More Sideways Arithmetic From Wayside School is the fifth novel in the Wayside School series of novels by Louis Sachar. Like Sideways Arithmetic From Wayside School before it, the book resembles more like a puzzle book with a Wayside theme than a novel about Wayside. According to the book's introduction, it was created as a response to Sideways Arithmetic after receiving complaints by students and teachers over the inclusion of the logic puzzles in the story.
