106 The Multiplication Table
The dock in Qingshi Town was quite big. Lin Xiaoyue stood by the river and watched. She found that there were at least ten ships unloading cargo.
There were still ships behind that had not docked. They were either waiting in line to dock or merchant ships that were pa.s.sing by and preparing to dock.
Lin Xiaoyue observed for a while and found that there was only one main road leading to the town from the dock. Traveling merchants, coachmen, and laborers all had to pa.s.s through this road.
Because there were many people coming and going, there were stalls set up on both sides of the main road to do business, mainly selling food and groceries.
Perhaps she had missed the working hours at the dock, these stalls did not have much business at the moment.
Lin Xiaoyue observed for a while before returning to town.
Then, she went to the market to buy some meat and vegetables, and then to the fabric shop to buy the cloth that Liu Shi asked her to buy.
After checking the time, she returned to Ruyi Restaurant.
At 10 o’clock, Lin Xiaoyue started to teach Liang Chengcai.
Lin Xiaoyue first checked the homework she gave him yesterday. After finding no mistakes, she praised him.
Then, she started to teach Liang Chengcai multiplication.
“Multiplications are a simple method of finding the sum of additions. We often use multiplication in our daily lives.”
“For example, if I sell to Ruyi Restaurant, wild rabbits are 15 wen per catty. 3 catties is equivalent to three 15 wen, and 4 catties is equivalent to four 15 wen. However, if we use multiplication, 3 catties is 15 wen multiplied by 3, 4 catties is 15 wen multiplied by 4 and so on. 100 catties is 15 wen multiplied by 100, so you don’t have to add 100 times.”
Lin Xiaoyue wrote out the addition and multiplication formulas on the paper.
Then, she explained to Liang Chengcai the definitions of product and multiplication symbols.
Then, she asked Liang Chengcai to solve the problem by multiplication.
After making sure that Liang Chengcai had mastered it, she started to teach Liang Chengcai the multiplication table.
“This is the 9×9 table, my secret to quick calculation. I’ll teach you how to memorize it now.”
“Your homework for today and tomorrow is to memorize the 9×9 table, and you must be very familiar with it.”
“Yes!” Liang chengcai’s eyes were filled with excitement. He felt that he was about to learn some amazing knowledge again.
“Good.” Lin Xiaoyue responded.
Then, she pointed at the multiplication table she had prepared and started to teach Liang Chengcai how to recite it.
After that, Lin Xiaoyue only taught him twice before letting Liang Chengcai read it himself.
Then, since she had nothing to do, she drank tea and ate some snacks at the side, watching Liang Chengcai read and memorize by himself.
Looking at Liang Chengcai’s serious expression, Lin Xiaoyue suddenly felt proud.
She could now more or less understand why teachers liked diligent and studious children before the apocalypse.
A waiter from the kitchen came to inform Lin Xiaoyue that her family had arrived.
Lin Xiaoyue’s face lit up. She put down the cake and immediately got up from the stool.
“That’s all for today. Just memorize the 9×9 table for the next two days, and we’ll continue the day after tomorrow.”
Liang Chengcai quickly got up as well.
“I’ll send you out.” He hurriedly said.
He was very curious about Ms. Lin’s family, wondering what kind of family could raise such a woman.
He had seen Ms. Lin’s mother before, but unfortunately, he had not been able to speak with her. He wondered who her other family members were.
In addition, Ms. Lin had been teaching him for several days, so he should be polite and send her out.
“No need. Good luck!” Lin Xiaoyue picked up the basket and walked out.
