"What about 25 times 720 minus 65?" a voice sounded behind Merton.
"Seventeen thousand nine hundred and thirty-five." Merton answered subconsciously, but suddenly realized how Lizhi's voice was changed into that of an adult, and the problem was too difficult for a seven-year-old child!
Merton subconsciously looked back and found that Li Shimin appeared behind Merton with a black face.
Merton couldn't help but have a sudden in his heart. This time, the great demon king really came.
"See you, your majesty!" Morton, with a faint heart, quickly turned back and bowed.
"See your father!" Li Zhi's small face was pale with fear. For him, what he was most afraid of was Li Shimin, and it happened that Li Shimin caught him cheating Merton to help him with his homework.
Li Shimin's face was gloomy and he was about to get angry.
Li Zhi's liver trembled carefully. He couldn't help but turn his eyes to his last magic weapon, Princess Jinyang.
"Father!"
The soft voice of Jinyang rang out and sprang at Li Shimin.
"Hahaha! How did you sneak out again, Naoko!" Li Er, like an old student of Sichuan Opera, immediately changed from a black face to a smiling face and picked up the princess Jinyang who jumped into her arms.
"Nine elder brothers said to take Yuzi to see the great demon king! He said that after Yuzi entered school, he would know how terrible the great demon king is?" said Princess Jinyang in a delicate voice.
Li Zhi suddenly turned pale. He was completely betrayed.
"The great demon king?" Li Er looked at Merton contemptuously, as if to say that he could be called the great demon king, just like a small catfish.
"Your Highness king of Jin is joking!" Merton said with a dry smile.
"Yes! Yes! The child is joking!" Li Zhi giggled and nodded.
When Li Er arrived, all the princes quickly got the news and immediately poured out.
"See your father!" the princes said together under the leadership of Li Chengqian.
Li Chengqian took the lead. Li Zhi, who was the last to enter school, ranked last, and nine princes stood neatly.
Merton looked at the nine princes arranged in high and low from the back, not including the swaddling princes in the harem. Merton couldn't help smacking his tongue and admired Li Er's stallion attribute. If he was in an ordinary family, he couldn't afford it at all!
Li Chengqian looked at Merton and couldn't help blinking and nodding slightly. Other princes also turned their curious eyes to the strange boy.
Merton showed his signature smile, hugged his fist and saluted: "Merton in Mojia village, see you princes!"
"Merton!"
The rest of the princes could not help but fret. The little fat man behind Li Chengqian showed an excited look, while the princes behind him showed a look of resentment one by one, including Li Zhi.
In Li Zhi's short school experience, he originally thought that endorsement was the most painful thing, but since Li Chengqian learned arithmetic from outside, Li Zhi found that endorsement could not continue to recite, but if he couldn't learn arithmetic, he couldn't scratch his scalp!
In his mind, it was not the demon king or something that could come up with such a abnormal problem.
Chongwen Museum.
Li Shimin was sitting upright. Next to him, an old man with gray hair sat down and was looking at himself with interest. Merton nodded and smiled at him as a greeting.
The old man was stunned. He didn't expect to get Merton's response. He also smiled and nodded.
"Wei Aiqing! How is your prince's academic progress?" Li Shimin asked the nearby.
Merton looked very active. His surname was Wei. He could sit down in front of Li Shimin again. There was only one person who had such treatment - Wei Zheng.
"Under avoidance, the schoolwork of the princes is progressing very smoothly. Even the youngest nine princes have recited thousands of words skillfully." Wei Zheng replied with an arched hand.
"Oh! What about arithmetic?" Li Shimin asked.
Wei Zheng smiled bitterly and said, "tell your majesty that the new arithmetic is easy to learn but difficult to master. All princes are still groping. I think it will improve in time."
In fact, Wei Zheng has said this in a round way. Except for Li Chengqian, who was personally taught by Merton, Li Tai, the king of Wei, who is very talented and smart, learned the best. Other princes can be said to be a mess, especially Li you, the king of Qi, who is making trouble. It's nonsense.
"Easy to learn but hard to master?" Li Shimin said with a flash. "I saw Merton outside Chongwen hall just now, but he opened his mouth to arithmetic. Can't Merton try?"
When Merton heard the speech, he immediately felt that he was wronged like Dou E. your own son didn't learn. He even said that I didn't hide and teach.
"Oh! Mo xianbo has such a unique skill?" Wei Zheng was surprised.
"If you go back to the Duke of Zheng, it's not a boy hiding private things. This is the method of lightning mental arithmetic. You need to learn arithmetic for a period of time before you can start practicing."
"Lightning mental arithmetic? Mohism has such a unique skill!" Wei Zheng said with a look.
"Go back to my father! I also want to see Mo xianbo's mental arithmetic. I wonder if I can ask Mo xianbo to demonstrate it." little fat Li Tai said excitedly.
