"Why is Zero?" Grandpa Xiangxiang asked in a rough voice, and what he said was the doubts that a group of parents were thinking about watching the fun.

Leilei held the pen given by his second uncle in his little hand and showed his aura. He drew two more circles on the paper for Grandpa Xiangxiang. Of course, Grandpa Xiangxiang couldn't understand it. The more he looked, the more confused he became. He thought the kid was fooling him, the old man, and stared at him and said, "If you have anything to say, duck eggs are duck eggs, why are you drawing two? Do you think I can't understand that the first one you drew was a zero?"

"These two circles, one represents the set of apples and the other represents the set of benches." Leilei's silly voice was clearer and louder in the car than any adult. "No matter how many of them each have, the bench is a set of benches, and the apples are a set of apples, and there is no way to intersect. So it is zero."

Grandpa Xiangxiang's soul was shaking by the sound of her baby's milk, as if she was about to swim into another world: "What, what is gathering, what is intersection?"

Looking closely, Grandpa Xiangxiang's old face turned red. Grandma Xiaogu looked at Grandpa Xiangxiang's blushing face strangely behind her as if she discovered a new world. I think this old man was more shameless than her when he first met her and dared to say anything. How could he know that he was blushing now?

It can be seen that Grandpa Xiangxiang felt that he was about to be at a disadvantage in front of this three-year-old child. An old man lost to a three-year-old child in terms of knowledge, which made him very ashamed. Because he is now comparing with a three-year-old child, not a college student.

Back then, children like Leilei who could speak math vocabulary that adults didn’t know were very few. After all, in that era, most families did not have the educational resources and conditions at all.

As the parents followed Grandpa Xiangxiang to discuss what the meeting was, Teacher Zhu got goosebumps all over her body, and her mouth sounded like "My God".

There is nothing wrong with the word "set" in mathematics. Not to mention other things, the symbol written by Meng Chenyi in the middle of the apple and bench will definitely be the majority of parents who have failed the exam. Because many parents are like Grandpa Xiangxiang, they have insufficient mathematics education due to historical reasons. Everyone can understand the plus sign. Many people probably look at it but have to put a question mark in their heads to ask what it is. The most terrifying thing is that this is a content of high school mathematics.

Besides, even if the child’s parents are top students, teaching children is another matter. Otherwise, professionals need to do professional things. Senior intellectuals need to ask Teacher Yu for their families to educate their children.

But this Meng family's second child is so amazing. She is admired by her academic master. Now even a three-year-old child can teach high school mathematics content. How can I describe this? Teacher Zhu's excitement was because even a famous kindergarten teacher like her, she could not do the Meng family's second child.

What is a real academic master? Teacher Zhu turned his head to Ning Yunxi with passion in his tone and said, "Your second son is called a real academic master."
