El Mundo Del Comercio (the World Of Trade)
Resumen del Libro
Before there was money, people bartered, or traded, goods and services to get the things they needed and wanted. Now, we use money in the form of bills and coins to buy goods and services. People have markets all around the world where they sell their goods. One special type of market is a stock market where you can buy shares of stock in a company and own a small or big part of that company. Trade is everywhere-you can even trade part of your card collection with a friend.
