This fifth volume in the Manga Math Mysteries series features a puzzle dealing with a formula for jow, a Chinese medicine for kung fu students; this particular formula was created long ago by Sifu Leung, and Sifu Faiza's grandfather wrote it in code in his journal, which has been entrusted to Joy. The students try to figure out the formula using fractions, but they realize some parts are missing. This series helps show how people use math every day along with presenting some fun mysteries and character lessons with lively, colorful illustrations.

The adventures of the kids in Sifu Faiza's kung-fu school continue in these cartoony graphic novels. In Ancient, the friends utilize fractions to find the lost formula to an ancient medicine. In Fishy, the students use multiplication and division to figure out who dumped chemicals into the school's fountain. The math problems and methods are shoehorned into the stories.
