Cách sử dụng
The word billion is used to represent a very large number. It means one thousand million, which is written as 1,000,000,000. It is often used when talking about things on a global or national scale, such as the population of a country or the amount of money in a budget. It is important to remember that in American English, a billion is 1,000,000,000, whereas in British English, it used to be 1,000,000,000,000 but has now been standardized to mean 1,000,000,000 as well. When using the word billion, it is best to provide context and avoid confusion by specifying which English variation is being used.
