When it comes to fighting, Zhu Yuanzhang thinks very highly of himself.

But this counts, he can't.

"Bowen, why is this problem so difficult? Can you solve it?"

Zhu Yuanzhang asked Liu Bowen for help.

Liu Bowen smiled and said: "Sir, Mr. Su's question actually comes from Sun Tzu's calculation of scriptures, and the algorithm is not difficult."

"Two times is enough to reduce the head, and the remaining half is called a beast; ride the beast four times, and reduce the foot, and the remaining half is called a bird."

"So there are four chickens and six rabbits."

When Zhu Yuanzhang heard the answer, he calculated it silently and said with a smile: "Sure enough, Bowen is a great talent!"

Liu Bowen replied: "It's just that I happened to see my grandson doing sutras, it's nothing."

"It's just that this kind of problem is a bit too difficult for these children."

Although Liu Bowen saw the answer at a glance, he also knew that Sun Tzu's knowledge of calculus was not something these children could understand.

While the two were talking, Su Jing's teaching continued.

"It seems that no one can answer it."

Su Jing looked around at the children and continued: "Actually, everyone can do it hypothetically."

"There are ten heads in total, which means the total number of chickens and rabbits is ten."

"If there is only one rabbit, then one rabbit has four legs, and nine chickens have eighteen legs. A total of 22 legs, which is less than 32 legs."

"So keep assuming."

Su Jing's method is actually not a good one, it's just exhaustive.

But for these children, it is very appropriate.

Similarly, Zhu Yuanzhang sounds more straightforward and easy to understand.

"Master Su is really good at teaching students."

Liu Bowen was a little emotional. He saw and heard clearly, and he admired him even more.

Time passed and Su Jing's class came to an end.

"Okay, that's it for today's class. Before get out of class ends, I leave you with a question."

"If there is a chessboard, one grain of rice is placed on the first grid, two grains of rice are placed on the second grid, four grains of rice are placed on the third grid, and eight grains of rice are placed on the fourth grid. How many grains of rice should be placed on the sixteenth grid?

Grains of rice.”

After Su Jing assigned the last question, she immediately announced the end of get out of class.
