Special feature

A variety of elaborately crafted problems, including shape, calculation, logic, and probability puzzles.
The key to math puzzles isn't computational ability.
It requires not the ability to do complex calculations, but rather the ability to think logically and flexibly, to 'change one's thinking'.
In this book, "80 Math Puzzle Masterpieces," problems that can make good use of the characteristics of these math puzzles have been carefully created using forms such as shapes, calculations, logic, and probability.
You can experience the true fun of math puzzles through problems composed in various formats.


Clear, logical explanations of the problem-solving process.
Math puzzles lose much of their meaning if you don't clearly understand the process of getting to the answer.
If you want to upgrade your math brain through math puzzles, you shouldn't give up on solving the problem and just look at the answer.
There are critical points that must be overcome in the process of reaching the correct answer, and the process of thinking about those points on your own upgrades your mathematical brain.
The 'Answer Explanation' for "Math Puzzle Masterpiece 80" clearly explains the solution points of the problem, helping you realize for yourself which part has a logical background.

Full-color illustrations clearly show the core of the problem and answer.
A clear picture is worth a hundred words, but it makes the point more clear.
Newton's top-notch illustrations, imbued with his long-standing expertise, are fully demonstrated in "80 Math Puzzle Masterpieces."
By explaining the core of the problem and the answer with elaborate pictures, you can visually understand the meaning contained in the math puzzle.


The identity and applications of prime numbers: puzzles and rules
A prime number is a number that is divisible only by 1 and itself, such as 2, 3, 5, 7, 11, etc.
Although its existence has been known since ancient times, its mysterious properties have not been fully revealed to this day.
We introduce the various characteristics and applications of prime numbers, which are deeply involved not only in mathematics but also in our daily lives.
This is because there are only a few people who can safely use online commerce.
We will learn about the principles by which prime numbers are used as cryptography and the problems mathematicians have been tackling to date, along with examples of applications related to prime numbers.
