The pier in Qingshi Town is not small. Lin Xiaoyue stood by the river and looked over, and found at least a dozen ships unloading.

There were still ships behind, either waiting in line to dock, or passing by merchant ships that were about to dock.

Lin Xiaoyue observed and found that there was only one broad avenue leading to the town in the entire pier. All the commuters and coachmen Lifu need to pass through this road.

Because there are many people coming and going, there are people on both sides of the avenue who set up stalls to do business, mainly selling food and groceries.

Maybe it was because she missed the working hours at the wharf, and these stalls are not doing much business now.

Lin Xiaoyue observed for a while and then returned to the town.

Then I went to the market to buy some meat and vegetables, and then went to the cloth village to buy the cloth Liu ordered her to buy.

After checking the time, he returned to Ruyi Building.

After ten o'clock, Lin Xiaoyue began to teach Liang Chengcai.

Lin Xiaoyue first checked the homework she left to Liang Chengcai yesterday and praised Liang Chengcai after finding that there were no mistakes.

Only then did Liang Chengcai begin to teach multiplication.

"Multiplication is a simple algorithm for adding and summing the same addends. We often use multiplication in our lives."

"For example, when I sell wild things to Ruyilou, the hare is 15 wen per pound, 3 jin is the sum of 3 15 wen, and four jin is the sum of 4 15 wen. But if we learn multiplication, 3 jin is 15 wen Multiply by 3, 4 jin is 15 wen multiplied by 4. By analogy, 100 jin is 15 wen multiplied by 100, instead of adding 100 times all the time.”

Lin Xiaoyue wrote the continuous addition and multiplication formulas on the paper.

Then I talked to Liang Chengcai about factors, multiplication symbols and the definition of products.

Then he asked Liang Chengcai to list the multiplication formula.

After confirming that Liang Chengcai mastered it, he began to teach Liang Chengcai the multiplication formula.

"This is a table of multiplication formulas. It's my secret to quick calculation. I'll teach you to memorize it now." Lin Xiaoyue said while looking at Liang Chengcai.

"Then your homework today and tomorrow is to recite this table of multiplication formulas, and it must be thoroughly familiar."

"Yes!" Liang Chengcai's eyes were excited, feeling that he was about to learn something great again.

"Yeah." Lin Xiaoyue responded.

Then he pointed the pen to the nine-nine multiplication table he had prepared on the table and began to teach Liang Chengcai to recite it.

Next, Lin Xiaoyue taught Liang Chengcai to read it by himself after only teaching it twice.

Then I had nothing to do when I was idle, and I drank tea and ate snacks by the side, watching Liang Chengcai read and memorize by himself.

Looking at Liang Chengcai's serious recitation, Lin Xiaoyue suddenly felt a little complacent.

She can now probably understand why the teachers in the pre-apocalyptic world liked hard-working children.

Until someone in the back kitchen came to inform Lin Xiaoyue that her family was here.

Lin Xiaoyue looked happy, then put down the cake and immediately got up from the stool.

"That's it for today. You should recite the multiplication formula table well in the past two days, and we will continue the class the day after tomorrow."

Liang Chengcai quickly got up.

"I'll send Miss Lin out." He said quickly.

He was very curious about Miss Lin's family, and he didn't know what kind of family could teach such a woman.

He had met Miss Lin's mother before, but unfortunately he couldn't say a word to her. I don't know what happened to the rest of her family.

In addition, Miss Lin has also taught him the speed algorithm for several days, and it is also a due etiquette for him to send her out.

"No need. Come on!" Lin Xiaoyue carried the basket and walked out.
