The story is set in ancient India and follows a boy named Bhagat who wants to bring his family out of poverty by winning a place in the rajah’s court as a singer. As it turns out, when it’s time for Bhagat to find a place to stay in the city, he is faced with a mathematical puzzle. He must pay the innkeeper one ring per night in advance, and it costs one coin to break one link in his chain of seven. But Bhagat only has a single coin, and he doesn’t know how many nights he will need to stay. How can Bhagat find a way to divide the chain of seven rings in order to pay one ring per night and avoid overpaying? His inventive solution offers readers a friendly lesson in binary numbers--the root of all computing.

In USSR this used to be a staple/ a must in High school Soviet curriculum. I think this statement alone is a testament to USSR'S and author's supremacy and primacy in Math culture. This is very essential to a thorough and no-nonsense math foundation for students. If you are a puzzle freak you will recognize many problems, if not most.
Long ago in India, there lived a raja who believed that he was wise and fair. But every year he kept nearly all of the people's rice for himself. Then when famine came, the raja refused to share the rice, and the people went hungry. Then a village girl named Rani devises a clever plan.

January 1, 2001, will mark the beginning of a new thousand-year period on earth. But our earth is more than four billion years old, and humans have lived on our planet for perhaps two hundred thousand years. So how can it be the year 2000? The answer is that it is the year 2000 only on the Gregorian calendar. On the Hebrew calendar, the year will be 5760. On the Muslim calendar, the year will be 1420. And on the Chinese calendar, it will be 4698. So what year is it really? It all depends on what calendar you use and when you started counting the years.

William Playfair was a dreamer and a joker. He saw the world differently from most and wasn’t one to always follow the rules. The scientists of his day believed in numbers and formulas, and turned up their noses at his zany idea to present data visually. But Will was sure that his line graphs, bar graphs and pie charts would help people understand information more easily. And now, more than a hundred years later, graphs can be found everywhere, from science journals to kindergarten classrooms! Lines, Bars and Circles is a playful introduction to a little-known original thinker and the fascinating story of modern infographics.
