Miranda Bloom, the mathematical prodigy first introduced in Geek High returns in another novel for teenagers, this time emphasizing her participation in mathematical competitions. For instance, we see her answer a question about how long it will take a tank to fill with water if the water pours in at a constant rate but water leaves a drain at a rate proportional to the amount in the tank, which she incorrectly refers to as a "partial differential equations" question (it involves an ordinary differential equation.) No clue is given as to how she solves it, so there is no way for a reader to learn anything about the math that she is using. However, along with Miranda, the reader may learn to have just a bit more appreciation for math than the passive dislike expressed by Miranda at the start. And, in any case, the math is not the main focus of the novel, which has more to do with boys and other teenage stuff.
