About 4

I will associate the role "Suu anko" of Mahjong from 4.

Suu anko is called "Four concealed triplets" in English.

Four Suripea and one of two pair is called to make in the menzen.

It is so difficult and expecting high score.

Suu anko is called Yakuman. 

Yakuman is the strongest role in Mahjong.

Person who made the Suanko you will win most on the spot.

It is also the longing of people to the mah-jong.

 

 

Now, let us look one from a mathematical point of view.
4 four to use and you can make a number of 0-100.
Let's seek another solution.

About 3

　For 3 of the first to come up, it is "Ｓｅｋａi no Nabeatu". He will be the fool when you say the number that take the multiples of 3 or include 3.He became very famous in 2008 by this joke.Please take a look at the video below so very interesting.(He becomes fool when he say the number that take the multiples of 3 or include 3 .And he will comfortably when he say a multiple of 8 in this video.)

 Now, let us look one from a mathematical point of view.

  
I will associate the triangle Speaking 3.The most famous theorem in the triangle, would Pythagorean theorem.

"In mathematics, the Pythagorean theorem — is a relation the three sides of a right triangle (right-angled triangle). In terms of areas, it states:

In any right-angled triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle)."

 The approach starts with the same four triangles, except that, this time, they combine to form a square with the side ( a + b ) and a hole with the side c .

  We can compute the area of the big square in two ways. Thus

 

 

simplifying which we get the needed identity.

About 2

I write trivia about 2 

 Jupiter is smaller each year 2cm.

 

Now, let us look one from a mathematical point of view.

2 is well known and is the smallest prime number.

In addition, it is only one prime without the spelling e.

 

２：two

３：three

5：five
7：seven
11：eleven
13:thirteen
17:seventeen

...

In addition to　"Euler's polyhedron formula"
When it is three-dimensional polyhedron
(Number of Faces)−(Number of Edges)＋(Number of Vertices)=２

Writing a 1-Paragraph Opinion Essay

The best foreign language learning method, I think that memorize the words.

First reason is easy to reading.

Second reason is easy to continue.

But some people think that most important is grammar.

However Even without knowing the grammar, it is possible to speak a word.
