Cách sử dụng
When we say "use up," it means we have used all of something, and none of it is left. For example, if you use up all the toothpaste, it means there is no toothpaste left in the tube. We often use this expression when we talk about finishing something or when we don't have any of something left. Another example could be "I used up all my money shopping yesterday, so I can't go out to eat today."
