Đức à đây là kiến thức cơ bản mà
1-2+3-4+5-6+...+99-100+101
= (1+3+5+...+101) - (2+4+6+...+100)
tu 1 den 101 co : (101-1):2+1=51
1+..+101 = (1+101)x 51:2= 2601
tu 2 den 100 co : (100-2);2+1=50
2+...+100 = (100 +2) x 50:2=2550
=> A= 2601-2550=51

Hi everyone, my name is Phuong. I will introduce my family to you. Our family has 4 people including my father, my mother, my younger brother and me. My father is an engineer at a construction site near my home. My father is very busy. He usually had to stand outside all day. So he has a tanned skin. However, one day he still spends time playing with me. My mother is a good housewife. Every day I can eat delicious dishes that I cook. Mother takes care of her family very well. Before I go to bed, my mother usually reads me a story. My brother is 10 years old this year. Very good boy. I often play with him in my free time so my mom can do other things. I love my family very much.
