Danny Chung does not do maths

Danny Chung is very unhappy that his grandmother (Nai Nai) is moving from China, and that he has to share his bedroom with her. He is also unhappy about having to keep Nai Nai company every day during the Easter holidays. However, when Danny needs to do some schoolwork for a mathematics project, he discovers that Nai Nai has brilliant mathematics skills, which combine really well with his art skills. By having to take care of his grandmother, Danny begins to learn about many different things in life, and he eventually gets to know himself better as well.
