Hello-

I am working through the MBT questions and was wondering if a "chain logic" for example X -> B -> C -> D contrapositive is just the "inverse of the logical chain" making it /D -> /C -> /B -> /X

I realize that is kind of hard to read, but basically.....

if X then B then C then D

contrapositive would be:

if not D then not C then not B then not X
