Cách sử dụng
The word 'subset' is used when you have a group of things and you want to talk about a smaller group that is part of the bigger group. For example, if you have a collection of fruits like bananas, apples, and oranges, you could say that bananas and apples are a subset of the bigger group of fruits. It's also used in math and science when talking about sets of numbers or data. For instance, if you have a set of even numbers like 2, 4, 6, and 8, you could say that 2 and 8 are a subset of the set of even numbers. Overall, 'subset' is a word used to describe a smaller group that is part of a bigger group, whether you're talking about fruits, numbers or other kinds of things.
