"Brother! Brother! ”

At night, Liu Shui shouted all the way to Liu Cheng's room.

"Today, 183 servings of braised pork alone have been sold! In addition to the capital, you can also earn thirty dollars! ……”

As soon as Liu Shui came in, he began to constantly report today's earnings to Liu Cheng.

A face turned a little red from being too excited.

"Brother, even if you remove the free tasting dish and the cost of buying one get one free and giving it away, you will still make a net profit of eight thousand six hundred and thirty-one dollars today!"

"Eight thousand six hundred and thirty-one dollars!!"

"Eight thousand six hundred and thirty-one dollars!!"

At this moment, Liu Shui has completely turned into a repeater, and it is the kind that is getting louder and louder, constantly chattering in front of Liu Cheng, and the excitement is beyond words.

It's no wonder he is so excited, when he was in Chenggao's hometown before, his brother killed pigs for others, and after a year, he was busy and tired, but he was only able to earn more than 2,000 yuan.

As a result, now, on the first day of the restaurant's opening, it has earned so much money at once, and it has earned more in one day than in previous years!

Faced with such a scene, how could Liu Shui be unhappy?!

The restaurant can make money, and Liu Chengcheng had expected this at the beginning.

After all, he got all the things that were stir-fried in the iron pot, and at the same time contributed the high-level cooking skills he learned at New Oriental, and on the day of the opening, he also used free tastings and buy one get one free, which is very advanced but very useful.

Under such circumstances, it is impossible for this restaurant not to make money.

However, the numbers heard from Liu Shui's mouth at this time were still a little unexpected by Liu Cheng, which made Liu Cheng a little surprised.

It seems that he underestimated the proportion of foodies among the Han people, as well as the charm of iron pot stir-frying, the power of propaganda methods on the rotten streets in later generations, and the number of rich people in Luoyang.

"Good job! The days will be more and more rushing! ”

Liu Cheng smiled and slapped Liu Shui on the shoulder.

Liu Shui nodded vigorously!

"Brother, you teach me to do the math, all kinds of things need to be calculated, I can't do it, today these are still backed up to help calculate."

After about a quarter of an hour or so, Liu Shui gradually recovered from the excitement of making a lot of money for the first time, and then began to ask Liu Cheng to take the initiative to learn.

For his younger brother's request, Liu Cheng naturally will not refuse, in the future generations, there are not too many children who are so studious and take the initiative to ask for learning.

At that moment, Liu Chengcheng found pen, ink, paper, and inkstone.

Paper was already available at this time, and it could be bought, after all, as early as one or two hundred years ago, the cheap Caihou paper had come out, and it had developed to the present, and the paper that could be used for writing had already appeared.

is the effect of writing, which is not as good as Liu Cheng's common writing paper in later generations.

However, it is enough to teach Liu Shui to learn arithmetic.

After studying the ink, Liu Chengcheng put pen to paper and wrote out the ten Arabic numerals from 0 to 9.

In order to facilitate Liu Shui's memory and facilitate the integration with this era, Liu Cheng wrote down the ten lowercase characters from zero to nine under the ten Arabic numerals, which are considered numbers for people in this era.

Then, with the barrel of a clean brush, point to the number and start reading......

Interest is the best teacher, and people who are extremely thirsty for knowledge have a very high learning efficiency.

It only took a quarter of an hour for Liu Shui to memorize these nine numbers that he had never seen before, and he was able to write them down silently.

Even if Liu Cheng disrupted their order, Liu Shui would not confuse it.

Liu Cheng reversed the order, read it at will, and asked Liu Shui to dictate, and Liu Shui was able to write it well.

Under the eager gaze of Liu Shui, who had reached this point and wanted to start formally learning arithmetic, Liu Cheng cleared his throat, then lifted the ink-stained brush, and once again wrote '+''—'The two Liu Shui had never seen the symbol before, let Liu Shui remember.

Liu Shui, who was full of anticipation and felt that he could finally learn advanced arithmetic, suddenly collapsed.

However, in the next moment, he hurriedly memorized these two unfamiliar symbols by heart.

It's not just about remembering what they're called, what they look like, and how they're written, but also what they mean.

After such a thing was finally completed, in Liu Shui's extremely eager gaze, Liu Cheng took two large pieces of paper and put them in front of Liu Shui, and many things were written on them, all of which were simple addition and subtraction operations within ten.

At the same time, he told Liu Shui to let him answer all the arithmetic problems on these two pages first, and then he taught him more advanced arithmetic.

Suddenly seeing the dense arithmetic questions written by his brother with the special numbers and symbols he had just learned on these two large sheets of paper, Liu Shui only felt that his scalp was a little numb for a while.

He looked up at Liu Cheng, his gaze a little dull.

Liu Cheng smiled: "What are you looking at?" Hurry up and write, write all these questions, add and subtract within ten, you will be able to master it proficiently, and you will be able to learn more advanced arithmetic. ”

Liu Shui soon began the difficult process of arithmetic.

Looking at Liu Shui, who was lying in front of the table and constantly gesturing his fingers to count, Liu Cheng yawned and smiled knowingly on his face.

In the past, I let others assign homework to myself, but now feng shui takes turns, and it is finally my turn to assign homework to others, and I stand here and watch it leisurely.

Not to mention, it's a really nice feeling......
