + 1001101 =>
    1110 + 1010111 =>

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

    11011111 - 1101000 =>
    10111110 - 10100110 =>
    1101111 - 110011 =>

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

    - 1010011 =>
    - 11100101 =>
    - 1010101 =>

  4. Convert the following numbers between the given bases

    decimal 11 : octal
    octal 134 : binary
    hexadecimal 36 : decimal
