Mathemagic

Sir Tzyphyr is a wizard with a difference. His strength comes from mathemagic, the magic of numbers, and he believes it can do far more than any ordinary spell. In this book he guides the twins Megha and Mehul on their second trip into his number-filled world.

This time the children focus on zero, a number that is easy to overlook but surprisingly mysterious. Along the way they learn about units, tens, thousands and the larger place values beyond, seeing how a humble zero changes what a number means. It is a playful way for young readers to get comfortable with how our number system works.
