Long ago, people traded things like apples for tools. But that was hard, you had to find someone who wanted what you had and had what you needed! Then came coins, which were easy to carry and use anywhere. Later, paper money made trading even easier. It all started with a simple idea: making trade simpler.
Examples
- A farmer trades wheat for a pot full of beans
- A merchant carries paper money instead of heavy gold coins
