Transform randomly in Kexue World

People always have the idea of ​​changing the future at some point, and this is true for great detectives, and Martin is no exception.

Ma Wu, who came back from the future, is not very smart. Although his ability to see through people's hearts and his ability to easily find traps are the same as Martin's, he is clumsy in many technical matters.

Especially her ability to modify data. If she could understand elementary particle physics or learn alchemy in a magical world, she would have a very good performance, but this child just couldn't learn it. Although she found another way to refine the data polymer of the "Lord God" and learned the hand-rubbing system, Martin still felt a little sad when he thought about it.

According to Future Ma Wu, Ma Jia once forced her to memorize those physics definitions, but she just couldn't understand them. No matter how she looked at it, it was because she didn't lay a good foundation when she was young and couldn't develop scientific thinking. Me in the previous world line, have you slacked off?
So the boy who slayed the dragon eventually became a dragon. Martin, who was forced by his parents to study, now turned around and urged Ma Wu to study. He even achieved the highest level of supervision which was to accompany him in class, fearing that Ma Wu would fall behind.

The most frightening thing for children in class is lack of concentration. In the previous Chinese and English classes, Martin could actually notice Ma Wu's distraction - for example, if there were suddenly two water bottles on a classmate's desk, or if there was more water in the bottle, it must be that Ma Wu was distracted and looking at other people's water bottles.

However, Martin didn't pay attention to her in the first two classes. Anyway, both Chinese and English classes were just repeated learning of words. And the attention span of primary school students is indeed limited. If she was asked to concentrate in the first two classes, she would definitely not be able to concentrate in the third class.

So Martin just silently erased the abnormal phenomenon that occurred once every three minutes on average, and then paid close attention to the teacher's teaching level, and replaced him if his teaching was unreliable.

After the break, it was time for math class. Martin not only reminded Ma Wu to listen carefully in class, but he also focused on it himself... However, as soon as he opened the textbook that Conan handed him, Martin was stunned.

This class is about the recognition of numbers within 20.

Well, numbers within twenty, to be precise, the ten numbers from 11 to 20.

This book has a total of ten units. This is the content of the ninth unit, and the tenth unit is about addition and subtraction within twenty.

This book has 107 pages in total, and it only talks about addition and subtraction within ... Can students understand the page numbers?

There are 28 students in this class including the two new ones. If today's primary school students need to be taught to count to 20, do they know how many classmates they have?
Isn't this a pure waste of life?

Just when Martin thought that this thing didn't need to be explained, he saw that as the course progressed, the math teacher introduced the topic of "What should we do when we encounter numbers greater than ten?" Yuan Tai looked at the ten fingers on his hands, and was worried that his fingers were not enough.

Originally thought Yuan Tai was an exception, but when Martin turned his head, he saw Ma Wu also looking at the seven fingers of his left hand and the twelve fingers of his right hand worriedly.

Oh, just one left.

Martin didn't even have the heart to restore Ma Wu's fingers, so he tore off some paper and started writing a small note.

Conan, who was about to lie down on the table to sleep, was attacked by another note.

Martin: {Is this what kids learn nowadays?}
Conan shrugged, wrote his reply on the back of the note and threw it back.

Conan: {It's a little different from ten years ago.}
Martin recalled that when he was in school, he was not the most hard-working. When he was in kindergarten, he was taught addition and subtraction of hundreds.

It is true that the teaching progress is partially repeated in elementary school, but Martin remembers that he started learning multiplication at the latest in the second semester of the first grade. During the first winter vacation in elementary school, no matter what role he became, his sister would pinch his head and make him memorize the multiplication table on his pencil case before school started.

Martin's note was thrown again.

This time Conan didn't catch it, and the note hit Haibara Ai on the head.

Haibara Ai, who was sleeping on the table, immediately turned her head and stared at Conan with resentful eyes: If I can't sleep well, I can't do research at night; if I can't do research at night, you won't have the antidote to take; if you don't have the antidote to take, the kid in the agency may not marry anyone, understand?
Got it! Conan responded with a wry smile, then pointed at the note and Martin: You can't blame me for this.

