Just as a hint. If someone tells the answer to a dead mother or in time travel was the Paradoxum, than you will have to understand that he considers the question the answer. That person is so stupid that rephrasing the question into more detail is an achievement considered the answer, not just the very same issue in more detail.
Then, have a camera ready before you say: I see you understood the question. Now tell me the solution of the Paradoxum.
In mathematics they won't accept anything like: The equation is wrong. No matter that an equation is a mathematical statement asserting that two expressions are equal, indicated by an equal sign (=) logically means that some are not equal. You would not believe what sign exists for such situations. So simple.
