1)
(-1/4 + 5/8 ) + 2/3
=3/8 + 2/3
=25/24
2)
(1/-4 + 5/ 8 ) + -3/8
=1/-4 + 5/8 + -3/8
=1/-4 + 2/8
= -2/8 + 2/8
=0

B sẽ nhỏ hơn
=> Vì ( -1 / 243 ) ^ 6 sẽ là số nguyên âm
=> Mà ( 1/80 ) ^ 7 sẽ là số nguyên dương
=> A > B

1 + 2 -3-4 + 5 + 6-7-8+...+2017+2018
= 1 + (2-3-4+5) + (6-7-8+9) + ...+ (2014-2015-2016+2017) + 2018
= 1 + 0+0+...+0+2018
=2 019

B=7(5/2×7+4/7×11+3/11×14+1/14×15+13/15×28)
B=7(1/2-1/7+1/7-1/11+1/11-1/14+1/14-1/15+1/15-1/28)
B=7(1/2-1/28)
B=7×13/28
B=13/4

My best friend classmate is Nga. The first reason why I her most is her nice appearance. She has long black hair and beautiful eyes. She is tall and thin enough to paripate in VN nexttop model. Not only does she have a pretty appearance but she also has good characteriss. When I feel sad, nervous or stressful, she is always by my side and encourage me to overcome difficult challenges in my life. I'M so grateful for it. Moreover, she once said that:" If oneday you feel crying, call me..I don't promise that i will make you laugh..but i can cry with you" In addition to that, we have unforgetable experience. In 1997, I was drowning when she appeared and secured me from the Death and since then, we has become closed fiends. We share a lot of things such as dreas, jobs, hobbies,.. I strongly believe that our relationship is lasting forever.

The person that I trust the most is my best friend, Nha. She is 18 years old. She is also my English private tutor who has been teaching me for 3 years.
She is very pretty with a lovely round face and beautiful dark brown eyes. Although she is not so tall, her black hair is very long and silky. Her favorite clothes are jeans, T-shirts and sneakers for their comfort. At first, she appeared serious but later she showed her humorous side. She always makes me laugh all the times when we see each other. She is not only good at English but she also plays piano exceptionally well. She can even compose songs. Furthermore, conscientiousness is the most beautiful personality of her. She makes people feel pleasant in her caring and understanding quality.
She is both well-qualified teacher and a precious friend to me. I hope our relationship can last long and remain stable
