Final answer:
The difference between the value of exports and imports of a country is called the trade balance.
Step-by-step explanation:
The difference between the value of exports of a country and the value of its imports over a given period is called the trade balance. It is calculated by subtracting the value of imports from the value of exports. If a country's exports are larger than its imports, it has a trade surplus. On the other hand, if a country's imports are larger than its exports, it has a trade deficit.
