The crowd gathered around.

Li Yuanying said: "This is the means in arithmetic, wait and see, here are several conditions, five days, six days..."

——Aye, it's snowing in Chang'an.

The handwriting is immature, and it is a letter written in circles.

Since last year, Doudou likes to act as a document for his family, for example, what to write, or what to record, come to me!

——Ah Fu is my favourite. When it snows outside, he runs out and can't hold back.

Pandas in the Qinling Mountains are not cute. They hunt for food in the ice and snow in winter.

——The eldest brother is getting more and more rigid. He does his homework every day when he comes back from his degree, and he doesn't play with me after dinner, saying that he has to think about some homework.

Jia Pingan was a little helpless.

He has been instilling in the boss that you are the eldest son of the family, what you need to know about the eldest son...

Later, he found that he had instilled too much, so he stopped.

But the boss still couldn't help walking on the road of the boss.

Childishness is gone.

Study hard every day.

You have to teach your younger siblings.

You have to care about your parents.

In another ten years, it is estimated that he will still have to take care of everything in the family, including property.

Am I... over?

Jia Pingan was lost in thought.

"Look, list out the conditions, and as soon as the equation is solved, the result will come out, either today or tomorrow."

Li Yuanying felt that he was a god.

A group of people looked at him in awe, but immediately turned to Jia Pingan who was thinking.

"It turns out that the new learning can really be used in battle."

Han Yuanliang said: "The two armies are attacking, and the opponent's itinerary can be calculated by doing calculations..."

Li Yuanying said: "It's not just that."

"What else?"

Several generals are thirsty for knowledge.

Li Yuanying really wanted to pretend to be tough, but...

"The king doesn't know either."

Everyone looked at Jia Pingan.

The firstborn is the firstborn!

Jia Pingan figured it out.

Just like Yang Deli, after being taken to Jia's house, he knew what his mission was.

My aunt would say, "Deli, go and see where is Ping An?"

"Deli, don't let Ping An play by the well."

"Deli..."

Jia Ping'an could imagine his cousin's attitude towards the original body back then.

This is life!

Many people in later generations want to seek relief, what family, what...

But this is life!

The eldest is the eldest son, and his destiny is to study hard and do things hard, and when he goes out, he represents the face of the Jia family...

Jia Pingan figured out the problem, raised his eyes and saw everyone looking at him, he smiled and said, "Is there something wrong?"

Everyone looked at Li Yuanying.

Li Yuanying said: "Sir, they want to ask for some advice on how to apply the new knowledge in battle."

"That's it!"

Jia Pingan thought for a while, "For example, if the two armies are facing each other, how many people are on the enemy's left wing, and how long will it take to attack and reach our army's formation... Then how many people are on our right wing? How long will it take to send reinforcements to the front line of the right wing..."

Very simple!

Everyone thinks it's okay.

Han Yuanliang said: "Duke, these things are all experience."

Jia Pingan smiled, "You are estimating. The new learning is different, it is calculation. This distance can be calculated directly. When the enemy troops dispatch the left wing, the result can be calculated in a few breaths. If the reinforcements arrive late, you Two orders should be issued, one ordering reinforcements in the center, and the other ordering the right wing to resist desperately..."

Han Yuanliang understood, "How long?"

Jia Pingan nodded, then got up and went out.

It's time to camp.

Li Yuanying murmured: "Mr. said a few breaths to save face for you!"

Han Yuanliang asked, "Why?"

Li Yuanying said: "Students who are good at mental arithmetic in mathematics can get results in an instant for such simple problems."

Han Yuanliang was silent.

Yang Caihong asked: "Maybe I can learn later?"

Li Yuanying shook his head, "I don't know."

He caught up with Jia Pingan.
