I will go away with my tail between my legs if someone can show me that our esteemed mathematics library already contains de Morgan's laws for booleans. I also added a docstring. I can't lint the file because it's so high up in the import heirarchy, but I also added a docstring for the two instances.

For reference, de Morgan's laws for Props are in logic.basic.

Could you add docstrings or a module doc that mentions "de Morgan's laws"?
