Numbers are used in everyday life for many vital functions, from making scientific breakthroughs to equally dividing that last piece of pie.

Using fascinating experiments, funky illustrations, and easy-to-follow language, the book narrates the story of how the field of mathematics developed, and shows you why the world cannot function without it. What makes Pi one of the weirdest numbers in the world? How can you weigh your head without chopping it off? How can you build your own cool sundial? Find answers to these questions and much more as you go about becoming a whizz with numbers.

Flip through the bright and colorful pages of Why Pi? to discover how numbers enable us to explore, plan, and build just about everything.
