There is a small playground in our school-compound. During the tiffin hour, we play there. We play volley-ball and badminton. There are two swings on the side, We swing there merrily. We have a good library on the ground floor of the school-building. Our librarian is…………... She helps us in selecting good books. We take books on loan to read. The students of our school are gentle and disciplined. There is not much noise in our school. Our Principal is very strict. But he is also kind to all. I am happy as a student of my school. I love my school, my classmates, and my teachers. My school is my second home.

I study in Hung Dao School which is one of the best schools of QuanG Ninh. It has a stone building. It has all facilities a good school should have-well furnished classrooms, laboratories, library and playground.

As we enter the school, there is a playground to our left and a small garden to our right. When we enter the building, the Principal’s room and the office room are to the left and the staff room to the right side. These are well furnished. There are thirty four classrooms. Our labs are well equipped. Our library has books almost on all subjects. Our Librarian is also very helpful.

Our school, all schools, has a prescribed uniform. We have to wear white or cream cotton shirts, light-blue trousers, black shoes and white socks. Girls have to wear white blouses and light-blue skirts in primary and middle classes and white shirts and light-grey skirts in higher classes. They have to tie white ribbon also.

In our school special attention is paid to behavior, cleanliness and punctuality. The most well behaved, neat and punctual student is awarded a prize at the Annual Day function.

Our Principle is a strict disciplinarian. He takes the help of P. T. Teachers too. If any one violates the rules, and is not in uniform, or makes mischief, he gets punished. But he is fair and loving. He tries to find out the reason and guides us.

Our teachers are also quite strict. They teach us with great care, check our note-books, help us when we need but if we are inattentive and don’t work properly, then we are punished.

I my school very much and I am proud that I belong to it. I shall never forget it.

a) Chữ số 2 ở hàng đơn vị là:

            (2012 - 2) : 10 + 1 = 202 (số)

    Chữ số 2 ở hàng chục là: 

             [(1920 - 20) : 100 + 1] x 10 = 200 (số)

   Chữ số 2 ở hàng trăm là:

             [(1200 - 200) : 1000 + 1] x 100 = 200 (số)

   Chữ số 2 ở hàng nghìn là:

             2016 - 2000 + 1 = 17 (số)

Từ 1 -> 2016 có số các số 2 là:

            202 + 200 + 200 + 17 = 619 (số)

                                                Đáp số: 619 số

Cho mình hỏi là tại sao lại lấy 2012 mà ko lấy 2016🤡

Chữ số 2 ở hàng đơn vị: (2012 - 2) : 10 + 1 = 202 (số)
Chữ số 2 ở hàng chục: Cứ 100 số có 10 số có chữ số 2. Suy ra: Chữ số 2 ở hàng chục là: [(1920 - 20) : 100 + 1] x 10 = 200 (số)
Chữ số 2 ở hàng trăm: Cứ 1000 số có 100 số có chữ số 2. Suy ra: Chữ số 2 ở hàng trăm là: Có [(1200 - 200) : 1000 +1] x 100 = 200 (số)
Chữ số 2 ở hàng nghìn: 2016 - 2000 + 1 = 17 (số)
Từ 1 đến 2016 có số các chữ số 2 là: 202 + 200 + 200 + 17 = 619 (số)

48 mk lm rồi,chắc 100% lun

[2016-4-2]:2+1=1006

1006 so nha ban k mk cai 

mk vua lam xong bai nay

Ta có: x < y < 0 

=> | x |  = - x  và | y | = -y 

Nên |x | - | y | = -x - ( -y )  = -x + y = -(x - y)

Vì | x | - | y | = 100 

suy ra - ( x - y ) = 100 hay x - y = -100

x<y<0=>|x|-|y|

=-x -(-y)=x-y=100

=x-y=-100
