Cách sử dụng
The expression "down to the last, smallest, final, etc. something" is used when you want to emphasize that you have used or completed all of something, even if it was just a small amount left. This phrase is commonly used in situations where every little bit counts or in situations where something needs to be finished completely. For example, "I drank all the water in the bottle down to the last drop," or "I cleaned the house down to the smallest detail." Essentially, it means that you have completed something thoroughly and there is nothing left to do.
