Olive and Otto are then told to fix an odd problem. Usually, the problem is caused by a certain person, such as an Odd Squad agent or citizen that doesn't know what they are doing, but usually it is caused by a villain. Whenever Olive and Otto can't solve a math-related problem on their own, they get help from the Mathroom.