Conan can pretend to listen carefully in class. The main reason why he sleeps in class is that if he doesn't sleep, the teacher will ask him to wake up Haibara Ai, and Haibara Ai is much harder to deal with than the teacher. So after Haibara Ai lies down to sleep, Conan usually lies on the table and turns into Tongtian Juezhu.

Leaving a warning look, Haibara Ai lay back down, and Conan unfolded the note.

Martin: {Is there no concept of preschool education now? I remember that some of my junior high school classmates studied this major in college?}
Throw it back.

Conan: {Maybe I need to teach you some more basic things, such as how to eat with your mouth.}
Martin flipped forward to see what the first few units of the textbook were talking about... Wow, it started with distinguishing between up and down, front and back, left and right, then taught how to distinguish between long and short, big and small, and tall and short. After finishing with addition and subtraction within ten, it first taught how to recognize circles and triangles and then came today's recognition of numbers within twenty.

To round it off, this can also be considered as an interspersal of number and algebra content and space geometry content.

Martin: {It’s so easy to be a parent nowadays, can you just give birth to a vegetable and throw it to the school?}
I have heard of the reduction of the burden, but I always thought it meant less homework, not that it started with reducing IQ. Martin sighed, he didn't expect that the textbooks would change so much after 18 years.

Let’s take a look at the results of reducing the burden...Martin looked at Ma Wu who was counting on his fingers. His math ability was not even as good as Tuji’s.

This child is useless.

On the podium, the math teacher took out a bunch of chopsticks, a total of 20 chopsticks. Then he took out a dozen chopsticks and led the students to count the chopsticks in order to help them understand the decimal system.

"One... two... three..."

"Look, with so many chopsticks put together, isn't it troublesome to count them? Let's tie dozens of chopsticks into a bundle first, and then count the others, one, two... hm?"

The math teacher remembered that he should have taken twelve or thirteen chopsticks, so why did he still have seven chopsticks in his hand?

Then I'll just count to seventeen in one go, it won't be a problem...

"...six roots, seven roots...eight roots, nine roots, ten roots. Classmates, what should we do now?"

"Tie them into a bundle." The children said in unison. The math teacher looked at the small handful of chopsticks still left in his hand and continued to count with the students.

Martin deliberately did not stop Ma Wu's superpower from getting out of control this time, and forced the math teacher to speed up the teaching progress. The teacher didn't have enough rubber bands to tie chopsticks, so Martin created several rubber bands out of thin air.

It was not until the math teacher had tied the fifth bundle of chopsticks that Martin stopped the endless fission of the chopsticks, but he did not change the number back. The sweaty teacher held the last six chopsticks in his hand and finished counting.

But the teacher was really confused, because these twenty chopsticks were teaching aids that had accompanied him for many years and had always been kept in a drawer. Why were there so many of them today? It was as if they had just been stolen from the cafeteria.

Then the teacher wrote 56 on the blackboard and explained to the children that the '5' represents five bundles of ten chopsticks, which is five times 5, etc...

The next step is to continue counting chopsticks, strengthening the children's numerical sensitivity through repeated practice, until they count ten chopsticks and move them directly one place instead of bundling them into a bundle.

Then Martin discovered one more thing. As long as he started counting chopsticks, Ma Wu would inevitably make the number of chopsticks start to change. Most of the time, it increased, but there was one time when it decreased.

Afterwards, the teacher asked everyone to do counting exercises in the textbook, and Martin confirmed that no matter which question Ma Wu did, the numbers would change and the shapes would increase.

No wonder this child can’t learn. She didn’t receive any digital education before school age, and then she gained this superpower when she grew up. As long as she perceives the existence of numbers, the superpower will make the numbers change.

Considering the fact that Ma Wu pronounced him as an old man, Martin took out his mobile phone during class and silently added a few items to the memo.

【Mawu Growth Rules】

[Rule 1: Do not mention in front of Ma Wu that this world is made up of 'ten' small worlds.]

[Supplement to Rule 16: Remember, the number of small worlds in this world is the sum of nine and one, the sum of the number of a person's fingers, and the next integer after counting to nine, expressed in one Chinese character or two Arabic numerals, which is A when converted to hexadecimal.]

[Rule 2: Do not explain the concept of pi to Ma Wu before you are fully prepared, and do not recite or list pi in front of her.]

[Supplement to Rule 2: There is a temple and a pot of wine on the top of a mountain. You are happy but I am miserable. Drink the wine and it will kill you... When the value of pi makes you feel strange, immediately set pi to the digital homophone of the above words, then go to other worlds to reconfirm pi and overwrite it.]

Rule Three…

[…Rule 10: Do not let Ma Wu see any of the contents of this rule. This rule only has ten items, and the numbers are the same as those in Rule 1.]

Writing some weird rules is one of Martin's hobbies. This memo is just to remind himself how to avoid Ma Wu from causing big dangers. The supplementary part of each rule is to prevent Ma Wu's ability from adding cognitive distortion effects, which may make him forget the correct number.

While writing the memo, Martin was constantly resetting Ma Wu's textbooks to prevent the numbers in the textbooks from being affected by Ma Wu's abilities.

But as soon as Ma Wu counted, the number would be affected, and Martin would immediately reset it. But the change in the number affected Ma Wu's counting, and Ma Wu had to count again, and then it changed again, and the progress of counting was zero.

Must we restore the changes before they affect Xiao Wu? Hum, isn't this the purpose of my merging ten worlds? This new stage is very resilient, hold it down!
Martin was so passionate about his own thing, and no one except himself knew the struggle behind it.

If it was my sister, what would she do? Would she just hide the whole book out of anger?

However, my sister has mastered this ability for many years, and she has already used it in many ways. For example, she can set upper and lower limits for numbers, and the part that exceeds the upper limit will be automatically hidden?

As he was daydreaming, Martin felt a shadow looming over him.

When I looked back, I saw the math teacher standing behind me, and he obviously saw me taking out my phone to edit the memo.

"I'll keep your phone for you first. We can discuss this matter after school. Is there any problem?" The math teacher said mercilessly, even to a transfer student who arrived on the first day and had a mysterious and powerful family background.

And looking at Martin, who was clearly a transfer student on the first day, the math teacher always had an inexplicable sense of crisis when looking at him, as if this kid would stand up the next moment, accuse the girl sitting next to him of pulling up her pants, and then fight with her in class.

"NO idiot~" Martin glanced at the time. There was still one minute and twenty seconds left before the get out of class ended. If he wanted to play any tricks on the teacher, it would definitely affect his lunch time. So he just made an OK gesture with his fingers, turned off his phone and handed it in.

Eating is the most important thing in the world. Eating is much more important than mobile phones. When you need it urgently, you can just snap your fingers and it will be back.

The math teacher left, the bell rang on time, and then it was time for dinner.

Martin leaned back in his chair, his head bent as if on its side, and heaved a long sigh.

"It's rare to see you look so tired." Conan helped bring Martin and Ma Wu's lunch boxes over, and then seeing Martin's look, he couldn't help but ask, "Did you do anything very exhausting?"

Even though Conan wasn't listening to the class, he noticed all the strange things that happened during the class, especially at the end of the get out of class, when the math teacher left with a bundle of more than a hundred chopsticks, and he looked very confused.

As for the incident where the math teacher was mistaken for a cafeteria staff member responsible for delivering tableware because he was holding a large number of chopsticks not long after leaving the school, let’s not talk about that for now.

"The biggest limitation of letting my sister take care of Xiao Wu is the mana bar, but I don't have this limitation, and there is no consumption." Martin first denied it, and then sighed: "Although I don't have a mana bar, I will be tired."

The lunch for elementary school students is a nutritious lunch provided by the school, which is like a box lunch. However, Martin always feels that the things on the plate are not so nutritious - white rice, a piece of tofu with sauce, a bowl of kelp miso soup with oil, and a small box of milk.

Although tofu and milk already have a lot of protein, looking at the light white or green plate, Martin refused the milk offered by his sensible adopted son and made a plate of braised pork for Ma Wu as a snack. (End of this chapter)
