Explain 3 aids to trade

Here are three aids to trade:

1. Money: Money serves as a medium of exchange, eliminating the need for barter. It is a universally accepted store of value and a unit of account, making transactions simpler and more efficient.

2. Transportation: Efficient transportation systems (roads, railways, shipping, air cargo) are crucial for moving goods from producers to consumers. They reduce costs and delivery times, expanding market reach.

3. Communication: Modern communication technologies (internet, phones) facilitate the exchange of information about prices, availability, and demand. This allows businesses to coordinate activities, find new markets, and manage supply chains effectively.
