Book description

Welcome to the amazing world of math—made just for kids like you!

Are you between 8 and 12 years old? Then get ready—this book is your gateway to unlocking the true power of math!

Regular numbers represent positions—called points—on a number line. Yet modern, widely used touchscreens suggest that selecting a point on a surface is more intuitive and fundamental than selecting one on a line. This shift makes the study of surface numbers more engaging and appealing, as it invites motion and interaction that bring math to life. Complex numbers, as it turns out, are precisely these surface numbers.

The author's research has redeveloped complex number theory from the ground up, making it accessible across broader educational levels—including elementary schools.

Inside, you’ll discover fresh, exciting ideas that turn tricky, mysterious topics into pure fun. If you’ve ever felt bored by textbooks or overwhelmed by endless numbers and tiny details, you’re not alone. That kind of math can drain your curiosity and make learning feel like a chore.

But this book is the total opposite—it’s a thrilling math adventure! Instead of sinking in a sea of numbers, you’ll hop aboard a sailing boat and chart your own course. With big-picture thinking, creative approaches, and motion illustrations that bring math moves to life, you’ll explore page by page, step by step.

Along the way, you’ll:

• Dive into real-life examples and clever metaphors
• Pick up awesome math tools
• Discover new concepts naturally
• Build confidence as you go

By the end of your journey, you’ll be amazed at what you’ve accomplished: mastering the number line, number grid, and the four key math moves—like adding and multiplying—that form the foundation for all your future math adventures!

So, are you ready to blast off? Flip the page, unlock the fun, and shout: “Math rocks!”

Author

Dr. Qiujiang Lu is an independent researcher and software developer in Silicon Valley whose work has re-created the imaginary unit in real life from first principles, which remained unknown for 500 years since the inception. His past research had involved discovering the mechanism of ice crystal growth habit change, an outstanding problem for more than 50 years in cloud physics that is closely related to the “thousands’ variations” in snowflakes. His interests are in physics, mathematics, software, and their multidisciplinary applications.
