    In two's-complement representation, positive numbers are simply represented as themselves, and negative numbers are represented by the two's complement of their absolute value Note that to get the two's complement of -9 start with 01001, which is just 9 in regular binary Then, since this is negative, invert all bits and add one 10110 + 00001 ________ 10111 This is the two's complement of -9. Now just use regular binary arithmetic with carries. 10000 (16) 10111 (-9) ___________ 00111 (7)
