1. Start by defining what money is in the context of macroeconomics. Consider what characteristics make something 'money' rather than just a valuable item.

2. List and briefly describe each of the main functions of money. For each function, think about how it helps facilitate economic activity.

3. Consider examples for each function to solidify your understanding (e.g., how money acts as a medium of exchange in daily transactions).
