Lithuania is a country in Europe that has its own economy. An economy is like a big game where people buy and sell things to each other to make money. In Lithuania, people do many different jobs, like farming, making clothes, or building houses. They use the things they make or services they provide to trade with other people for money.
The government of Lithuania also plays a big role in the economy. They make rules to make sure people are being fair, and they collect taxes from people to pay for things like schools, hospitals, and roads. The government also tries to help businesses by giving them money or loans to start or grow their businesses.
Lithuania is also part of the European Union, which is like a big group of countries that work together. Being part of the European Union means that Lithuania can trade more easily with other countries and people can travel to Lithuania to do business.
All of these things together make up the economy of Lithuania. It's like a big puzzle where everyone plays a part in making sure things work well and people have what they need to live happy lives.
