Monetary system

A monetary system is a way of managing money. It is used by governments, businesses and people to buy, sell, save and invest. Money can come in many different forms, like coins and bills, or as numbers in a bank account. The way money works depends on the type of monetary system a country or company uses. For example, some countries use a system that measures the value of money by how much gold it is worth. Other countries use paper money that can be exchanged for other kinds of money, or for goods and services. In all systems, money is used to buy things and to save for the future.
