Question

10)Subtract using 1's complement method 10111-11100​

Answer 1

Answer:

First, find the 1's complement of the negative number 1001. So, for finding 1's complement, change all 0 to 1 and all 1 to 0. The 1's complement of the number 1001 is 0110.

Now, add both the numbers, i.e., 1101 and 0110;

1101+0110=1 0011

By adding both numbers, we get the end-around carry 1. We add this end around carry to the LSB of 0011.

0011+1=0100
