Ones Complement
In ones complement, you are expected to:
1. convert the number to binary
2. extend to the number of bit representation (for example, if the question says 8-bit representation, you ensure that you extend to 8 bits)
3. flip the bits (that is, change the 1s to 0s and the 0s to 1s)
For example:- Convert 9010 to its 8-bits ones complement representation.

Right now the number is represented with 7 bits. Therefore, only one bit needed to have an 8- bit representation. Always extend on the left and NOT THE RIGHT. Example, 3410 is the same as 03410; 10012 is the same as 010012. Get the point? | |||||||||||||||||||||||||
