State two functions of money.

Money has four main functions: 1. **Medium of exchange:** It is widely accepted as a form of payment for goods and services, eliminating the need for a barter system. 2. **Store of value:** It can be saved and used for future purchases, holding its value over time (assuming low inflation). 3. **Unit of account:** It provides a common measure of the value of goods and services, allowing for easy comparison. 4. **Standard of deferred payment:** It can be used to settle debts in the future.
