Practical on Binary Arithmetic and radix conversion 1007ICT

The aim of this practical exercise is to re-enforce the material related to the addition and subtraction of binary numbers, the representation of negative numbers, and the conversion from one representation to another.

The following is a randomly generated exercise and is different for each user.

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

    1100000 + 110100 =>
    110101 + 10101100 =>
    1011110 + 110101 =>

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

    11010000 - 10110011 =>
    10001010 - 1110100 =>
    1110001 - 10110 =>

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

    - 0 =>
    - 11111 =>
    - 101000 =>

  4. Convert the following numbers between the given bases

    decimal 207 : hexadecimal
    decimal 121 : binary
    binary 110011 : decimal
