Wang Weiwei no longer thinks about things that make sense, after all, it hurts brain cells too much, and she really can't afford to hurt her without many brain cells.

Lying on the farm waiting for the sunset, she almost forgot that the real world is not connected with the time here.

Out of the Atlanta farm, it was still early, a few hours before dusk.

Wang Weiwei, who had nothing to do, planned to go out for a walk, and unconsciously walked to a small courtyard, where Zhang Jia minus squatted in front of the stone table, and the brush in his hand was writing on the paper and stopped, which should be completing the math homework assigned to him by Wang.

"Second Sister Wang." Zhang Jiajie saw Wang Weiwei outside the courtyard, jumped up happily, ran to the gate of the courtyard, and said, "Second sister Wang, come in and sit." ”

Wang Weiwei walked into the courtyard, came to the stone table, picked up the paper on the table, today Wang Weiwei taught Zhang Jia and Minus how to distinguish between double numbers and singular numbers, and then asked him to go home and write out the arithmetic within a hundred, because Zhang Jia and Minus will not be a basic multiplication and division plan, so Wang Wei taught him a most stupid method, let Zhang Jia and Minus remember the odd and even numbers in the single digit, and then use the single digit to find the ten digits.

"The homework is well done." Wang Weiwei said with a smile.

Zhang Jiajie scratched his head embarrassedly, and said with a smile, "Second Sister Wang, I haven't finished looking for it yet." ”

"Then you go ahead." Wang Weiwei put the paper on the stone table, and then walked around the courtyard alone, Zhang Jiaminus began to do his homework seriously, there were many strange patterns painted on the courtyard wall, Wang Weiwei couldn't understand and asked, "Zhang Jiaminus, what are you painting on the wall?" ”

Zhang Jiajie put down the pen and ran over, looked at the pattern and suddenly smirked, and said, "This is all blind drawing when I was bored, this is a chicken, a duckling and a rabbit." ”

"What does it mean to have a chicken with a duck and a rabbit?" Wang Wei asked puzzled.

"In terms of the number of legs, a chicken and a duck are the same as rabbits." Zhang Jia and minus explained.

"You have a long string of centipedes, right?" Wang Weiwei pointed to something oddly shaped.

"Uh-huh." Zhang Jiamin nodded vigorously, and said with a smile, "Second Sister Wang, you can see it, it seems that my painting is not bad." ”

"No, no, don't get me wrong." Although Wang Weiwei didn't want to hit Zhang Jia or Minus, but these paintings were too ugly, Wang Weiwei said truthfully, "The main thing is that it has a lot of feet, and among the animals I can think of, centipedes have so many feet, so what do you use to add up to centipedes?" ”

Zhang Jiaminus pointed to the patterns on the wall and explained to Wang Wei one by one, "A puppy, three sparrows, and two turtles." ”

"You're good at math, but this painting needs to be improved, hahaha." Wang Weiwei laughed for a while, his stomach hurt a little from laughing, and he pointed to the corner of the wall and said, "Is this a fish?" ”

"A rooster and a fish are equal to the feet of a great white goose."

"When I saw your patterns, I suddenly remembered a math problem."

"What is a math problem?" Zhang Jiajia looked at Wang Weiwei with his inquisitive eyes.

"It's like the one on your wall, where you give conditions and then find the result, do you want to know?"

"Hmm." Zhang Jiajie stood up and nodded vigorously.

"Plus and minus, who are you talking to, are you a guest at home?" An outsider walked in, a middle-aged woman carrying a vegetable basket, dressed ordinarily, without any dress, looking completely like a mountain village woman.

"Grandma, it's the second sister of Wang." Zhang Jiaminus said.

Wang Weiwei looked at the person who walked in outside, pondered for a while, and suddenly thought of who this person was, she was Aunt Zhang that Yunqing mentioned to Wang Weiwei before, and she was also Zhang Jiamin's grandmother, the first gossip king in Shanshui Village.

"It's the second girl." After Aunt Zhang saw Wang Weiwei, her expression looked very unnatural, and she was at the door for a while, not knowing whether to retreat or advance, and she didn't know where to put the vegetable basket in her hand for a while.

"Hello Aunt Zhang." Wang Weiwei said with a smile, pretending not to know about her spreading rumors.

Aunt Zhang also thought that Wang Wei didn't know, so she relaxed, slowly walked to the middle of the courtyard, put the vegetable basket on the table, and said, "Plus and minus, the second girl Wang came to the house as a guest, you don't know how to make tea and take out fruits to entertain, it's really ignorant." ”

"I'm going to ...... now"

"No need Aunt Zhang, I'm just shopping around, and I'll take a look at how Zhang's addition and subtraction homework is doing by the way, it's not more troublesome than this."

"It's okay, it's okay, you don't have to be polite to my aunt, just treat it as your own home, sit casually, stay for dinner at night, the vegetables I just picked in the field are delicious, my family adds and subtracts these vegetables and vegetables, and you can eat a few bowls of white rice at a meal."

"This is really not necessary, my sister is still waiting for me to go back to cook for him, I will give Zhang Jia and subtraction a math problem and go back." Wang Wei shirked.

"That's okay, add and subtract, you should study with the second girl Wang, I'll make a pot of tea for you, the second girl Wang, you teach my family to add and subtract, he is smart, he likes to count some strange things since he was a child, you see the wall of the courtyard, there is no place he let go, you go to class well, I won't bother you." After speaking, Aunt Zhang took the vegetable basket and went into the house.

Glancing at Aunt Zhang's back, Wang Weiwei smiled and said, "Your grandmother is quite enthusiastic." ”

"My grandmother is like this, don't be surprised by Second Sister Wang." When Zhang Jiajie said this, his tone seemed unusually mature.

Wang Weiwei and Zhang Jiaminus sat down in front of the stone table, Wang Weiwei took the brush and paper, began to write and draw on it, and said, "The topic is like this, if you keep rabbits and chickens in one place at the same time, there are eighteen rabbits and fifty-two feet, how many rabbits and chickens are there?" ”

Zhang Jiaminus took the paper, on the paper Wang only drew a circle very vividly, in which a rabbit and a chicken were drawn, and then used a few small dots instead of other rabbits and chickens, and wrote the numbers next to it.

"The rabbit and the chicken are kept together, and there are eighteen in the number of heads, and fifty-two in the number of feet, and how many rabbits and chickens there are."

Suddenly, Zhang Jiamin's pupils dilated, his mouth couldn't be closed, and he was very excited when he saw it, and said, "Wow, Second Sister Wang, how did you come up with such an interesting thing, it's much more interesting than what I painted on the courtyard wall." ”

Wang Weiwei sighed helplessly and said, "Seeing your excitement, I thought you had figured it out." ”

Aunt Zhang came out of the house, carried a teapot and teacup in a wooden basin, poured the tea herself, and said, "There is no good tea at home, just ordinary fried green vegetables, I hope the second girl Wang will not dislike it." ”
