In this question, you are provided with two unsigned binary numbers, A and B. You are asked to evaluate (-A-B) as well as (-A+B) using the two's complement 12-bit number system. If the result is encoded in less than 12 bits (including the sign bit), you need to extend it to fill the entire 12 bits. If your answer is less than 12 bits or more than 12 bits, you will get zero. Indicate if an overflow occurred or not. N.B. You need to provide the entire 12-bit result, even if an overflow occurs. You MUST report the answer in 2's complement. Do NOT convert the number back from the 2's complement. Leave it in the 2's complement representation When A=10000101100 and B = 10111100100, the value of (-A-B) = expression, type yes, if not type no If an overflow occurred during evaluating this ; and If an overflow occurred during evaluating this the value of (-A+B) = expression, type yes, if not type no
