Calculation

Wang Tian grew up in Shanyin County and knew that this was the usual way to raise prices by peddlers outside the city. He reached out and said, "See if it's worth it."

The little peddler was not worried that someone would rob the goods and ran away. He just told him to "Don't get dirty", and handed the wooden pendant to Wang Tian.

This is a carved wooden ware that is up and down, and both wooden blanks are only the size of copper coins. Pedestrians on the rain road are running with their hands on their foreheads. Countless pits are splashing on the ground. It is obvious that they are hiding from the rain. The whole picture is not rainy; the farmer harvests grains...

A middle-aged man stretched out his palm to Wang Tian and shouted at the peddler: "I bought this item. Is there any good item? Tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk tsk

Wang Tian went back and took care of his elder brother's money, so he gave the pendant to the middle-aged man. When the crowd came out, he heard the young peddler call the peddler Feng, and it was obvious that the two knew each other.

Wang Tian pointed to the ground with his left toe and jumped back to the convoy with his right foot. "Thank you, guess what I saw just now? The peddler sold goods to the peddler."

"And then?"

"Then I didn't have money, so I came back. I'll ask you a question, why do peddlers sell goods to peddlers?"

"One enclosed land and sat on the business, and the other went to the street to go to the business after purchasing goods. Although they were all peddlers, there were merchants, and there were differences between merchants."

Wang Tian jumped out of the ox cart again and limped over to his elder brother: "When my mother gave birth to me, did she touch her stomach?"

Wang Changyu...

"Otherwise, why are the eldest brother smart? Brother Huan and Brother Wen smart, even Hu Zi smart, why are I stupid?"

"You're not stupid."

"real?"

"Well. Remember, whenever you want to talk, especially when you feel that you feel so stuffy that you don't say it, you will breathe five times, and you still want to say it, and then breathe five times. Others think that you are as smart as them, even smarter than them."

“So simple?”

“So simple.”

"That……"

"Shh." Wang Changyu raised his fingers in front of Wang Tian's mouth, indicating that his second brother would restrain himself.

Wang Tian followed the rhythm of the elder brother's chest and undulating. He breathed five times and then five more times.

Wang Changyu patted his shoulder with praise: "You didn't talk back this time. It seems that you have listened to what I just said. This is how growth is going."

Wang Tian returned to the car in a daze.

Xie Ji asked: "Brother Tian, ​​do you know Linmuyuan?"

Wang Tian's chest was fluctuating with exaggerated ups and downs, staring at Xie Di, counting: one, two, three...

Thank you for jumping off the car.

The team slowly moved forward and finally entered the city.

Linmuyuan.

Wang Ge solved the answer to the beast and bird question: Eight beasts and seven birds.

Start carving wood, the shape is similar to a "calculating board".

The outer frame is eighteen inches long horizontally and one foot vertically. A cross beam is added at the middle position of the vertical length. The edges of the beam are only half the thickness of the vertical frame.

Inside the calculation board, there are twenty vertical poles, all of which are four-edge-edge, with each being more than eight points (2 cm).

Ten standing poles are wedged with "six heads and four-legged beasts"; the other ten are wedged with "four heads and two-legged birds".

One animal is beaten by one animal, one animal is beaten by one animal, and in this way, weaving twenty upright poles.

The outer frame and the edge thickness are both two-part and two-part distances (6 mm), and the beam is half-part. The vertical pole should not be too thin, and the entire two-part distance is wide. If it is too thin, it will easily break when children fiddle. The thickness of the vertical pole is more than one-and-a-half (4 mm), and overlaps with the beam with part of the thickness.

The vertical pole is the keel of the beam, and the horizontal pole is the spine of the vertical pole.

Relatively speaking, the calculation board is easy to carve. After determining the size standard, except for the horizontal frame at the top, the rest are carved with whole wood. After wedge the ten beasts and ten birds, we will then splice the top frame to form a complete calculation board.

Jiashe Village.

Wang Sanlang bought grain bags in the miscellaneous house. Originally, there was a bucket of grain in each bag, but it was not like Jiashe Village. He went to the village to sell grain and buy grain, and the grain store also served grain like this.

He just came up with a trick. He poured the grain into a wooden bucket, grabbed one, and pulled the upper grain grains, and couldn't tell that there was less grain. It would be impossible to grab two hands, but one and a half? Put ten grains back, and five grains back...

