for (11) --> 1011
1's Com (11) --> 0100
2's Com (11) --> 0101
for (2) --> 0010
1's Com (2) --> 1101
2's Com (2) --> 1110
Add 2's Comp (11) & (2)
0101 + 1110 --> 10011 --> last digit carry so eliminate -->0011
for negative sign we can use 1.
so the ans is
1111 0011
1's Com (11) --> 0100
2's Com (11) --> 0101
for (2) --> 0010
1's Com (2) --> 1101
2's Com (2) --> 1110
Add 2's Comp (11) & (2)
0101 + 1110 --> 10011 --> last digit carry so eliminate -->0011
for negative sign we can use 1.
so the ans is
1111 0011
(2)

@Kimsy it's not that easy & @ Sharanya you explained it wrong.
We have to add 2's complement of (-11) and (-2). But Sharanya explained the simple addition and then 2's complement of the result.

For negative sign we use only one 1. Then how did you said @Kavi? please explain me?

It is simple. -11+(-2)=-13. So taking 2's complement for -13, we get, 1111 0011.
