About the story of arithmetic, there are bears, monkeys, old goats, foxes, weasels, tiger kings, snakes and little gray rabbits. The first big story is the one-eyed wolf king, which mainly tells the bad things done by the fox and the one-eyed wolf king. The second big story is Inspector Monkey. He told me that Little Monkey became a big detective because he was particularly good at math and solved many cases.

The third big story is the duel between the tiger and the bear. It is said that a stupid bear and a little monkey, a group of them competed with the tiger and fox, one set against five games, and finally the stupid bear defeated the tiger and fox 3-0 with the help of the little monkey. The fourth big story is "A tiger's ass can't be touched". It tells the story of many things that happened to the little mole when he traveled. He used mathematics to solve various problems and solved two or three cases.

The last big story is about a man who broke into a wolf's den. It is said that two wolves took the son of the old goat, and the little monkey tried his best to help the old goat save the little goat. After reading this book, I think the math story in it is really wonderful. Little monkeys are the cleverest, wolves and foxes are the bad guys.
