Magical use of numbers

(0-9 on both sides)

Qi: Students, do you know who we are? (number)

1: Yes, we are numbers. Numbers are widely used in people's lives and have created many picturesque chapters.

(on the decimal point)

Point: Have me! Although I am not a number, I am also a member of the number!

Qi: Yes, come here!

Point: Where do I stand?

Qi (Zheng) me, me.

Point: (Hold out your chest) Look, how popular I am, where I stand, and any number may change.

2: Yes, there is a close relationship between our figures. We influence each other and depend on each other.

3: That's right. Come on (called 1, 4 and dot), we stand together. Look, how much is this?

Qi: Isn't this 3. 14?

3. Yes, in mathematics, it is the approximate value of pi. As early as more than two thousand years ago, China had the idea of "getting a lesson on Wednesday", which is what people call pi ∏ today. However, this concept didn't appear in western countries until17th century, which was 1000 years late!

(Everyone nods and thumbs up)

6. In fact, everyone deals with our figures every day. An illiterate person can live completely, and an illiterate person can hardly live. Come on (called 0.6 18), let's make a number for everyone to see. (composition is 0.6 18)

(everyone looks)

9: I see, your composition of 0.6 18 is the golden section in mathematics.

7. I also know that the golden section is a matter of proportion. If people meet this ratio in life, they will look pleasing to the eye and comfortable. For example, a person's navel is the golden section of a person's length. If you divide a person's height by the length from the head to the navel, it is close to 0.6 18, which is generally a beautiful golden figure. The knee is the golden section below the navel. There are many examples of this.

5. Our numbers have profound beauty content, and numbers are associated with some beautiful things, which will give people beautiful enjoyment.

1: Yes, what describes us 1 is "single-minded" and "smooth sailing". How beautiful.

2. "The Second Plum Blossom" and "Double Happiness"

3. "Three Yang Kaitai" and "Think twice before you act"

4. "Getting rich in four seasons" and "extending in all directions"

5. "Correct facial features" and "Five Dynasties Prosperity"

6. "Six Great Shun" and "Six Quiet Roots"

7. "Seven-Step Talent" and "Eloquence"

8. "extending in all directions" and "extending in all directions"

9. "Nine Heavenly Worlds" and "Nine Nine in One"

0: (scratching his head) Why can't I remember anything about me! I just think that many rules are "except 0".

1: Who said we stood together at 10? It was perfect.

0: Right, right.

8. There are many beautiful sentences with numbers in China's poems. For example, "There are three thousands of feet flying in the sky, and it is suspected that the Milky Way has set for nine days", including you two. (Articles 3 and 9)

3. Also, Yue Fei's "Thirty Laws, Dust and Earth, Eight Thousand Miles of Clouds and Moon" is so strong!

4: There are more! Do you know a poem with many numbers written by Zheng Banqiao?

Qi: I know.

One, two, three or four, five, six, seven, eight and ninety.

1 2 34 qishuo 5 6 7 8 9 1 and 0 qishuo

Qi: Thousands of pieces, countless pieces, always disappear when flying into plum blossoms.

Viewpoint: There is too much mathematics in life. It depends on whether you have observed it carefully.
