Emperor Ming was dumbfounded. With such a large amount of calculations, there is only so much time to go. It seems a bit difficult.
Su Xiaorui was dozens, and asked with a smile: "Did Grandpa Huang figure it out?"
Emperor Ming rubbed his head: "Are you cheating on Grandpa Huang? How could you do it so fast?"
"I can do it." Seeing that his brother was still thinking about this topic seriously, Su Xiaorui raised his eyebrows slightly and said, "I can also immediately calculate from one to one thousand, and from one to ten thousand."
Emperor Ming raised his brows slightly, wondering if Xiao Rui had memorized the answers to these formulas, and asked, "Then how much is it from 1 to 200?"
Su Xiaorui rolled his eyes and immediately came up with the answer: "Twenty thousand and one hundred."
Emperor Ming didn't believe it, so he immediately sent someone to invite Mr. Wang, who is a master of abacus, to come over.
After Mr. Wang listened to the question, he sat aside and counted quickly, and within a quarter of an hour he reported the answer: "It is indeed twenty thousand and one hundred."
Emperor Ming showed surprise in his eyes, and increased the difficulty: "How much is it from 1 to 136?"
Su Xiaorui's mind turned, and he immediately reported the answer: "Nine thousand three hundred and sixteen."
After a while, Mr. Wang also said the number: "Nine thousand three hundred and sixteen."
Mr. Wang couldn't help wiping off his sweat. He found that he used to have the title of master of abacus, but he was actually not as good as a five-year-old child.
Emperor Ming looked at Su Xiaorui curiously: "How did you do it?"
Su Xiaorui waved his small hand: "Actually, it's nothing. The main thing is that there is a trick. You can make 50 pairs of 100 numbers. 1 plus 100 is 101, 2 plus 99 is 101, and 3 plus 98 is 101..."
Seeing Emperor Ming and Ye Xiaonian's eyes brighten, Su Xiaorui said with a smile: "So there are 50 101s in total."
Ye Xiaonian understood immediately: "So it's five thousand and fifty, and the following questions are all the same."
Mr. Wang looked at the two children in surprise, and exclaimed, "It's really wonderful that you can solve such a difficult problem at such a young age!"
Su Xiaorui smiled and said, "What's so difficult about it? Solving problems requires skill."
Master Wang asked curiously: "50 101s, and 68 137s in the previous few questions, how did you do it so fast?"
"Oh? The multiplication formula." Su Xiaorui rarely had such a good opportunity to perform, so of course he asked people to prepare paper and ink to write out the multiplication formula.
Mr. Wang was stunned. He is usually obsessed with mathematics and often studies these problems.
Now there is actually a child quickly demonstrating in front of him, his face is full of excitement, and he can't wait to take this child home to explore it.
Emperor Ming leaned over curiously, and saw that he was writing quickly. Su Xiaorui explained while writing: "Before doing the multiplication formula, you must memorize the multiplication formula table first, that is, one by one gets one, one two gets two, two two gets four …”
Lord Wang was stunned again, and Emperor Ming was also stunned.
They got it right, looked at the vertical formula again, and thought of the table of multiplication formulas reported by Su Xiaorui, and suddenly found that all the formulas involving multiplication problems became very simple, and they could be obtained directly without an abacus.
Su Xiaorui laughed and said, "My mother taught me these things."
Seeing everyone looking at him with surprised eyes, he became even more proud, and buried his face in Emperor Ming's arms in embarrassment.
The corners of Su Ying's lips curled into a smile, this little radish is really...
It's fine to show off yourself, but also to show off your mother.
Emperor Ming nodded slightly, he always thought that Ying'er was smart, but he didn't expect her to know so many things.
He looked at Su Ying with softer eyes: "Ying'er, you have made a great contribution! You can write down this table of formulas later, if it can be popularized among the people, how much impact will it bring to the lives of the people It's convenient."
"Ying'er obeys!"
Emperor Ming was very satisfied with Su Ying, and immediately rewarded Su Ying with two boxes of South Sea pearls.
When Concubine Mi saw Su Ying thanking her, she was so angry that she died. The two boxes of South Sea pearls were round and big, very precious, and rare treasures. She wanted to make a pair of earrings before, but Emperor Ming didn't let go!
Now two boxes have been given to Su Ying, just because of a messy formula list? !
Emperor Ming saw that the two little radish heads were happy for his mother, and nodded their little noses: "You two are so smart, the emperor also has something to reward you."
Emperor Ming immediately called Eunuch Sun over: "Go and get those two pieces of jade on my bedside."
A flash of surprise flashed in Eunuch Sun's eyes, but he quickly brought the jade over.
Emperor Ming took the jade with his own hands and brought it to the two children.
Seeing the emperor's actions, Concubine Mi's face became even more ugly, if others didn't know the origin of these two pieces of jade, she knew it best.
These two pieces of jade were left by Emperor Ming's grandfather. They are two brave beasts, exquisitely carved, of excellent color, and their value is immeasurable.
Emperor Ming likes it very much on weekdays, and he often wears it with him to play with, but she refuses to take a closer look at him.
Now he handed it over to the two children.
When the Queen Mother saw Emperor Ming giving gifts, she did not give in at all. She said with a smile: "These two children are so smart, and the Ai family will also be rewarded."
The Empress Dowager asked Mammy to bring over a pair of gold locks. The two gold locks were exquisitely crafted and inlaid with huge gemstones, which dazzled the eyes and looked very expensive.
After receiving the presents, the two little buns showed smiles on their faces, and saluted Emperor Ming and the Queen Mother seriously.
When Concubine Mi saw this happy family, she was really going to die of anger, she was rarely so restless as she is now.
At this moment, the queen mother's personal nurse came in and said, "My queen mother, lunch is ready."
Su Xiaorui talked for a long time, and he was also hungry. As soon as he heard that lunch was ready, he blinked at the Queen Mother with a pair of dark eyes.
The Empress Dowager smiled and was helped down, holding a child with one hand: "Come on, Great Grandmother has prepared a lot of food for you today."
The Queen Mother seemed in a good mood, and looked at Su Ying with a three-point smile: "Let's go together."
When Su Xiaorui was led by the queen mother to the middle of the hall, after they sat down, a group of well-trained court ladies began to skillfully set meals.
Soon the dining table was filled with nearly a hundred dishes, including eight-treasure duck, shredded chicken with bird's nest, roast pork... There were even many dishes that he couldn't name. The index finger moved.
Su Xiaorui was almost dumbfounded, he had never seen such a grand occasion before.
After a while, a eunuch knelt on the ground and said, "The meal is arranged neatly, please have a meal."
