0 - 1 = 11 in Binary? No it isn't. You need more description of the process to make such a statement.

Attaching a sign is a whole different animal.

1) You'll have to read up on the "twos compliment", and

2) Some results are VERY curious if you have an insufficient field in which to hold your data. Unintended trunctation can be difficult to track down.
