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

Chapter 269
She only has this one son, and she will never want to have another son with that bitch man. This is her only treasure.

She doesn't expect her son to be a top student, the top student in high school, she only hopes that he can grow up safely and healthily.

The child nodded sensiblely: "I've grown up now, and I will take care of myself. Grandma doesn't need to worry. I will take care of Grandma in the future."

"Auntie is still young, don't rush to let you take care of her, you can grow up slowly."

Looking at her son, she was full of old comfort in her heart. In the future, she would live by her son.

But she doesn't want to put too much pressure on her son, so she has been saving private money.

In this way, after my son marries a wife and has children in the future, he will have less stress in life.

"Okay, Mom is busy, you should take a rest too."

After speaking, she went back.

On Jiang Zhao's side, he was still reading in the Imperial Academy.

She pinched her fingers and calculated: "The emperor should be drafting soon, right?"

Si Mubai nodded.

After the draft, the emperor should make another big move.

But the emperor must prepare a lot for the draft, and it is estimated that he will have to wait for a while.

Not to mention other things, the nuns who enter the palace for draft need to be trained in etiquette in advance, and after the draft, they need to continue training.

After the balance, Jiang Zhao and Simu Bai went to Chongguang Temple, and they hadn't been here for several days, and they couldn't leave everything to Jiu Qi, they let the shopkeeper go.

As soon as I arrived at Chongguang Temple, I heard the voice of reading characters from inside. There were adults and children.

Jiang Zhao and Simu Bai secretly opened the door and poked their heads inside.

In [-], they were taught to read and write.

Jiang Zhao gestured to Si Mubai, and the two quietly backed out.

"They are in class, let's wait outside now."

Si Mubai nodded.

The two sat outside waiting boredly, and the sound of their reading could be heard from inside from time to time.

This reminded Jiang Zhao that when he was young, when he was learning to recognize characters in kindergarten, the teacher took them with him, and every time he learned a word, the teacher would take them to read it several times.

But she hadn't felt this kind of atmosphere for a long time, and now when she first heard the voice from inside, she felt like she was back in kindergarten.

Jiang Zhao had nothing to do, he took a branch and scratched it on the ground.

She drew grids one after another. She didn't know what to write in the grids, so she just wrote the multiplication table.

"One by one is one, two by two is four, three by three is nine..."

She was talking while writing.

Simubai came over curiously to look at what she wrote on the ground.

Looking at her appearance, what she wrote seemed to be words, but he had never seen this kind of words.

The strokes are much less than the characters they write now, and they can finish writing with a maximum of two strokes.

"What is this?"

He couldn't help asking out loud.

"This is the nine-nine multiplication table. You can understand it as arithmetic."

Simu Bai became even more curious.

"How does this thing count?"

Jiang Zhao casually picked up a few stones from the side, and placed two stones on the left and right sides.

Then he pointed to the two two makes four and said.

"Look at this, two times two equals four, and then look at the stones, there are two on the left and two on the right, are there only four in total?"

"Then this two times three equals six."

As she spoke, she added another stone on each side.

Then he said: "Three here, three here, two piles of three stones, that is three times two equals six."

Si Mubai nodded: "It's just that what's the use of this math? We all know this simple math."

"What I just told you is just the basics. This kind of arithmetic can be used to calculate things with a relatively large base."

"So, I'll come up with a question and see who gets it right first, and I'll use the arithmetic I taught you just now. What do you think?"

Si Mubai nodded: "Okay."

Jiang Zhao read the title slowly.

"There are currently 380 granaries, and each granary contains 240 bags of grain. How many bags of grain are there in total?"

As soon as Jiang Zhao finished speaking, Si Mubai began to count in his heart.

Jiang Zhao also took the branch and drew a formula on the ground.

There were still words in his mouth.

"Three seven 21, two in front, three eight 24, plus two 26 in front, two more in back..."

After a while, Jiang Zhao came out.

"It's 310 eleven thousand and forty-one."

Si Mubai glanced at her, remembered the number of words she had just counted in his heart, and then continued to count by himself. He wanted to figure out whether Jiang Zhao's calculation was right or wrong.

Two quarters of an hour later, Si Mubai turned to look at Jiang and nodded, which meant that he had finished his calculations, and Jiang Zhao's calculation was correct.

It's just that the efficiency is high and low. Jiang Zhao only took less than a minute, but he took more than two quarters of an hour.

This is because his brain is relatively flexible. If it is an ordinary person, it may take a longer time to calculate it.

Suspicion flashed across Si Mubai's eyes. He didn't expect that the ninety-nine multiplication table that Jiang Zhao said was so powerful that it could allow people to complete arithmetic in one minute that would take two quarters of an hour.

With Jiang Zhao's arithmetic ability, he can work in the Ministry of Household Affairs without staying in the Imperial Academy to burn ashes.

After going to the Ministry of Household Affairs, those officials are afraid that they will regard her as a treasure. With her, no matter how huge the number is, they can be calculated within a few minutes.

Jiang Zhao looked at Si Mubai proudly.

"How about it, want to learn?"

Si Mubai nodded, he still wanted to learn about this.

Then Jiang Zhao continued to pick up the branches and finished the nine-to-nine multiplication table that was not finished just now.

Then he began to teach Si Mubai.

The first thing to teach is to let him know these numbers first, and then pick up a branch and hand it to him.

"Write with me, this is one."

Draw a vertical line on the ground.

Then wrote an Arabic numeral two on the ground.

"This is two."

Let Si Mubai know all the numbers from zero to ninety.

After he got a few numbers in his mind, he began to teach him the multiplication table.

"One for one."

"One by one makes one? Shouldn't it be two?"

Si Mubai asked curiously, shouldn't two ones be two?
This is also the reason why Jiang Zhao could avoid one by one when he explained it to him.

Jiang Zhao continued to explain to him.

"One one gets one, which means that one thing has only one thing, so one one gets one, two two gets two, that is, there are two of each of the two things."

"Look at this pebble, there is only one of it, so you get one one by one."

"I'll put another stone in, that means there are two of the same thing, so one and two get two, understand?"

Si Mubai nodded, and after Jiang Zhao's explanation, he generally understood a little bit.

Then Jiang Zhao asked him to memorize the multiplication table, thinking that he had memorized this thing since he was a child.

I didn't expect that after time travel, I could use it here to poison the ancients.
