    Hearing Zhao Chen¡¯s question, the two children squatted down and started counting with branches.

    Fang Xuanling also frowned slightly and calculated quickly in his mind, but before he could finish the calculation, he saw the squatting child and stood up suddenly and answered: "270 bags."

    Zhao Chen touched their heads with a smile, and looked at Fang Xuanling again: "Lao Fang, didn't you brag that you could teach the current emperor's prince? Why, my question, you can't even calculate the speed of a primary school student.  Can¡¯t even keep up?¡±

    Fang Xuanling¡¯s eyes widened, how could this be possible?

    Li Shimin on the side also looked at the two primary school students curiously, only to see strange vertical columns on the ground above them.

    "Little doll, what are these?"

    A child said: "Vertical column calculation, didn't your teacher teach you?"

    Li Shimin's heart twitched, but he coughed: "What is this vertical calculation?"

    "Even for multiplication calculations, you can do it in one go using the multiplication table."

    A child looked at Li Shimin with wide eyes and curiosity: "Uncle, didn't your teacher teach you?"

    Calculation of multiplication?  Multiplication table?

    Fang Xuanling was also squatting down to study the child's calculation column at this moment. The more he looked at it, the more surprised he became!

    "This kind of vertical column calculation is much simpler and clearer! No wonder it is so efficient!"

    "Moreover, could it be that the symbols they write represent numbers?"

    Zhao Chen looked at Fang Xuanling with a smile: "Old Fang, are you convinced? If not, I will ask another question."

    Fang Xuanling was naturally dissatisfied: "If you are not convinced, continue to ask questions."

    "Okay, let me ask, if we throw an egg and a piece of wood into the water, why does the egg sink and the wood float?"

    Fang Xuanling was suddenly stunned.

    Damn it, why is this?

    Li Shimin on the side was also racking his brains. He suddenly realized that he didn't seem to know the answer to such a simple question.

    Yes, eggs will sink when thrown into water, and wood will float when thrown into water, but why?

    why?

    Fang Xuanling and Li Shimin both felt confused and couldn't think of anything after thinking hard.

    Could it be that it is heavier?

    And a child said: "I know, I know, I said in class that the reason is that the density of eggs is relatively high, so they sink, while the buoyancy of wood is less than that of water, so it floats."

    Density?  buoyancy?

    Li Shimin was confused, what is the principle?

    And Zhao Chen looked at Fang Xuanling and saw that Fang Xuanling still seemed unconvinced, so he couldn't help but continue to ask: "Then why can fish swim in the water, but people can't live in the water?"

    Fang Xuanling was thinking hard again, and a child replied: "Because fish have gills and fish bubbles in their bodies, they can breathe in the water. People have no gills and cannot breathe in the water."

    "That's so smart."

    Zhao Chen touched the heads of the two children and looked at Fang Xuanling again.

    At this moment, Fang Xuanling was stunned.

    "Lao Fang, do you accept it?"

    Zhao Chen was smiling, but Fang Xuanling felt like his mind was a little lost. Li Shimin on the side was also shocked.

    He found that the knowledge these little children learned seemed to be very different from them.

    It was at this time that the principal came over.

    "Mr. Zhao."

    The principal took out the account book: "Look, this is our school's bill expenditure last year."

    Zhao Chen opened it and looked at it. Fang Xuanling couldn't help but move closer. Only then did he realize that the account books used the same strange numbers as those of the students.  (Remember the website address: www.hlnovel.com
