\(-\frac{1123}{123}+123-\frac{1234}{3456}\)

\(=\frac{14006}{123}-\frac{1234}{3456}\)

\(=113,5128585\)

113,5128585 k tui nha

B) (-11)+350+16+(-350 )

= - 11 + 350 + 16 - 350 )

= ( - 11 + 16 ) + ( 350 - 350 )

= 5 + 0 =5

C) (-10)+23+(-20)+30

= - 10 + 23 - 20 + 30

= ( - 10 - 20 + 30 ) + 23

= - 30 + 30 + 23

= 0 + 23 = 23

D) (456-123)+123

= 456 - 123 + 123 

= 456 

E) (-102)-(345-102)

= - 102 - 345 + 102

= ( - 102 + 102 ) - 345

= 0 - 345

= - 345

F) (12-34)-(34-8)

=  12 - 34  - 34 - 8

= (12 - 8 ) + ( -34 - 34 )

= 4 - 68 

= 64

 G) (12+34-56)-(12-56)

= 12 + 34 - 56 - 12 +56

= ( 12 - 12 ) + ( -56 + 56 ) + 34

= 0 + 0 + 34

= 34

My favourite subject in high school is English. I not only want to become fluent in foreign language but also desire to deeply understand the beauty of this language. In my opinion, English is one of the most powerful tools that exists nowadays to communicate to other people. It makes easier to make friends around the world. By using english, we can explore the world in a deeper way.

Thanks to this language, I can understand more about different cultures. I am the kind of person who love traveling. Therefore, it’s essential to master in English if you want to communicate to the local people.In addition, you won’t feel lost in the middle of a city because you can ask the natives for help. It was such an amazing method of communication when I travelled in Japan, French or Korea without knowing the local languages.

Furthermore, I believe that English helps a lot to get access to the latest information about scientific topics such as Economics, which by the way was my major at university. If you want to be at the forefront in your professional field, nothing is better than reading the different arles. Whilst, most of them are written in English.

In conclusion, I think that there are many reasons to learn English because of it’s benefits. If you really fall in love with English, you will never want to give up it for any reasons.

Ta có : G = 123123 . 456 

    = 123.1001.456

H = 456456 . 123

    = 456.1001.123

Vậy G = H
