"Mayer's vibrant, computer-generated illustrations, replete with gigantic otherworldly grins and mortal eyes stretched tall with fear, will appeal to fans of afternoon cartoons. Outlandish shadows convey the cautionary nature of the tale, while amusing details keep the mood perpetually fun. Narrated in humorous verse, this 'tale of mathematical mayhem' will provide an entertaining addition to math classes and a useful warm-up to tutoring sessions with less-than-enthusiastic students."--School Library Journal
