So the Cui brothers and sisters went down the mountain early in the morning, picked the yellow buds, Cui Yuanjian took Uncle Guo's ox cart to Yuexiang Pavilion, and Cui Xiaoxiao and Cui Yuankang wrote big characters at home.

Cui Xiaoxiao's big characters are twice as big as Cui Yuankang's, there is no way to write the brush words Cui Xiaoxiao's writing is not good, even a big character can be written into ink balls, which makes Cui Yuankang laugh at it.

For this reason, Cui Xiaoxiao deliberately made a sand table, accustomed to the casual hard pen, for the brush to write under the pen need to control the strength of zhì, according to the thickness of the line, from time to time need to lift the pen to press the pen, into the pen, line of pen, pen are particular, for a time Cui Xiaoxiao is really not used to it.

Practice on the sand table every day, and then practice on paper.

After Cui Yuanjian returned, the three brothers and sisters studied arithmetic problems together. Since Cui Xiaoxiao taught Arabic numerals and ninety-nine multiplication tables, Cui Xiaoxiao knew that this world is not without multiplication, and there are ninety-nine multiplication formulas.

It's just that there are no Arabic numerals here, and it is impossible to do cross-multiplication calculations in your mind, and mental arithmetic has no advantage.

The abacus here is quite mature, and the abacus mantra is not much different from that of later generations. Since Cui Yuanjian found out that Cui Xiaoxiao couldn't abacus, Cui Yuanjian and Cui Yuankang put pen to paper to calculate when calculating, and Cui Xiaoxiao could only dial the abacus beads.

At this time, most of the arithmetic was produced by practical application, and these problems could be solved by later generations of elementary school students.

Cui Yuanjian also strictly forbade Xiaoxiao and Yuankang to show Arabic numerals in front of people, and the faster arithmetic makes people feel smart at most, and it is easy to arouse the concern of people who have a heart out of nothing.

These questions are some of the questions that Cui Xiaoxiao came up with according to the units of measurement of this era, and they are nothing more than the problems of buying and selling and land calculation.

Once Cui Xiaoxiao had the problem of chickens and rabbits in the same cage, it seemed to open a door for the world of Cui Yuanjian and Cui Yuankang, and the two of them were crazy obsessed with this kind of problem.

Cui Xiaoxiao racked her brains every day to think about problems, and her hair obviously fell out a lot (pulled down), and once Guo Shouyi saw it, he was also interested, watching the three of them discuss with great interest.

Cui Xiaoxiao bit his finger beside him, do you want to tell them that this is a very simple matter of a binary equation! Forget it, after all, it is still a very puzzle game to solve problems without knowing equations.

Cui Xiaoxiao stared at the new toy, carrying Jinbao to teach him to add and subtract, and Xiaohui also learned arithmetic with ingots on the side.

Illiterate can live a lifetime, but you can't live a lifetime without accounts.

In order to be vivid and interesting, Cui Xiaoxiao also drew an apple or pear in a stick figure and asked Jinbao to look at the picture and do the question.

Jinbao is still very smart, and the addition and subtraction within ten days can be calculated correctly.

On this day, Cui Xiaoxiao gave Jinbao a question. Jinbao didn't get it right a few times.

Cui Xiaoxiao asked, "How many handkerchiefs are there?" ”

Jinbao replied, "Kujo." ”

"How many handkerchiefs hang from that rope?" Cui Xiaoxiao continued to ask.

"Two." Jinbao said.

"How many handkerchiefs are still hanging in that basin?" Cui Xiaoxiao asked.

"Four-of-a-kind." Jinbao didn't even think about it before he said the answer.

"How many?" Cui Xiaoxiao dug out his ears and continued to ask.

"Shijo." Kimble replied.

After doing this a few times, Cui Xiaoxiao gave up and asked through gritted teeth, "Why Sijo?" ”

Jinbao pointed to the basin on the picture and said, "Aren't all the ones that are not hung in the basin, there are four in the basin, that is, four." ”

Cui Xiaoxiao was speechless for a while.

