"Okay, Guanyin, have you taken the medicine tonight?

You must remember that you must take the medicine on time every day, and when you finish all the medicine, I will take you to Zhaojiazhuang to call the doctor to take a look! ”

"Your Majesty."

On the other side, Li Chengqian returned to the East Palace, changed into his clothes, and began to rest quietly after dinner, waiting for the arrival of the second day.

Inside the study.

"His Royal Highness the Prince."

"The student has seen Taifu."

The Taifu in front of him was the one he saw when he went to Zhaojiazhuang that day.

The speed at which Taifu changed his face made Li Chengqian remember it deeply.

"Your Royal Highness the Prince, after these few days of study, you are finally back.

How have you studied in the past few days, and will you tell the old man about it? ”

Li Chengqian turned into a repeater again, and told what happened that day.

It's just a little different from what the father and queen mother said, and all the unimportant parts are omitted.

I saw that Taifu, nodding while listening!

"Oh, His Royal Highness the Prince, this master deserves to be a master, and what he said is so reasonable."

Li Chengqian said that he was embarrassed again, saying that this master was unruly before, why is this kneeling and licking so much now?

"His Royal Highness the Crown Prince can say hello to that master on behalf of the old man?"

Li Chengqian nodded and replied that you are okay.

When the Taifu heard it, his little face smiled like a flower.

"Alright Prince, let's continue to learn a new lesson today!

Last time, the old man took you to learn the binary equations, and today I will teach you a difficult one. ”

This difficult arithmetic was also learned by myself in the Guozijian and through research and discussion with other masters, and today, it is time to teach it to the prince.

Listen to me, when the arithmetic appeared in front of Li Chengqian, Taifu smiled slightly.

"Prince, I discussed this calculation with the other masters for several days before I came up with the final result.

I have to say that this is a magical discipline for him, in addition to the Four Books and Five Classics, the prince also has to learn these.

At least if the prince becomes His Majesty, the amount of taxes in this world must be counted, and the prince must grasp it, so as not to be deceived by traitorous ministers. ”

The Taifu began to explain the methods they had studied during this period of time to the prince step by step.

Seeing the exercise in front of him, Li Chengqian was stunned at first, and then looked up at Taifu.

I don't know if I should say this sentence to the Taifu, but after thinking about it, I still don't want to save the face of the Taifu.

In the following time, for more than an hour, the Taifu told all the things he had studied.

"Prince, the old man knows that although this question is a bit difficult, you must know that everything is difficult at the beginning, and you don't have to worry.

As long as you can understand half of the topic explained by the old man today, your lesson today will be considered complete! ”

"Tell me, prince, if there is a problem, I will explain it to you personally."

"Well, Master, I was wondering if we could do this to make it easier. Add and subtract these few, so that we can save several steps and work out the answer in less than an hour.

Isn't this a calculation simpler than what you just said? ”

What?

After hearing this, the Taifu quickly stepped forward and calculated according to what the prince said, until the result was finally calculated.

The final result turned out to be exactly the same as the result of his calculation, but the method of calculation was several times simpler than the method they had studied.

Seeing everything in front of him, the Taifu smiled awkwardly.

"Too, His Royal Highness the Prince, how did you solve this arithmetic problem, and can you solve the old man's puzzles?"

"Taifu, in fact, this arithmetic problem was also learned by Uncle Zhao.

I thought this arithmetic problem was very interesting, so I wrote it down, but today it is the same as what Taifu taught. ”

The Taifu was stunned for a moment, and then relieved.

He knew the master's ability, although the two had not met, but in terms of thought, they had communicated more than once.

Looking at it today, the gap between myself and others is not a little bit worse!

"It's okay prince, since you have already studied this, we can also learn others!"

As he spoke, he brought out another arithmetic problem, but this time, this Taifu also became smart, and did not explain it immediately, but took the lead in asking, has the prince studied this question with that master?

Li Chengqian looked at it, glanced at this familiar exercise, and nodded!

"Taifu, then I have also studied this question."

"Is there an easier way to solve the problem?"

"Taifu, this problem is so solved!"

Seeing the prince sitting on the side, he began to solve this problem step by step.

The lady's eyes widened, and he quickly took the paper and looked at it from beginning to end.

While looking at it, I sighed, wonderful, wonderful, I didn't expect that after studying for so many days, it would take more than half an hour for me and a few masters from Guozijian to solve the exercises, and the other way to solve them so quickly?

"That prince, there are still a few questions here, take a look!"

The Taifu simply listed all the remaining questions, which were originally intended to be the amount of tasks for the prince this month.

Of course, the original plan was that the prince would already be good in a month.

Now it seems that the previous idea was a bit wrong.

Li Chengqian answered these arithmetic questions in turn, and looked at the Taifu who was stunned.

"His Royal Highness the Prince, the old man didn't understand this place, please slow down!"

"It's Taifu."

The morning passed quickly, and it was obvious that in the study of the prince's mansion, Li Chengqian and the prince had changed their identities.

The Taifu listened attentively, and Li Chengqian said everything he knew.

From time to time, the lady would stop to ask.

"His Royal Highness the Crown Prince, why is this question answered like this?"

"Taifu, don't worry, this title is written like this."

Fortunately, they are very knowledgeable, and with just a little bit, everything will naturally fit in.

While doing the question, before I knew it, it was noon.

It's already time to eat at noon, and in this study, the Taifu and His Royal Highness the Crown Prince have no intention of eating.

The servants who were waiting outside the study secretly thought to themselves that by this time period, the prince and they should have come out long ago.

Could it be that this Taifu and His Royal Highness the Crown Prince are still studying?
