Becoming a stepmother of three children gives me space

After the new house was finished with the beams and the roof was sealed in two days, the next step was the interior decoration.

The original plan for the floor and walls was to smooth them with glutinous rice mortar and then use sticky mortar to whitewash them. However, this plan was unanimously opposed by Uncle Tang and Zhou Jin.

"Unlucky."

In traditional Chinese culture, white is associated with funerals, so large areas of white often mean death and sadness, and people will try to avoid using large areas of white.

According to traditional Feng Shui, white corresponds to the west, is metal, and represents coldness and killing.

The ancients admired vitality and firepower, and the bleak white was not liked. In many special occasions, such as weddings and sacrificial activities, white was absolutely not allowed to appear.

Xiao Yunxi listened to the advice and settled for the second best, smoothing the surface with glutinous rice mortar and wrapping it with wood 1.5 meters from the ground, similar to the decoration style of the 90s.

The floor should be paved with wood flooring, the technology in this area is very mature, but the budget is seriously over budget.

"140 taels of redwood, 38 taels of ash powder and glutinous rice, 8 taels, 300 wen for the workers, and 29 taels for the water trough on the hillside."

Xiao Yunxi reports the expenses and Niuniu is responsible for recording.

Ever since discovering that Niu Niu had a talent for mathematics, Xiao Yunxi had focused on training her, and Niu Niu's intelligence was beyond her expectations.

She has fully mastered the mixed operations of addition, subtraction, multiplication and division, fractions, measurement unit conversion, geometric figures, and area calculation, which are the third-grade courses in modern primary schools.

Niu Niu is only 3 years old, but she mastered 3rd grade math knowledge in just 1 month. It is no exaggeration to say that she is a genius.

In order to train her, Xiao Yunxi gave her the difficult task of bookkeeping.

Keeping accounts may seem simple, but it can actually help children develop their logical thinking.

Calculating income, expenditure and balance can improve basic arithmetic skills, and analyzing and comparing different types of income and expenditure can enhance logical reasoning and data analysis skills.

By keeping accounts to plan budgets and control expenses, you need to use mathematical logic to formulate reasonable financial plans and judge the rationality of various expenditures.

The younger you are, the more you can train yourself.

The little guy sat seriously on a small stool, recording the account stroke by stroke. The content was a bit messy, with numbers, graphics, and strange letters.

Zhou Jin was confused and refrained from asking so as not to disturb her daughter who was working hard.

"Niuniu, have you remembered it?"

The little girl raised her little face and looked at Xiao Yunxi with pride:

"Okay, mother!"

Pat her head:

"Niuniu is awesome! I'll give you a candy as a reward."

"Thank you, mother."

Zhou Jin finally couldn't help but pointed at the part of the account book that he didn't understand:

"what is this?"

It was a very long rectangular block.

"It's wood. Daddy is so stupid."

"What about this?"

There is a vertical stroke below the circle, and two left and right strokes, and another left and right stroke at the bottom.

"It's the worker uncle."

"The hole in the middle of the circle is a copper coin. What does the dot in front mean?"

"That's Mia."

“…”

Niuniu is good at math, but she is only three years old after all, so she doesn’t know many words. Many words are replaced by pinyin or pictures.

The big ingot is silver, and the hole in the middle of the circle is a copper coin.

The triangle on the square means a shop.

The brick is a rectangular block, and the offering is a little man in the square.

Children have rich imaginations and can think of graphics to replace them. Zhou Jin was not surprised. What surprised him was that Niuniu could actually make a table of the family's income and expenditure.

What was even more shocking was that Niuniu's calculation speed was very fast. Xiao Yunxi reported more than 10 projects, and Niuniu calculated the total expenditure in the blink of an eye.

He presided over the investigation of many corruption cases. Just this amount of money would take the officials of the Ministry of Revenue at least a cup of tea to calculate.

"Niuniu, you didn't just write this casually, did you?"

Niuniu was very angry when her profession was questioned.

"Daddy looks down on people, humph."

"Then let me test you..."

"Questions please!"

"Grandpa Tang has 12 chickens and 3 geese. Each chicken costs 35 wen, and each goose costs 40 wen. How many wen did they sell for in total?"

"The chicken is 420 wen, the goose is 120 wen, a total of 540 wen!"

The girl didn't even think about it and gave the answer.

Is it that it doesn’t matter whether it’s right or not, as long as it’s over quickly?

Zhou Jin took a pen and did the calculations, and found that the answer was actually correct. He then asked two more math problems, and Niu Niu answered them both correctly.

"I'll give you an even more difficult one, from Sun Tzu's Mathematical Classic. There's an object whose number is unknown. Now, there's an object whose number is unknown. Count three times three and there's two left. Count five times five and there's three left. Count seven times seven and there's two left. How many are there?"

Niuniu was really stumped. She scratched her head and looked at her mother.

Xiao Yunxi smiled:

“娘给你翻译，就是被3除余2，被5除余3，被7除余2的一个自然数。”

Niuniu looked delighted:

"It's 23!"

Zhou Jin widened his eyes. It turned out that Niuniu didn’t know how to do it, but she just didn’t understand the questions!

"There are chickens and rabbits in the same cage. There are thirty-five chickens and rabbits on top and ninety-four legs on the bottom. How many chickens and rabbits are there?"

Xiaobao is a little dissatisfied:

"Dad, can't you ask some difficult questions?"

“…”

Is the problem of keeping chickens and rabbits in the same cage very simple?

"Don't brag, tell me the answer."

Niu Niu had already figured it out, but when she saw Xiao Bao picking up a pen and starting to calculate, she chose to remain silent, still wanting to save some face for her brother.

“X+Y=35，2X+4Y=94.....鸡23只，兔子12只。”

Zhou Jin's confused face:

"X? Y? What are they?"

"Dad is so stupid!"

"fool!"

Zhou Jin was looked down upon by Niu Niu and Xiao Bao, and he began to doubt his life. Are kids nowadays so capable?

The ministers of the imperial court solved the problem of chickens and rabbits in the same cage by doing the reverse calculation. They assumed that there was only one rabbit, then two, three, and started counting. If the number was small, it was not a big deal.

If the number is large, it is impossible to count them all.

Xiaobao's method seemed simpler, but he didn't understand the principle.

"No, I'll ask another question!"

"Daddy is unfair, we also want to ask questions."

"Yes, my question is: there are 100 horses and 100 tiles. The big horse carries three, the medium horse carries two, and two foals carry one. Question: How many tiles are there in total, the big horse, the medium horse, and the foal?"

Xiaobao put his hands on his hips:

"My question is even simpler. Use this chopstick to measure the height of the old locust tree at the entrance of the village. Don't get too close to the tree. If you lose, prepare the materials for the toy Mom designed!"

"It's a word."

Zhou Jin still couldn't believe it. How could such a simple question stump someone as clever as me?

Dabao looked at his father with eyes full of sympathy. He had not learned the geometric relationship of similar triangles, so it seemed difficult for him to calculate it.

Niu Niu held her finger in her mouth and tilted her head. Should she tell her dad the answer secretly?

I really like the big toy designed by my mother.

Grandpa Tang can't do it, but if Dad can, then it's better not to tell Dad the answer.
