I recently did a class about books for all ages that include fun math ideas, and discovered this book a day too late to include it, but this is a fun story that tells about the binary number system in a clever way.<\/p>\n

In ancient India, Bhagat is going to the capital to audition for the royal troupe, but all he has for the journey is one rupee and a chain of seven golden rings, the last of his mother\u2019s wedding necklace.<\/p>\n

He finds a place to stay in the capital city, and they will charge him one gold ring for a night\u2019s stay. Bhagat doesn\u2019t know how many days it will take him to be called to audition for the king. He doesn\u2019t want to pay all seven rings if he gets called sooner.<\/p>\n

Then he finds a goldsmith who will break a ring for him to separate it from the chain \u2013 but he will charge one rupee to break one link, and Bhagat only has one rupee.<\/p>\n

The clever solution is that he has the goldsmith break the third link in the chain. Then that ring is separate, and he\u2019s left with two chains, one with two links and the other with four. He is able to get the exact amount owed each day from one to seven days.<\/p>\n

There\u2019s an unexpected end to the story, and then an Author\u2019s note explaining the binary number system and how it relates to the story.<\/p>\n

I love this simple and visual approach to teaching binary! The story that goes with it will make it all the more memorable, and I love that the author set up a situation where this idea really did solve a problem.<\/p>\n
