I'm not a mathematician, and I have trouble following the number-puzzles at the end. But this book was delightful, nevertheless. I enjoyed learning about early systems of writing numbers and the development of the number system we currently use. It's much more recent than I had realized! Little bite-sized chapters told in children's story form make this book easy to read. Not scholarly, but fun.
Following boys from around the world, you learn how they came to know math: learn to write numbers, add, multiply, etc. There are many illustrations, perfect for Book of Century entries.
The last few chapters are full of number puzzles we enjoyed working through—even if we did get many of them wrong! 🤣
Very fun presentation about the progression of mathematical thought and discovery, but in a challenging way that makes you think. The last two pages are all a quick succession of number puzzles told in story form. My particular edition of this book came with an insert that gives the answers to the puzzles, but those answers are not at all in the main text. If you have a child that loves to work out number puzzles, this is a great book for them.
