An economy is a system of exchange of things of value. To better understand how the economy works, it can be broken up into three sections. These are:
- the Primary sector: which covers raw products from farming, fishing, and mining, and so on.
- the Secondary sector: which covers manufacturing of goods
- the Tertiary sector: covers a range of services, provided to people and companies.
The word "economy" comes from the Greek word οἰκονόμος, meaning "person who manages the house." The largest economy in the Americas is the U.S., in Africa it is Nigeria, in Europe it is Germany and in Asia it is China.
