After the three yuan and the third, the ministers angered the ceremony and the music collapsed

Chapter 270 Arabic Numerals and Nine-Nine Multiplication Table

Si Mubai recited it seriously, at least he was a prodigy, and he recited it without much effort.

"I've already memorized this multiplication table. How did you calculate so many numbers just now?"

He was more interested in Jiang Zhao's schooling just now.

Now that he has memorized the multiplication table, he has a certain foundation.

Jiang Shao began to explain to him the multiplication and division of two-digit numbers.

"Like twelve times twelve, when two numbers are multiplied, the one below must be moved back one, and then two two gets four, and one two gets two. Continue to do the calculations below, and then add the numbers in the upper and lower rows together. Get up, you can see that it will come out, the total is 140 four."

Jiang Zhao explained to him while writing.

Si Mubai carefully looked at the formula that Jiang Zhao listed for him on the ground, as for Jiang Zhao's calculation of the granary just now, it was the same.

"As long as you learn to calculate like this, no matter how complicated the numbers are, you won't be troubled by them. Anyway, all formulas are like this."

Jiang Zhao said.

Then, in order to test whether Si Mubai really knew it, Jiang Zhao casually gave him a number.

"You do the math, 190 seven times 550 two."

Holding the branch in his hand, Si Mubai began to count according to the formula Jiang Zhao gave him just now.

After the formula is listed, it is the content of the multiplication table he just memorized.

List their numbers one by one according to the memorization of the multiplication table.

Then all the numbers are added together, and the final number is the result.

"One hundred eight thousand seven seven hundred and four."

After getting the answer, Si Mubai told Jiang Zhao.

Jiang Zhao nodded, the answer was the same as what she had calculated in her heart.

Teaching knowledgeable adults is fast. At the beginning, their teacher taught them this group of brats, but it took a semester to teach them, and the teacher almost died of anger.

Then Jiang Zhao began to teach Si Mubai how to divide.

After learning multiplication, division is very simple, but it is just the reverse of multiplication.

Although the style of the formula is different from that of multiplication, it will be fine if you look at a few more styles.

After listing a few formulas for Simu Bai, he almost mastered division.

These are just the beginnings of arithmetic, her primary school curriculum.

There are also xy formulas and the like in the back. In short, it gets more complicated as you go to the back.

People in this world only need to master the basics, and there is no need to master the rest.

When she was studying Mathematical Olympiad, she used to have thick hair, but it became more and more bald at the back.

So after mastering the multiplication and division, stop here.

After traveling here, she also has thick hair, but she doesn't want to end up with the same hairline as in the previous life, with receding hairline and bald head, then she will really thank her.

Unknowingly, the class between the two of them has been going on all afternoon, and it is now dark.

In [-], they finally came out after class.

"Why are you here? Why are you squatting here? Why don't you go in?"

Jiuqi, who came out of the house, saw Jiang Zhao and Simubai squatting on the ground, and asked curiously.

Then he saw the numbers written by the two on the ground. He tilted his head from side to side and looked at it, but he couldn't understand what the two of them wrote on the ground.

"What are you writing? It's like a ghost drawing, and you can't even read it."

Jiang Zhao couldn't help but rolled his eyes and said.

"These things are called Arabic numerals."

"I've never heard of any Arabic numerals. Just these characters, if you draw them on paper and sell them as paper symbols, maybe someone will actually buy them."

Jiu Qi taunted, he couldn't let go of any chance to hit Jiang Zhao.

"Then sell it to you, don't worry, I won't charge you, I will teach you for free."

She didn't mind teaching Jiu Qi these things.

On the contrary, she was happy to see Jiuqi bald.

At that time, what is the volume area of ​​the cylinder, the volume area of ​​the cone, and what angle, the chicken and the rabbit are in the same cage...

Give him a lesson, let him experience what social evil is.

"I don't want to learn ghost drawing symbols. I want to learn from you."

He already knows enough things, there is no need to learn some metaphysics.

But Jiang Zhao came up and patted him on the shoulder.

"You have to learn this stuff if you don't want to. I have already taught it to your young master. When the time comes, let your young master teach you personally."

As soon as he heard that it was Si Mubai who taught him personally, he wanted to cry, and he couldn't escape even if he wanted to.

"Can't I not learn?"

Jiuqi cried and said.

But Jiang Zhao rejected him decisively: "No, I have to learn!"

Now that he has decided to hand over the winery to him, these things are the skills he must master.

After learning multiplication and division, accounting will be easier in the future, and the error rate will be very low.

Jiu Qi was already in tears at this time, he just wanted to play and didn't want to go to school, especially since the master in the school was still his own young master, he was even more repelled.

But he still has no way to refuse, so he can only learn from his young master honestly.

Looking at the ghostly symbols on the ground, he felt a little headache.

"Miss, do I really want to learn?"

"Yeah." Jiang Zhao nodded, "I really want to learn."

"Can't you learn?"

"If you don't study, you can't do it."

"How about I die?"

"After learning, go to die."

It seems that this catastrophe cannot be escaped, Jiu Qi closed his eyes with a heroic appearance.

"Okay, just die, I'll learn!"

Jiang Zhao patted him on the shoulder in relief.

"Study hard, and I will cheer you on."

Jiuqi didn't want to talk to him, what to do, just to see his jokes.

At this time, the children from Chongguang Temple and the three children from Zhuzi's family all came together.

"Lang Jun, what do you want to learn, we want to learn too."

Jiang Zhao glared at Jiuqi.

"Look at others, how studious they are, and look at yourself, you can't even compare with a group of children."

Jiuqi wanted to refute, but found that he couldn't refute. Why are children nowadays so eager to learn?
Didn't it mean that children are all stubborn, don't think about making progress, and only know how to eat, drink and have fun?

What's the matter with them?

Still rolling with myself here.

Jiu Qi sadly found that he couldn't turn around a group of children.

Could it be that you can't do it yourself?

Jiu Qi thought in his heart, otherwise why are some children more studious than himself?
No!

He must not let a group of children surpass me, and the prestige I have established these days will be wiped out.

He wants to study hard with his young master, and before that, the little brat would not be able to catch up with him if he patted his ass.

"Master, when you get home tonight, you can teach me the number of this Allah."

"It's Arabic numerals."

Jiang Zhao patiently corrected him.

"Whatever the number, I will learn it when I go back tonight. I must learn this thing."
