Money

 Money is a medium of exchange that facilitates transactions in an economy. It serves as a unit of account, a store of value, and a standard of deferred payment. As a unit of account, money is used to measure the value of goods and services. As a store of value, money can be saved and used for future transactions. As a standard of deferred payment, money allows for transactions to occur in the future, such as when taking out a loan or buying on credit. The most common forms of money include currency, bank deposits, and digital currencies. The value of money is determined by supply and demand, and central banks regulate the money supply to maintain economic stability.
