An imaginative introduction to number theory and abstract algebra, this unique approach employs a pair of fictional characters, Ant and Gnam. They put a variety of theories into action — applying linear diophantine equations to football scoring, using a black-magic device to simplify problems in modular structures, and developing intriguing modifications to the rules of chess. 1995 edition.
