When you get out of university you'll understand what I'm about to say. The moment you graduated, after you got out, you'll realized that even your closest friends will have less and less time to hang out with you. And you, in turn, will have less time for them as well. If you learnt to be a future-oriented adult, you'll know that a full-time job comes almost right after your graduation, and you will start saving up for what comes next. But to answer your question, university is THE time to spend with your friends, to hang out and do wacky stuff like punch plates if you're into that kinda thing. The work itself will try to crush you, but don't hesitate to take some time off to be with who you care about, and also DON'T PULL ALL-NIGHTERS, those things are highly counter-intuitive.

a) /-293/ + /53/

= 293 + 53

= 246

b) /+1092/ + /-543/

= 1092 + 543

= 1635

c)12 + /-8/ + ( -15)

= 12 + 8 + (-15 )

= 20 + (-15 )

= 5

d)(-16) + (-14)

= -30

e)(-9)+(-8)+(-7)+...+7+8+9+10

=   [ (-9)+9] +[(-8)+8] + ...+ [(-1)+1] + 10

= 0+0+...+0+10

My name is Long and I’m a Vietnamese. I am twenty-four years old. I live in Ho Chi Minh city in the south of Vietnam. I have a big family with six people. I have two sisters and a brother. My sisters are older and my brother is younger than me. My father is a teacher at a secondary school. He has worked for 35 years in the field and he is my biggest role model in life. My mother is a housewife. She is nice and she is really good at cooking. I love my family so much. I’m a generous and easy-going person but when it comes to work I’m a competitive perfectionist. I’m also an optimistic and outgoing person so I have many friends and other social relationships. I enjoy reading, writing and doing math. I decided to become a Civil Engineer because I have always been fascinated by bridges, buildings, and skyscrapers. A degree in Civil Engineering enables me to achieve my goals and also gives me an opportunity to make a difference in the community.Five years from now, I want to become a project manager of a construction project. As a project manager, my primary goals are managing people, set budgets, and making decisions of all kinds. I also want to speak English fluently so I can work with people from different countries.

I have many hobbies, but I like reading most. Books are always a good friend to me. It is a good way to improve my vocabularies by exposing many new words. By reading, I get better at concentration because it requires me to focus on what I am reading for long periods. It also opens up the knowledge door for me. Reading books tell me about the world's history, let me see the structure of the brain, or bring me a story of Sherlock Holmes. I think reading is one of the most interesting indoors activity.

Some people say that they like living in the country, the others like living in the city. In my point of view, I prefer living in the countryside for a number of benefits. First of all , It is a quiet and peaceful place. There are a lot of plant species so the air and the food are fresh and clean. We can enjoy a healthy natural condition without worrying much about environmental pollution. We are free to admire the breathtaking landscapes such as huge meadows, peaceful hills or forests. We can also enjoy walking in the forest and picking mushrooms or hunting. Second, There aren't any huge blocks of flats, modern skyscrapers and bothersome traffic jams in the countryside so the air is not polluted. There is no water pollution, either. Moreover, living in the countryside is cheaper than it is in the city, so you can buy many hings at lower prices. The other positive side is the safety. In the rural area the crime rate is much lower. There aren't a lot of housebreaks of burglary and robbery. In the countryside people usually and keep eyes on neighbour's estates. They always react when something strange is happening. Finally, most of the villagers are friendly and hospitable. They are always willing to help each other. Moreover, people in the cities are very susceptible to stress because of pollution, the pressure of work, competitions, etc. In summary, Living in the countryside has many advantages because of fresh air, clean food, specially the people’s friendliness and hospitality.

My hobbies are listening to music, watching films and travelling. I love many kinds of music; especially, when I fill myself with the sorrow, I love the songs which can share my sadness. I also like watching some US sitcoms such as: How I met your mother, Once upon a time, Sabrina is the thing I enjoy in my leisure time. Besides, I extremely love travelling, exploring new places with plentiful cuisines and nature, especially walking along the beach in the dusk that make me comfortable and peaceful.
