Moose and the Math Fairy (Hardcover) (ISBN-13: 9798988318736)

When the Math Fairy leaves Moose in charge for the day, he figures making one little change can't hurt. Who needs plus signs, anyway? And graphs can't be THAT important... But he soon discovers that making small changes can lead to big problems! From upsetting the Star Fairy to causing chaos in a pie factory, Moose's attempts to fix things only make them worse.

Join Moose on a magical journey as he causes problems, solves problems, and finally learns what makes math so mathematical after all.
