Best ResponseYou've already chosen the best response.0In two'scomplement 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)
