The day before yesterday, the math teacher came to our class with a bad smile. The teacher took advantage of our blink of an eye to write a five-star puzzle on the blackboard, "It is said that it can increase our intelligence". The whole class immediately moved from the noisy "vegetable market" to the quiet library, and the whole class held their breath and thought hard. One minute passed, two minutes passed, three minutes passed ... Suddenly, a weak voice broke the classroom, and even the sound of birds flying gently could be heard. "I will, teacher." When I saw that it was "Xiao Kongming", I couldn't help but feel a cold sweat for him and thought, "Why didn't Shi Junxian, who has always been regarded as a mathematical genius, think that he could do it?" The teacher smiled and said, "What's your solution?" He took his time to tell the way to solve the problem. When he finished, we applauded as if we had agreed, praising one after another. ...
This is my little friend, my pistachio, and this is "Little Kongming" Kun Qinghao from Class 4, Grade 6.
