This summer vacation, I read the book Mathematics Commander. This book is mainly about a child named Niu Niu, who is good at math. He won the first prize in a math contest and changed himself into a "math commander". Once, the 77 countries invited Niu Niu to attend an important meeting of the 77 countries. In order to recapture their own territory, the July 7th Kingdom launched a war against the August 8th Kingdom, and Niu Niu became the real commander in chief of mathematics.

As soon as Niu Niu came up, he outflanked and defeated the 88th kingdom. The 88th kingdom sent mechanical beasts, but the 88th kingdom was defeated by Niu Niu. Xiaoqi's adjutant designed to arrest Niu Niu, but Niu Niu used his mathematical knowledge to escape and disguised himself to know all the details of the 88 Kingdom. Niu Niu trained a circular queue and defeated the 88 Kingdom.

There is a problem-there are seven soldiers, 12 12. Count one. Let Niu Niu stand anywhere in the line, count one, see who can make it to the end, and then reward a bag of candy. Niu Niu stood in the eighth place and finally won.

All of us must learn math well, because math is very important. We often use mathematics in our life. Mathematics cannot be proud, because there is a saying: modesty makes people progress, and pride makes people fall behind. We should not be proud. Once we are proud, we will regress. We should be modest. Only in this way can we make continuous progress like Niu Niu.
