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...

    1010 + 110011 =>
    111101 + 111000 =>
    10101111 + 1001000 =>

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

    11110100 - 10000011 =>
    11011010 - 1110100 =>
    1011110 - 100011 =>

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

    - 11101111 =>
    - 100 =>
    - 1110101 =>

  4. Convert the following numbers between the given bases

    octal 252 : decimal
    octal 202 : binary
    decimal 21 : octal
