Alice, Jimmy, Colby, and Sam are four good friends who share a common bond - they all hate math. As they complain about it on their way home from school, the King of Math appears and whisks Alice away. Jimmy, Colby, and Sam decide to rescue her, but to enter into the Math King's world they must first pass through 20 gates, guarded by 20 great mathematicians. Saving Alice hinges on the friends learning about the discovery of zero, Roman numerals, fractions, rational and irrational numbers, and much more-all in the context of an exciting, puzzle-based adventure.
