I was doing vacuum for my room. After I have finised the work of vacuuming, I noticed that there are so many dusts in my room. This is because the floor is covered with carpet. Thus, the carpet can stick the dusts in the air easily
I am doing my excel. But, I feel confused about the result that I have done. Obviously, I have big doubts about it. Finally, I decide to make an appointment with the lecturer in order to solve my doubts.
