How does money help people trade with different people?
Imagine a grower has apples and wants a loaf of bread. With direct barter, the grower needs to find someone who has bread and wants apples at the same time. Those wishes may not match.

If people accept the same money, the grower can sell apples to one person and later buy bread from someone else. The money connects two trades that do not need to happen with the same partner.
Money works because people expect it to be useful in later exchanges. It does not grow the apples or bake the bread. The goods still need people and materials, while money helps organize how people exchange them.
