The balance of trade involves the exchange of goods and services between countries.
Goods are physical products that can be traded, such as cars, clothes, and food. Services, on the other hand, are intangible products that cannot be touched, such as transportation, banking, and tourism.
When countries engage in trade, they can export goods and services they produce and import goods and services that they need. The balance of trade is the difference between the total value of a country's exports and the total value of its imports.
If a country exports more than it imports, it has a trade surplus, which means it is earning more from trade than it is spending on imports. If a country imports more than it exports, it has a trade deficit, which means it is spending more on imports than it is earning from exports.
