"This is the best math book"--found out because of the need

This column is mainly about the popular science books of a famous Japanese mathematician, which mainly deals with mathematical antiquity, modern history and some methods of learning maths, and also involves some simple and interesting small topics. As the cover of the book says-"Reading mathematics, the ins and outs, you can understand the root of the essence of mathematics, from 0 to 1, let you realize that all the math is because of the needs of people to produce", this will undoubtedly greatly shorten the distance between mathematics and us, so that we can stimulate a greater interest in studying mathematics, This is perhaps the most valuable thing that this book can bring to us.

For the first chapter-mathematics, because of the need to find, the author outlined the ancient history of the origin and development of mathematics, traceability to what extent, cuneiform said the number ... From the point of view of mathematics itself, the author explains this history mainly from the two main lines of algebra and geometry. In introducing taught's Algebra Master drop chart, there is a small headline that is really worth our attention: simplification is for trouble. This reveals why we define "seemingly" irrational, abstract mathematical symbols in order to facilitate the argument for more complex problems.

Here are two simple minor topics:

Robert Moth Problem:

There are three books A, B, C on the shelves, known each book cover 1cm, the book thickness 3cm, then the first page of a and the last page of C was a hole in the worm, then how long is this hole?

In fact, when we consider how to list the addition formula, we should think about how the three books are placed.

Robert Snail Question:

A snail climbed the flagpole of 300cm, climbed 120cm during the day, the night slipped 60cm, asked the snail the first few days to reach the top of the flagpole?

It is important to note that the snail does not need to consider the 60cm of the night after the top.
