I can't find anything there for my question. The question is like this:
NOT(10) = -11 -- That is fine and understanding
NOT(20) = -21 -- The same
But why is then: Not(10) AND Not(20) = -31?
-11 = &B1111111111110101
-21 = &B1111111111101011
AND ================
&B1111111111100001
-31 = &B1111111111100001
