Perform the following operation in binary:
15X-7
I tried getting help on the engineering board, but nobody has helped yet, so I figured I would try over here...
- I can't seem to figure this one out for some reason. My first attempt, I used 1111(15)X1001(2's complement of 7), but I can't get the right answer. I believe that the answer should come out to be the 2's complement of 105 since the actual answer is -105, but I can't get that. Please help.
