The world turns into mathematicsNumbers are not simply used to count the number of things, but also to measure the size and amount of something. Measuring something like this is called measurement. If you can not make measurements, you will not be able to plan or build experiments, nor will you be able to explore the world or make scientific progress. We will go back to the era when mathematics and measurement began in this book to meet people who have used the magic of numbers to understand the world and reveal the secrets of the universe. I hope this book will help children understand math as simple as magic.
