Do you remember how to do division? Maybe, although it may have been a long time since you did it by hand. And a square root? This book isn't about how to do them, but about what they're for and why they work, since we've been conditioned to memorize procedures and not to ask questions. Mechanically performing operations is crucial for focusing on fundamental ideas that often go much further, both when learning to multiply and when solving problems; however, it can never be the ultimate goal of teaching mathematics. In today's world, reasoning is much more important than applying procedures; mobile phones and their apps have won us that battle, fortunately. Humanity has spent thousands of years using and perfecting tools to do the most tedious part of mathematics. Who would want to remember the math they left behind in school? Furthermore, it blends reflection on the history and tradition of mathematics with the dissemination of the most current ideas on its teaching, without straying —too far— from the school curriculum.
