A textbook in disguise, this fascinating volume embraces both the math enthusiast and the clock-watching math victim holding his breath until the period is over. It’s not Alice in Wonderland, but it has that feel when Robert, who is no math wizard, has recurrent dreams of a number devil set on teaching him math concepts. In a series of 12 dreams Robert discovers the amazing world of numbers from the meaning of zero to numbers that expand without end. This international best-seller adds fun and adventure to math and teaches readers about logic in the process.
