I am the cook, but I am Li Er's son-in-law

Yin Lulu admired this group of scholars.

In her eyes, scholars are a group of very powerful people.

The kind that can capture the moon in the nine heavens and catch turtles in the five oceans.Usually at their receptions, they would talk about "dig the middle hall and make it a garden, plant sugarcane in the front yard", "picking chrysanthemums under the eastern fence, and see Nanshan leisurely" and other words that she didn't quite understand.

But when it comes to arithmetic, Yin Lulu has been following Yin Xuan to learn these things during this time.

Yin Xuan himself has double majored in a degree in mathematics, so he has some experience in arithmetic, plus Yin Lulu is very talented, physics and mathematics are like braised pork and rice, they complement each other.

The progress is not slow.

In terms of functions, I have already started to learn binary linear equations. In terms of geometry, I also understand the calculation formulas of basic graphics.

Yin Xuan's grasp of basic arithmetic ability is particularly important - he has suffered too much in this regard.

Even now, Yin Lulu has to do a hundred arithmetic problems of addition, subtraction, multiplication and division every day.

In Yin Lulu's eyes, the questions asked by the orderer were not too difficult, and it even gave her a feeling that she could do it herself.

Yin Lulu trotted over, and before the officer's third question came out, she said timidly, "Uncles, can you bring me one?"

They are no strangers to Yin Lulu, she is the cute and lovely younger sister of the store owner.

Speaking of which, when they came here a few times before, they made a joke and mistook Yin Lulu for Yin Xuan and Li Lizhi or Li Shu's daughter.

They felt that they couldn't blame themselves for this incident. Isn't it a matter of course that a good-looking husband and a good-looking lady gave birth to a daughter carved in powder and jade?

Wu Youdao smiled and nodded: "The little girl also learned to count?"

Yin Lulu nodded, glanced at the fried skewers on the table from time to time: "Yeah, my brother taught me some things."

The reason why she wanted to join in was not because she was interested in mathematics, but because she was interested in fried skewers.

The fried skewers are delicious, but Yin Xuan never let her eat more.

The food at home is not bad, and there is no shortage of calories from fried skewers.

Yin Lulu is still young, so she shouldn't eat too much, she is prone to indigestion, and it is easy to grow into a small fat ball - although Yin Xuan is happy to see Yin Lulu gain weight, she doesn't want to see Yin Lulu chubby.

It's not that being fat doesn't look good, it's because being fat is unhealthy.Not to mention the three highs, fatty liver, cardiovascular, and diabetes are all prone to fat people, and girls are more likely to suffer from some gynecological diseases.

Being healthy is not the same as being fat.

Yin Lulu can only eat once every seven days, and the amount of food in her mouth is not much each time.

But it made her hungry.

Wu Youdao didn't know Yin Lulu's careful thoughts, so he nodded and agreed: "Since the young lady is interested, let's come together."

"But you are still young, you can't drink wine, so how about it, if the little lady can't answer, how about a glass of water?"

Yin Lulu has no objection.

Other scholars have no objection to this, who can refuse a cute and studious little girl?

Yin Lulu sat behind the fifth person and ranked sixth.

The ordering officer read out the third question: "Several people bought one item today. Each person paid [-] qian, and there was a surplus of [-] qian. Each person paid [-] qian, which was less than [-] qian. Ask the number of people and the price of the item."

It's a question of equations.

Yin Lulu quickly made a judgment with her small head.

Within ten breaths, the fifth person did not answer.

After the man was fined with alcohol, everyone looked at Yin Lulu expectantly.

With a small face, Yin Lulu said the answer softly: "There are four people in total, and the price is 31 renminbi."

The table was full of surprises.

It turned out to be right!

Yin Lulu was overjoyed, stood up, tiptoed hard, and grabbed a bunch of fried eggplants.

The drinking order continued, but the people at the table couldn't help but look at Yin Lulu a few more times. The question just now wasn't too difficult, and they could do it.

It was just calculated in such a short period of time, especially since Yin Lulu was still so young, it surprised them.

It was a quick turn around.

When it came to Yin Lulu again, it was only the sixth question.

The commander looked at Yin Lulu who was eager to try, paused, thought for a while, and asked a question with the intention of taking a school exam: "Today, there are 570 six steps, what is the square geometry?"

Yin Lulu replied almost without thinking: "24."

The table was full of people looking sideways.

so fast?

Some people dipped their fingers in the wine, calculated, and when the results came out, they looked at Yin Lulu with somewhat complicated eyes, full of surprise and sigh.

This little girl calculated the prescribing so fast?

Yin Lulu had already grabbed another bunch of small meat skewers, and gnawed them happily.

She finally realized the joy of learning. Prescribing squares and squares are things her brother has always asked her to memorize. Now she has memorized the square of 31.

The drinking order continues.

When she turned to Yin Lulu again, she was left with a question that neither of them could answer after taking the exam: "There is only one foot in the pool, and reeds grow in the middle of the pool, one foot above the water surface. If the reed is pulled toward the shore in a direction perpendicular to the water surface, the top of the reed will just touch the shore."

"Excuse me, the depth of the water and the length of the reed."

This is a geometry problem, and the test is the Pythagorean theorem.

Yin Lulu dipped in the water and drew back and forth on the table. The whole table wanted to see if Yin Lulu could solve this problem, and the time was not as strict as other people's requirements.

After ten breaths, no one made a sound.

After another ten breaths, Yin Lulu frowned a little.

She raised her head and gave the answer: "I figured it out, the water is twelve feet deep, and the reeds are thirteen feet long."

Some people didn't even have an idea, couldn't do the calculations, and looked at the commander in amazement.

The commander nodded, indicating that Yin Lulu's answer was correct.

This made the mood of the scholars at the table even more complicated. Many people started to calculate with Yin Lulu, but before they could give an answer, Yin Lulu answered.

They can also find a reason for prescribing, such as what, they have memorized it in advance.

But this topic.
You can't memorize it in advance, can you?

This time Yin Lulu didn't reach out to get the fried skewers, even though she was very hungry, she still sat obediently.

"Little girl, why don't you bring food?" Wu Youdao asked with concern, while talking, he also made a gesture to give Yin Lulu a bunch.

Yin Lulu shook her head quickly, picked up the water cup and drank it: "If I didn't make it in ten breaths, I failed. My brother said that when playing a game, you must abide by the rules of a game."

The people at the table were even more surprised.

Someone looked into the kitchen.

Originally, they just admired the craftsmanship of this restaurant, but after all, it is a restaurant chef, but now it seems that this family is not just a simple cook.

As far as Yin Lulu's abilities and morals are concerned, they cannot be taught by an ordinary family.
