To find the 2's complement of a binary number, we first complement

To find the 2's complement of a binary number, we first complement (flip the bits: 0 to 1 and vice versa) then add 1 (arithmetic adding) to the resulting binary. For example, if 2 is 0010 then -2 is 1101 + 1 = 1110. What is the 2's complement of 121 (in other words, -121)? 1111 1001 1000 0111 0111 1001 1000 0110
