Personally gifted Hana Goka with utensils, and Yilan returned to the podium and calmed down, "Princes, welcome here, let's explore the mystery of numbers together. Numbers contain endless fun, worthy of our play, excavation, he can enlighten our wisdom, create endless possibilities. The crisp voice, the confident smiling face, and the opening statement that was different from the previous ones made everyone feel shocked, "First of all, let's do a warm-up game." ”

Yilan took out the abacus, which everyone had on the table, and they had already been notified to bring it.

"First of all, the addition of 20 single digits, I will report the number, you can do mental arithmetic, you can also use the abacus to assist." Yilan smiled and said slowly, "5 plus 4 plus 9......"

I don't know if it's easier to do one-digit mental arithmetic or if everyone is not used to this kind of teaching method, although Yilan is reporting numbers, but the abacus below is sparse and there are not a few clicks.

In a blink of an eye, the 20 numbers were reported, "Can anyone tell me how many of these 20 numbers add up?" ”

Silent.

Yilan's is called collapse, teaching needs to be interactive, and singing and harmony have taste. Forced to calm down, still looking at everyone with a smile, from time to time he glanced at Xiao Wu, who was sitting in the front, and Hua Wulone, who was standing behind the most cowardly, but it was a pity that he both stared down at the paper and didn't look up.

"I'm coming, it's one hundred and nineteen." The Emperor replied in a loud voice, "If there is a question, I will come too." "I took an abacus in my hand.

"Long live Xie, it's 119" Yilan smiled and bowed slightly, "The next one to increase the difficulty is the addition of two digits, which is also 20 numbers, and the speed at which I report the numbers will be accelerated, I hope you are ready." ”

With the first warm-up, the second question was obviously enthusiastic, just reported two numbers, the sound of the abacus at the bottom rang out, Yilan walked to the middle of the table, as much as possible to raise the voice, so that everyone could hear clearly.

When the last digit ends, "1058."

“1056”

“1158”

All sorts of answers flew out at once, "It's 1156." Hua Wushan didn't have an abacus, just stood there and replied with a smile.

"Lord Xie Liu, it's indeed 1156." Ylang reported the final answer. In the blink of an eye, I saw Hua Wuxiang with a bitter face, and the numbers on his abacus were far from the correct answer.

"I've prepared a third set of questions, I don't know if the princes want to try again." Yilan asked with a smile.

"Yes, again." The boys' competitive nature was immediately stimulated, and they were eager to try the third set of questions, striving for the fastest and most correct ones.

"The third set of questions is more difficult, it is the addition and subtraction of three-digit numbers, there is addition and subtraction, everyone must listen clearly." With the sound of numbers, there was a sound of abacus at the bottom, but after 10 or so numbers, many young children stopped calculus, and only a few older ones were still insisting.

"Plus 216, it's over." As Yilan's crisp voice stopped, the sound of the abacus stopped, but no one came out to report the numbers.

"Huh? Isn't it good yet? Ylan said curiously.

"Is it 8827?" A voice sounded, not so confident.

"No, it's 6238." Rebuttal.

"I figured it out to be 5721."

"It should be more than 6,000, but I seem to have missed 2 numbers."

"It's 6124." Hua Wu said slowly.

"I calculated it was 6324." The emperor raised his head from the abacus and gave a different answer.

Everyone was staring at Ylang.

"The paper of this question will be sent to you, and you can go back and calculate it." Yilan Yanran said with a smile, "If you don't calculate it correctly today, you don't need to be angry, quick calculations need to be practiced, and through a period of practice, everyone's level will make a big leap." ”

"Let's explore two mathematical concepts, perimeter and area." After a pause, Ylang said the topic of today's lecture. Next, the algorithm of the circumference and area of the square, rectangle, circle, and triangle was analyzed in simple terms, and it took a full hour. Yilan took a charcoal pen and wrote and drew quickly on the wooden board covered with white paper, there were formulas and cases, and the white paper turned back page by page, and there was a thick stack. At the end, there is a very complex calculation problem, and you need to add a few auxiliary lines to calculate the required answer.

These contents are indeed a bit much, plus the previous quick calculation exercises, there is a small time of one and a half hours, the older ones are listening to the calculations, while recording, the younger ones are almost unable to sit still after the most lucrative, but because the emperor and their respective fathers are there, they dare not move at will, and the content of the lecture is obviously not digestible.

"That's the end of today's content, I hope it will be helpful to you, and I will explain the answer to the last question in the next class. Today's content is a bit much, if you have no mastery, please feel free to come to me to discuss, the last, thank you for your participation. After speaking, he bowed to everyone.

No one has experienced such a course, obviously everyone is not familiar with the process of Yilan, although the course has been announced to be over, and they have bowed to the end, but everyone sitting here has long been accustomed to others saluting them, so most of them don't care, a few people stood up, and more were stunned.

"What are you doing, I didn't see your master saluting you." The emperor was the first to stand up.

