Chapter 140: [Vertical Algorithm]

Hearing Li Chengqian's words, the little hand of the little fortune fan paused.

She raised her head to look at Li Chengqian, blinked her big watery eyes, and asked, "Your Highness will pose this?" ”

"No, it won't."

"That's ......" Xiaocai blinked in confusion.

Li Chengqian pulled a piece of paper, picked up the Zhenguan pen again, and after putting it on the shelf, he said to the little wealth fan: "You don't need to calculate the chips, you report the accounts, and I will calculate them for you!" ”

The little fortune fan hesitated to look at the unfinished abacus on the table, and finally listened to Li Chengqian's words, and reported: "Today, the first time I bought linen cloth has always been three hundred and seventy-two yuan, and then I bought six hundred and twenty-nine yuan, and the concubine has to calculate the amount of linen cloth I bought today." ”

Li Chengqian took the Zhenguan pen and wrote on the paper, and as soon as the voice of the little wealth fan fell, he said loudly: "2001 money is two coins and one money." ”

Xiaocai Fan and Su Mi were stunned when they heard this, they were both frightened by the speed of Li Chengqian's accounting, they looked at what he wrote on the paper, what was written on the paper was the addition of Arabic numerals, of course they didn't know it.

Su Mi asked, "Your Highness, what is this word?" ”

"Numbers."

"I haven't seen the concubine body." The little money fan took a serious look at it and said.

Li Chengqian pointed to his nose and said shamelessly: "I just invented it." ”

The little money fan grinned, and then checked it with the calculation.

"How is it different from the numbers in the ledger?" Su Mi took the account book of the little wealth fan and asked.

"Nonsense, if it's the same, do you still need me to invent it?" Li Chengqian said with a smile.

The little fortune fan laid out the calculations, and the result was the same as Li Chengqian's, and he was pleasantly surprised: "Your Highness's result is fast and accurate!" ”

"If you believe it, report the rest of the accounts to me."

"Hehe, the concubine has always believed in His Highness!"

"Well, it's okay to report the number, and you don't need to report the name of the item."

The two of them reported the number one by one, and the other calculated the number by adding it vertically, and then read it to her, and she recorded it in the account book, and the cooperation was very tacit.

Su Mi looked at it a few times on the side, and understood the meaning of the ten numbers from 0 to 9, took a piece of paper, wrote down the ten numbers, and then imitated Li Chengqian's vertical style, and quickly wrote it well, and after a while, she could almost report the number at the same time as Li Chengqian.

"Yo, Mushroom is so smart!" Li Chengqian boasted, and then he was lazy, "Well, I'll look at it, you can count it!" ”

Su Mi raised her head and smiled charmingly, and then buried her head in the calculation.

A bill was quickly settled with the cooperation of Su Mi and Xiaocai fans.

The little fortune fan closed the account book, then leaned over to Li Chengqian's side and said, "Your Highness, can you teach me your magic algorithm?" ”

"Doesn't Xiao Mushroom know, you let her teach!" Li Chengqian pointed at Su Mi.

Su Mi smiled and said, "The concubine body is just written according to the appearance of His Royal Highness, and I don't know how to teach it." ”

"It's easy stuff, you see it's 1 to 9, it's 0. The two numbers are added together, the numbers are aligned, and the full ten is one. Li Chengqian said as he demonstrated it to them.

The two women are smart people, Su Mi just watched it, and he was afraid that it was intentional not to teach the fans of small wealth, but now that he heard the theory that Li Chengqian said, he has a deeper understanding of vertical calculation. Xiaocai fans also have a strong learning ability, and after taking a piece of paper and counting two questions, they will understand.

"That's not right!" Sister Hippo raised her hand and said, "You can't count this thing." ”

"Why can't you get it?" Li Chengqian turned his head and saw that the eldest sister of the hippo was also holding a piece of paper and a Zhenguan pen, and the paper said 1+1=2.

The eldest sister of the hippo raised the paper in her hand and said, "Always add one penny, I wrote it according to your method, and I got 2, is that two or two coins?" ”

Li Chengqian rolled his eyes directly and asked, "Are you deliberately finding fault?" ”

Sister Hippo showed a little grievance on her face, Li Chengqian was stunned for a moment, this time she saw that Sister Hippo didn't mean to make trouble, did she still have the mind to learn? What a rarity!

"I didn't, I just didn't forget it." She said.

Su Mi smiled and pulled over the hippo sister and told her the common sense of the thousand-base system, which is always equal to a thousand copper coins. After the little money fan got started with vertical arithmetic, he was overjoyed, opened her account book, and checked it one by one. After checking the book, she ran back to her room, took three more books, and played a math game.

Su Mi also joined in the fun, and I didn't know where to get a bill, and started playing. Naturally, the hippo sister is indispensable for the lively things, and in the end, the three women have all turned into mathematicians, although only at the elementary school level!

Originally, the evening was the time to tell stories and gamble money, but now that they are playing math games, Li Chengqian is idle. For him, a person who can be lazy, he is naturally very good.

It's just that after a while, he felt too bored, so he told them about the vertical form of subtraction, as well as the vertical style of most of the addition, and won the favor and worship of all the women in the Lizheng Hall for a while!

After the court meeting the next day, Li Chengqian went to greet the queen rain or shine.

But when I arrived at the Lizheng Palace, I felt that the atmosphere was a little wrong.

Su Mi stepped forward with a strange face and whispered, "Your Highness, the queen has not come back yet." ”

"Huh?" The queen is a sick person, where can she go, what does it mean that she has not come back yet?

"The queen stayed in the Manna Hall last night......" Su Mi blinked her eyes and said with a mosquito voice.

Oh, I remembered it, yesterday Li Chengqian took the queen out for a walk, and then went to the Manna Hall because of the pill matter, and finally the queen was pushed by Lao Li to take a walk. But what's the matter with staying in the Manna Hall to sleep all night, is there any need for such a fuss, it's not lost!

"It's okay......" He was stunned halfway through his words, his eyes widened, looking at Su Mi's strange water-colored eyes, and after a while, he shouted: "My day, it's a big deal!" ”

The queen has only taken out the fetus for a few days, and this Lao Li has stayed overnight with the queen!

At the court meeting just now, Li Chengqian was angry with Lao Li, and now when he heard that the queen was staying, he added new hatred and old hatred in his heart, and all broke out!

However, he still cares about the queen first. shouted: "Imperial Doctor, go to the Manna Hall and have a look!" ”

Su Mi pulled Li Chengqian for a moment, and said softly: "Your Highness, the imperial doctor can't just enter the Manna Palace!" ”

"No matter, I'll take it! ...... "Li Chengqian doesn't want the queen to have anything to do."

This Lao Li has so many wives, is it necessary to do this?

He scolded Lao Li in his heart.

"What are you doing so loudly, you kid?" A kind voice rang out.

Li Chengqian and his wife were stunned, isn't this the queen's voice?