Wei Zheng said with a moving look, "if only the nine princes could write questions in turn and let Mo xianbo answer!"
"You don't always complain that arithmetic is too difficult. Now there is an opportunity in front of you. Let Merton answer the most difficult questions and see if they are too difficult or you haven't learned them well!" Li Shimin said in a deep voice.
"Yes!"
All the princes could not help showing an excited look, and all were eager to try.
So before Merton opened his mouth, a competition was so happily decided.
Li Er looked at a group of princes who were excited to give questions. A smile appeared at the corners of his mouth. He turned to the listless Merton and said, "Merton, if you answer wrong, we'll calculate your recent account."
Li Shimin showed Mori's white teeth and threatened.
Merton immediately fought a cold war and quickly cheered up. He couldn't even cope with it. The problem of offending the prince should be solved in the future! At present, we still pass Li Shimin first.
Soon all the princes finished the topic and looked at Merton eagerly.
Li Zhi took the lead in solving the problem. Unfortunately, his level of arithmetic is limited, and his knowledge is within the hundred digits. Although he has made every effort to work out the mixed addition and subtraction of five numbers, Merton still opened his mouth and gave his answer at the first moment when Li Zhi finished reading the problem.
"That's right!" Wei Zheng said with a nod.
"Hey!"
Accompanied by Li Zhi's disappointment.
The other princes showed extremely interested eyes, which was so simple in such a troublesome calculation.
Lightning mental arithmetic is really not simple.
Then, although the other princes racked their brains to make a question, they still did not bring the slightest trouble to Merton.
Soon, Li Ke, the Third Prince of Wu, was also defeated. His topic was the mixed operation of multi digit addition, subtraction, multiplication and division, and gave ten numbers at once.
"Three hundred twenty-four!"
Merton gave the answer at three breath time.
"Wow!"
The princes could not help crying out.
You can't even finish writing questions in three interest time! And the mojiazi has written out the answer.
"It's so fast!" Wei Zheng was shocked to see that he had just set aside three figures.
This time, even Li Shimin's eyes were full of brilliance.
"Mo County Bo's mathematics is really unique, and Xiao Wang admires it!" said Li Ke, king of Wu in admiration.
"Your Highness the king of Wu is very kind. I'm just taking advantage of the calculation!" Merton hurriedly said modestly.
He was also deeply interested in the tragic prince. Li Ke, king of Wu, had the royal blood of Sui and Tang Dynasties. He was the most noble blood in the world, but that was also his deepest original sin. Finally, he died unjustly.
"Xiao Wang and Li Tai have met Mo County uncle!" said the fat man Li Tai politely.
"I've seen your Highness the king of Wei!" Merton dare not underestimate this famous figure in history. According to historical records, Li Tai, the king of Wei, is a standard Xueba!
He was born well and worked hard. He almost abused all the princes. No wonder he was deeply loved by Li Shimin and even threatened Li Chengqian's position as Prince for a time.
"This time, the Green Finch is interested!"
When Li Shimin saw Li Tai's expression, he knew that Li Tai must be holding a big move.
Sure enough, Li Tai started his topic, and the whole audience was in an uproar. His topic had only two numbers, two super long numbers divided by each other.
"One five eight seven six five nine three seven one eight two divided by six one eight four nine five."
"Wow!"
There was an uproar. How can such a long number count.
All the princes adore Li Tai. It's still the second brother. Let's see how the Mexican family calculates it.
Wei Zheng looked around at the calculation chip in his hand and didn't know how to start. Li Shimin also looked at Merton with great interest and wanted to see a little panic in Merton's eyes.
"Two five six six nine six nine." after only five minutes, Merton suddenly looked up and gave the answer.
"Wow!"
"How is that possible?"
"How can you work out the answer so quickly!"
………………
Everyone was in an uproar. Li Shimin stood up and looked at Merton in disbelief.
"Second brother, is Merton's answer correct?" asked King Wu Li Ke incredulously.
Li Tai twitched his face and said, "if I say I made up a question casually, I don't know the answer myself, do you believe it?"
Finally, after a quarter of an hour of calculation, Li Chengqian and Li Tai finally calculated the super long problem.
"The answer is correct!" Li Chengqian looked at the answer in his hand and breathed heavily.
Suddenly, everyone was boiling. Everyone looked at Merton strangely. Such a large number was calculated in a short time. Lightning mental calculation was God.
Merton smiled in his heart, what is this? You didn't see some radio competitions in future generations. Those topics are really abnormal, and how warm the atmosphere is.
Merton lost eight princes in a row, leaving Prince Li Chengqian.
Li Chengqian looked at the title in his hand, sighed and said, "all the arithmetic knowledge in this palace is received by Mo xianbo, so he won't make a fool of himself. This palace admits defeat!"
So far, Merton vs nine princes.
Total victory.
