Ok, let's look at it this way. Then, what's the value of this lone sign bit? _Where_ does it have a value? There's not one bit that could give it a value, so it's 0, and constantly so. It doesn't need to be stored, so you can remove it. You can remove all single bit variables then. > When adding or subtracting, the ALU does not care about the type being > signed or unsigned.
