Cách sử dụng
The expression "pay down" means to reduce the amount of something you owe, such as debt or a loan. It is often used when someone has taken out a loan or borrowed money and then makes payments over time to lower the amount they owe. For example, if you have a credit card with a balance of $500 and you make a payment of $100, you would have paid down your debt by $100. This expression is commonly used in personal finance and banking.
