Unlock the mysteries of math and discover the wonder of numbers. From fractions to pi, and measurements to probability, kids will find out incredible information, such as why zero is so useful; how to tell time on Earth and other planets; how music, math, and space, are all connected and so much more!

With clear, commonsense explanations of mathematical concepts and fun and interesting applications, this book is a great way to increase an understanding of math. The concepts addressed include, but are certainly not limited to:
