Chapter 218 With such profound mathematical knowledge, everyone knows it!?
"It's for you, open it and take a look." Su Yu said with a smile.
Ying Yinman this girl, from now on.
Except that she often hides outside the terrace at night to watch some pictures she shouldn't watch, the rest of the place seems to be a little undesired.
Now that she has shown a strong interest in mathematics.
Su Yu will naturally be satisfied.
Ying Yinman eagerly opened the first book on the top.
Primary 1 Mathematics, Volume 1...
Um?
what is this?
Ying Yinman's expression became strange.
It's... too simple, isn't it?
1+1=?
2+3=?
3-1=?
Are you sure this is for her?
Sir, this is... self-doubt of your own ability?
"Six two three" is difficult, I just didn't do well on that question.
The gentleman just praised himself, just because of face, so embarrassed to say it directly?
So I gave myself these books to consolidate my foundation?
Ying Yinman felt a little ashamed.
His face was ashamed like a cloud of fire.
However, she still likes this book, presumably it should be a book from the fairy world.
Not only was the color so rich, it also depicted some species she had never heard of.
A little white rabbit who can push a cart.
A lamb who makes friends.
Kittens that can count.
The animals of the fairyland are so amazing...
Seeing Ying Yinman looking at the well-developed animal patterns on the first grade math book, Su Yu was a little confused.
What's the matter with this girl?
Why are you still fascinated by the simple strokes?
"Yin Man?" Su Yu couldn't help crying.
"what!?"
Ying Yinman was stunned for a moment, and suddenly recovered from the fairy world with a little white rabbit on a cart that he had imagined in his mind.
Seeing Su Yu's puzzled eyes, Ying Yinman reacted.
I'm still flipping through the books here, how can I get distracted.
So she quickly picked up the second book.
The second volume of the first grade of elementary school... It's still very simple.
Second grade book 1... oh, the numbers for multiplication and division are a bit big.
Second grade book 2... eh? There are multiplication, division and addition and subtraction. Which one should be calculated first? Why should it be calculated first?
3rd Grade Book 1... Multiplication and division of tens of thousands? What are fractions? Graphs? Possibilities?
Ying Yinman's face became a little solemn.
The content of this book is not as simple as before.
At least something has appeared that she hadn't been exposed to before.
Like some vertical multiplication and division.
Although she had never come into contact with these things, she was clear just by taking a quick glance.
Use this method to calculate multiplication and division with Arabic numerals.
It may be much more clever and simple than the method that Daqin used today.
Ying Yinman put down the mathematics book in the first volume of the third grade, and took out a few more books at the back.
She has found it now.
It turned out that her husband looked down on her and gave her a set of very simple books.
But these books are from the shallower to the deeper and more and more difficult.
She wants to see.
Among the immortal books, what will be more difficult later.
However, as soon as he opened the book, Ying Yinman found out.
There are more and more things that I can't understand or even understand here...
Factors, common factors, common multiples, prime numbers, composite numbers, true fractions, false fractions,
Proportion, reduction, common division, numerator, denominator, algebra, negative numbers...
Area of a circle, volume of a cylinder, volume of a cone, equations…
"Snapped……
Ying Yinman was shocked and closed the second volume of the sixth grade mathematics book in her hand.
She hadn't thought of it at all.
It turns out that arithmetic can also derive such profound knowledge.
There are things in here that she has thought about and doubts.
All are now found in these twelve books.
"Sir, there should be a lot of people who know these books in your place? 35 Win Yin Man asked subconsciously.
Being able to record such profound arithmetic knowledge, these books must be very famous even in Immortal Realm.
Su Yu nodded as a matter of course: "Well, this is something everyone has to learn..
Hearing Su Yu's words, Ying Yinman looked at the cover of the book again.
Below the word "big math" above, a small seal is being used to indicate the "level" of the book.
1st grade, 2nd grade, 3rd grade...
Ying Yinman estimated in her heart that she was almost at the level of the third grade.
Mr. said that his talent is very good.
I don't know how it compares to the people in the fairyland.
Thinking of this, Ying Yinman looked at Su Yu and asked, "Sir, are these six grades and twelve volumes of books that all of you know?
She asked politely.
In Ying Yinman's guess, if you study carefully.
These twelve math books for the sixth grade should be able to master within a few years.
If it is said that no one in the immortal world can comprehend all the twelve volumes of mathematics.
It shows that her talent, even in the fairyland where her husband was before, is not too bad, so she is very satisfied.
Hearing Ying Yinman's question, Su Yu was slightly taken aback.
They thought that Ying Yinman would ask this question.
"You said these twelve books? Under normal circumstances, everyone should know them, right?"
hiss……
Ying Yinman's heart trembled.
How can such a complex mathematical problem be mastered by everyone?
Sure enough, it is the legendary fairyland.
Everyone is so smart.
Then 5.0 she hurriedly asked again: "What age are the people in that Mr.'s place, who studied these books thoroughly?
Su Yu thought for a moment.
Generally, children go to school at the age of six or seven, and primary school for six years, which is about eleven or twelve years old.
So he replied: "These things are relatively basic, and generally children around twelve years old should be able to master them thoroughly.
"Ten... Eleven or twelve years old!?"
ps: I think I understand that in most areas it is the sixth year of primary school and the third year of middle school.
Therefore, the textbooks used in the book are six-year textbooks (deliberately flipped through the catalogue found by Baidu Library...)
It seems that in some areas there are five years of primary school and four years of junior high school.
Dear readers, do you have this kind of nine-year compulsory education?
