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 |

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

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

Thank you @Sharanya. You made it in short and easy way! |

@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. |
