Everyone was silent for a long time, some people saw the military newspaper and thought, and some made eye contact with each other.

After a while, the eldest grandson Wuji said first: "The minister thinks that we should wait and see how the situation changes. ”

Wei Chigong said: "The last general thought that he should send troops to continue to the border pass and continue to threaten Tuyuhun. ”

Fang Xuanling also said: "Your Majesty, the minister thought that he wanted to make Tuyuhun feel that he could only continue to fight with Tubo, not only to continue to send troops, but also to let Tuyuhun know the consequences of attacking the Tang Border Pass. ”

Fang Xuanling's words, everyone understood the taste.

At this time, Datang not only had to watch from the wall, but also continued to arch the fire, so that Tuyuhun and Tubo fought more fiercely.

Under the operation of Li Shimin's think tank, Li Shimin wrote another letter and sent it to Tuyuhun, which was to hold Tuyuhun accountable for attacking and disturbing the Tang Border Pass.

This will is for the king of Tuyuhun.

In order to let the king of Tuyuhun understand that the Tang Dynasty will attack Tuyuhun at any time. , as long as you admit your mistakes and apologize for your sins and apologize, Datang will not participate in the war between Tubo and Tuyuhun, you can fight with confidence and have a good time.

And Datang also secretly continued to arch the fire on both sides.

Li Shimin is righteous on the face, and he is still the beloved Tian Khan who hopes that the world will be peaceful.

And behind the scenes, a lot of fine work was dispatched, and they continued to make small moves between Tuyuhun and Tubo, so that they could fight more heartily.

Engaged in pre-co-ordination to multi-handed arrangement, and then to the aftermath of the current finish.

The current political affairs of the Tang Dynasty are still clear, and the officials are also capable.

An alley in the eastern city of Chang'an.

The decoration of the home is gradually coming to an end, Li Yue is busy in the house, she takes out Zhang Yang's futon and scrubs it carefully.

After washing, put it in the yard to dry.

The sun is shining, and it is very comfortable to slop on.

The exterior of the house has been almost renovated, and the old house has now been renovated.

When you look up, you can see a sturdy roof, giving you a sense of relief.

Zhang Yang was still busy in the house, tearing down a few useless walls and repainting the interior of the house.

Li Yue felt that the room was also much more spacious.

After cleaning the yard, Li Yue saw the abacus in Zhang Yang's room when he had nothing to do.

This abacus is very large, much bigger than the small abacus chips outside.

There are also a lot of beads.

Zhang Yang looked at Li Yue fiddling with the abacus and said, "Will you use this?" ”

Li Yue held a volume of account books, and after flicking the abacus with his fingers for a while, he said, "I understand, there are more than 1,500 in total." ”

Zhang Yang himself did the math and found that it was really this number.

This is the entire property of his own family, one thousand five hundred and six.

Now he is buried in the ground by Li Yue.

Zhang Yang was puzzled: "I haven't seen you use this before." ”

Li Yue smiled a little proudly, "In fact, there was a master of mathematics in the Han Dynasty, Xu Yue, who wrote a book of "Mathematical Calculations", which recorded many kinds of algorithms. ”

Sometimes those who study the wisdom of the ancients will feel very surprised and amazed at the wisdom of the ancients.

Zhang Yang listed another four operations, "You calculate this." ”

Li Yue's small face looked at the topic, and he turned the abacus for a while and frowned.

I took a pen and recorded it, and it took a lot of time to figure it out.

Zhang Yang looked at her and calculated the answer was right.

"Actually, there are some more convenient solutions."

"Really?"

Li Yue blinked and said excitedly, "Tell me about it." ”

I don't know why the little daughter-in-law is so interested in mathematics.

Zhang Yang said: "In fact, multiplication, division, addition and subtraction have priority, if there is no priority, then calculate from left to right, and addition and multiplication also have a digital progressive relationship......

In order to learn more efficiently, Zhang Yang taught Li Yue how to write Arabic numerals by the way.

Zhang Yang said to her: "Maybe we are the only ones in this world who can understand these symbols." ”

Li Yue looked at the Arabic numerals from zero to nine, as well as the symbols of addition, subtraction, multiplication and division, and nodded vigorously.

patiently talked to Li Yue about mathematics, and this little girl listened very carefully.

In an hour's work, Li Yue has mastered four operations, and even learned the vertical style.

It may be that Li Yue had a certain foundation when he was a child.

I can't say that my daughter-in-law is a once-in-a-century mathematical wizard.

Zhang Yang said: "I will teach you more complex quadratic equations and geometric operations tomorrow. ”

I thought that this would always be a stump.

Why is the little daughter-in-law more excited in her eyes?

In the following days, Zhang Yang not only usually decorated the house, but also taught Li Yue mathematics.

It turns out that Li Yue does have a certain talent in mathematics.

After half a month of teaching, Li Yue has been able to do more complex geometric application problems.

She was like a sponge, frantically absorbing math knowledge.

Li Yue likes to listen to Zhang Yang's lectures very much, which makes her feel that the distance between herself and Zhang Yang is getting closer a little bit.

If you can learn more knowledge, maybe you and Zhang Yang will get closer and closer, don't husbands and wives understand each other like this?

So much so that two huge wooden planks hung on the wall of the yard of the house.

Zhang Yang wrote the question on one wooden board, and Li Yue answered on the other.

Looking at the answer calculated by Li Yue, Zhang Yang was secretly shocked in her heart, she could grasp the substitution of X, Y, and Z so quickly.

Her comprehension ability is comparable to others in this era, and this comprehension ability is simply beyond the sky.

In the past few days, Li Yue has gained an unprecedented sense of harvest.

Every day, I feel that I have learned something newer, and as I learn more, I feel closer to Zhang Yang.

"What are we going to learn tomorrow?" Li Yue stood in the sunset and said.

"Tomorrow we will change subjects, tomorrow we will study science."

"What is science?"

"Science and mathematics are very close, and it is also a discipline that cannot be separated from mathematics."

"Okay, we'll study science tomorrow."

The boards are full of formulas that others can't understand.

From various geometric symbols to multiplication and division of numbers, if someone else sees this board, they may think that it is some meaningless scribble.

This is a text that only Zhang Yang and I can understand.

Li Yue looked at his formula with a sweet smile on his face.

At night, Zhang Yang tossed and turned in his bed and couldn't sleep, because he found a major problem, my daughter-in-law was a top student.

In addition to going to the post house every day to share the money with him, Zhang Yang has always been teaching Li Yue at home when he goes to the street to buy vegetables.

Looking at the symbols written by Zhang Yang on the wooden board, Li Yue wondered, "What do these symbols mean?" ”

Zhang Yang said to her: "These words are actually a kind of language, and putting these letters together is the pronunciation of that language." ”

Under Li Yue's gaze, Zhang Yang said something.

Listening to this kind of language that he had never heard before, Li Yue felt and said: "This language is so good, it sounds clear and sonorous. ”