"What is nine minus two?" Word by word came out of Cui Xiaoxiao's mouth, Cui Xiaoxiao was really afraid that she would abuse the child if she couldn't help it.

"Seven." Jinbao counted on his fingers and said the answer, "Xiaoxiao, why are you asking this?" ”

Cui Xiaoxiao held a breath in her chest, she couldn't go up or swallow, she was really angry.

With his eyes closed and a few long breaths, Cui Xiaoxiao continued to ask, "This question first told you that there are a total of nine, and then told you that there are two on the rope, is it an addition problem or a subtraction problem?" ”

"The problem of subtraction." Jinbao said, "Oh, the answer to this question is seven." ”

Jin Bao came to his senses and touched his head, "Didn't you draw as much as you answered before?" ”

Cui Xiaoxiao held a mouthful of old blood in his throat, so he blamed me.

"I draw a few in the basin to mean that there is a handkerchief in the basin, not necessarily the answer, can not count the number on the picture in the future, remember?" Cui Xiaoxiao said, anyway, it is not his fault that Jinbao miscalculated, no, it was not his own fault.

"Oh, I remember." Jinbao said, "Can you give me a few more questions?" ”

Cui Xiaoxiao drew a few questions, and let Jinbao count it aside, no, she had to slow down, otherwise Jinbao would be angry to death.

"Xiaoxiao, don't be angry with him." Xiao Hui covered her mouth and was happy.

"You're still laughing." Cui Xiaoxiao glanced at Xiaohui.

"Don't blame Jinbao, it turns out that you can still count the answers from the picture. That kid is weirdly smart. Xiaohui said.

"That's smart, that's smart." Cui Xiaoxiao said angrily.

"Cleverness is also smart, no, the original question can still be counted like this, no, I'm happy to die, let me laugh." Xiao Hui clutched her stomach and smiled crookedly.

"You." Cui Xiaoxiao puffed out his cheeks and hit it with a small fist.

"Xiaoxiao, why are you still angry, don't you think it's funny?" Xiao Hui asked, hiding from her little hand.

The whole incident was very interesting, but not one person thought about how the teacher in the incident felt. Cui Xiaoxiao continued to wave her fists, smiling like a flower, "It's very interesting, Sister Xiaohui, isn't it also fun for us to do this?" ”

Cui Xiaoxiao flashed her big eyes and looked at Xiaohui with a smile.

Xiao Hui shouted in her heart, "Oh no, the little rabbit is fried", Xiao Hui is very distressed, why is this little rabbit in her family so short-tempered in appearance?

"Okay, okay, Xiaoxiao won't make trouble, Sister Xiaohui is wrong, how about Sister Xiaohui help you stack ingots?" Xiao Hui Chong Cui blinked and whispered.

"Yes, yes." Someone helped him stack ingots, and Cui Xiaoxiao was very happy.

Cui Yuanjian set a new rule, Cui Xiaoxiao and Cui Yuankang who are not serious in writing, who stacks the hundred ingots the next day.

Unfortunately, yesterday Cui Xiaoxiao was a little frizzy, and the words were not written well, and today it is Cui Xiaoxiao's turn to stack ingots.

Looking at Cui Xiaoxiao, who was happy to bloom, Xiaohui was also puzzled. You say that you can read this little book well, but this hands-on work can't be done.

I haven't learned it until now, but this ingots can be stacked, but I don't like to do it. When it was time for Cui Xiao to stack ingots, she bullied Jinbao and asked Jinbao to fold it for him.

Every time I see Jinbao folding the ingots and looking grateful, Xiaohui can't bear to look at it, that doll is so sincere, Cui Xiaoxin believes anything.

Cui Xiaoxin stacked ingots can exercise patience, and that kid will be all stacked. (To be continued)