It’s OK. For each dou of wheat, grab a small handful, take a dozen more pills, and take a look. There are very few in the dou.

You have to be careful when you live and don’t be afraid of trouble. He was so tired that he was sweating all over. In order to prevent mistakes, the tenant farmers grabbed the handle. He poured each bag of wheat into a wooden bucket. After confirming that one handful of grain was missing, he poured it back into the grain bag.

Well? What if you add more than a dozen pieces of bran into it? Wouldn’t you save more than a dozen pieces of grain?

Wang Sanlang was exhausted. While taking a breath, he scolded Wang Zhu: Damn Zhuzi, it was just when he was working, and I don’t know where to go. He really wasn’t a good person. If he had known Zhuzi was stupid, he would have left A Peng!

It was not early afternoon.

Wang Ge stroked his throat, pulled down the wheat cake that was choked on this piece, and then swallowed his saliva. Well, after a while, the water soaked the cake in her stomach, and she would not be hungry.

The calculation board has been carved, and the "Six-Headed Four-Leaded Beasts" have begun to be carved.

The problem-solving requirement is to make arithmetic objects that can arouse children's interest, so you must not literally carve it. No matter what animal or bird, or even a few heads and feet will become scary.

Furthermore, the "six heads and four feet" must be a whole template.

The six areas are all small square pieces arranged in upper and lower rows, two in each row. The tops of the outermost tops of the six square pieces should be tilted to carve very small "ox horns". There are six horns in total. Just use "horns" to mean beasts, and do not carve the faces of beasts.

The cross-sections of the six square pieces cannot be blank, and they are engraved separately. The "Beginning of Spring, Rain, Waking of Insects, Spring Equinox, Qingming, Grain Rain" in the spring of the twenty-four solar terms means "the growth of all things", and this means dilute the children's fear and repulsion of the "six-headed beasts".

The four-legged areas under the template are all rectangular. The outermost lower ends of the four rectangles must be tilted and carved with very small "cow hooves". There are four hooves in total.

The cross-sections of the four rectangular pieces are engraved with "East, South, West, and North", which means "the ox plows in all directions".

From the "six heads" to the "four feet", the vertical grooves are chiseled in the middle of the entire formwork, and the width should be able to be placed in the vertical pole (not too tight), so that the vertical pole is half the thickness, and there is a slight gap with the cross beam.

Since the "six heads" and "four feet" are a whole, pushing the "four feet" is also equivalent to pushing the "six heads". The length of the template must be ensured. Whether it is pulling the "four feet" to the horizontal frame position at the bottom of the wooden plate or pushing the "six heads" to the top of the pole (the uppermost horizontal frame has not been installed), the "four feet" is always under the beam.

Similarly, the "six heads" are always above the beam.

After chiseling the vertical groove, at the top of the beast template, where the bottom end is left (referring to the square wood blocks at the top and the rectangular wood blocks at the bottom), each of which is four groove eyes, for a total of four. Then cut two "small"-shaped wooden blocks and cut tenons. The four tenons and four groove eyes are aligned, and after the size is appropriate, the last step of the first beast template is left.

The template is stuck vertically on the pole, and the two "small"-shaped wooden blocks are clamped down until they can't be pressed. The gap left in the middle allows the beast template to push and pull on the pillar. Because the pillar is square, the beast template will never spin, so it will turn over.

The first beast template was not skilled and took a long time. Wang Ge grinned and moved his back and started to make the second one. He finished making all the beast templates and then made the bird template.

In the afternoon, Shin-zheng time.

Reed Pavilion.

The old couple Wang Weng returned home with a wheelbarrow. Ai sat on his head, and was so happy that he almost burst into laughter. The old couple didn't think there was anything funny at first, but seeing that their granddaughter was so happy, he couldn't stop talking.

Weiting bought five new wheelbarrows, and there are elderly people over 55 years old in the Tinghu family who can get one. This is a big purchase, can the Wang family be unhappy?

"Big Father? Big Mother... Ai, is it Ai?" Wang Zhu finally saw the back of his familiar family, pulled out his legs and chased him, getting closer, getting closer!

When he called "Big Mother", his jaw was already shaking violently, and his tears and snot flowed out.
Chapter completed!
