Cách sử dụng
Zero is a number that stands for nothing or no amount. We can use this word when we want to express that there is nothing or no amount of something. For example, if someone asks how many apples you have in your basket and you have none, you can say "I have zero apples." We also use zero when referring to temperature, for example, "It is zero degrees Celsius outside." Remember, zero means nothing or no amount!
