Say I’m going to subtract:
0000 0000 – (-1)
that is: (two complement)
0000 0000
- 1111 1111
---------
= ???? ????
Whats gonna happen, my brain is really f***ing with me right now, it went perfectly fine before, I think its the overflow thats screwing me up, can someone give some clearance on this please :)?
Take the two’s complement of the subtrahend and add it to the minuend.
