Why do countries need to have a system for exchanging currency with other nations? 1. to have a uniform value of currency so they can identify what the value of goods are

2. to know which countries' currency has the greatest value so they can buy goods at the lowest cost

3. to know the value of their money compared to the value of other countries' money so they can trade goods

4. to have an international bank that converts the money of each country so countries can buy and sell goods