Only then did I remember that there were the emperor and their respective fathers who were listening to the class, and they all stood up straight in a hurry, still singing a big promise to Yilan.

"Ylang has worked hard, are you tired?" The emperor walked up to Yilan, his eyes full of appreciation and care. "You rest first, and then go to my study with Wu Lian, I want to set up a banquet for Young Master Qiu." After speaking, he laughed with several princes.

"Don't be tired, Your Majesty, what you said today is okay, the first time you give a lecture, it is inevitable that there will be mistakes and omissions, and I hope that the emperor and the princes will correct me." showed a smiling face, but his eyes glanced at Hua Wulone.

Seeing Yilan looking at herself, Hua Wulan was full of sweetness, and subconsciously wanted to go to Yilan's hand, but when she touched it, she avoided it, realizing that there were children and subordinates next to her, Hua Wulan also blushed slightly.

"Yes, that's a good point." When the emperor saw it, his smile deepened, "Rest first, and wait for my study." ”

"Yes." Ylang crouched down and saluted.

The emperor took a few adult princes to take the first step, and the children naturally knelt on the ground to send them off.

Yilan followed Hua Wulin together, and the teaching aids were cleaned up by Lichun and them.

There is a long way to go from the place where the prince is studying to the emperor's study, Yilan holds the stove in his hand, and the two walk side by side, and from time to time there will be eunuchs and palace maids who are working on the side of the road.

Not long after leaving, Yilan stopped and looked at Hua Wulone's eyes full of admiration.

"What's wrong?"

"Only you are right about the three quick calculations, how did you do it without the help of an abacus?"

Hua Wushan smiled, with endless tenderness in his eyes, "How did you come up with this?" ”

"That's what my teacher taught me when I was studying." Ylan's mind was far, far away.

"Oh? Is it? Hua Wushan was curious, but it could be seen that Yilan didn't want to answer, so he didn't ask any more, but just grabbed her shoulder and let her lean on her shoulder.

Stepping into the study, a large long table was already covered with wine and food. Yilan was really hungry, and since she got up before dawn, it has been three minutes now, and she has only eaten two small pieces of snacks, and she has not even drunk a sip of water.

Naturally, he wanted to give the emperor a salute first, but before he could get down, he was supported by Hua Wulone, "Okay, Yilan, you are already tired, my father will not blame you, sit down and drink some water first, you are hungry." As he spoke, he pressed Yilan onto the chair and took a cup of tea and stuffed it into Yilan's hand. Only then did he kowtow to the emperor and say goodbye.

"The sixth brother is really in love." This kind of words with a mocking tone naturally came from the mouth of the seventh master.

"Alright, let's all sit down and eat." The emperor is very kind today. "Yilan, this is all light, you eat more, and I personally sandwiched some into Yilan's bowl."

"Your Majesty." Yilan was a little embarrassed, and then he found that he was sitting on the left hand side of the emperor, and Hua Wushan fell down. Sitting opposite sat the third master, the seventh master and the twelfth master.

"Hehe, it's convenient for the sixth child to take care of you by sitting like this. Sixth, I gave Yilan more of her favorite food, and went to Fancheng, how can I look thinner than before. The emperor's face was full of love.

The ancients paid attention to food and silence, and the emperor and Hua Wulin kept adding vegetables to Yilan's plate, and the plate was always full. It wasn't until he saw that Yilan had indeed eaten a lot that the emperor put down the dishes and chopsticks.

Hua Wuxiang pouted beside her, "Father is really partial, so he is good to Sister Yiyi." "Hana Goka was an outlier among the princes, and the emperor was very fond of him, and he always bowed to him, without having to follow the rules of other princes, and he acted very boldly. But his brothers were very tolerant of him, and they did not see any wariness among other brothers.

"How can a father be partial? Why is it bad for you? "The emperor always dotes on Hana Goka.

"If you want to change the sixth brother's other daughter-in-law, which one is not standing by and serving." He didn't open any pot to mention which pot, and the flower glared at him.

Just as everyone was sitting aside to drink tea, Xiao Wu, the son of the third master, walked in and saluted everyone one by one.

"Xiao Wu, why don't you give your sixth aunt a salute. Have you all heard what your sixth aunt told you today? The third master said on the side.

Yilan looked up at Hua Wuchen suddenly, and then looked at the emperor, until Xiao Wu kowtowed and called the sixth aunt to stand up, and the emperor had no intention of objecting.

"The little Wu that Aunt Sixth talked about today understands it, but the last problem has not been solved." He said.

Everyone looked at Hua Wuxiang, although the two were uncles and nephews, but the age difference was one year old, "The most difficult question was calculated in class, and the area of that small piece was 26." He looked at Xiao Wu proudly.

"Xiao Wu, how much did you calculate?" Ylan looked at him.

"I calculated that it was 26, but it didn't feel right." He was a little squirming.
