/edit: anecdotes and simplification are often a balancing act between between simplicity and (thorough) correctness. The opposite thing and enemy of enemy (in a two party premise) fit and practically correct for the Negation of the multiplication. It doesn’t thoroughly represent the multiplication part. But I think the negation is what you were looking for?
Can you explain negative multiplication is in this sense? Like
-1 * -1to make it simple?Edit: is it like
the enemy of my enemy is my friendtype deal?Yes, exactly. A double negation.
The opposite of the opposite is the same again.
