A Mathematical Adventure in learning for both adults and children that turns numbers into ideas and ideas into adventures.
Twelve-year-old Robert hates his maths teacher. He set his class boring problems and won't let them use their calculators. Then in his dreams Robert meets the Number Devil who brings the subject magically to life, illustrating with wit and charm a world in which numbers can amaze and fascinate, where maths is nothing like the dreary, difficult process that so many of us dread. The Number Devil knows how to make maths devilishly simple. Full colour illustrations are included throughout.
