For obtained the first complement two steps are required.

1. Replace 0 to 1.
2. Replace 1 to 0.

E.g 100 to 011.

Simple rule for complements is that : Replace 1 by 0 and 0 by 1.

Eg: 1's complement of 1001 will be 0110.

In one's complements of a binary number, the easiest method is just replace 1 by 0 and 0 by 1. Thats all.

Anuj Goyal said:   5 years ago
Is it necessary for the number to be in binary digits for finding complements? Please anyone explain.

Yes it is a very easiest way to remember for all that the replacement of 1 by O & viceversa.

For 1's complement we change 1=0 and 0=1.

And for 2's complement we add 1 in 1's complement.

@Ashok.

In binary representation 5 is 101.

So, complementing the bits we have 010 i.e. 2.

Urvashi said:   1 decade ago
I agree with @Arunima. I would have marked none of these since I took it to be decimal 10.

Gautam said:   2 years ago
10 in binary form is -1010.
its 1's complement will be -0101.
Then how the answer is -01?
