As humans have evolved, so has the concept of trade and money. We determined that a barter economy, or a moneyless economy that relied on trade, would work for a simple society, but it could not work for a complex society. Without money, trade is not always easy or mutually beneficial. The use of money has made life and trade much easier on a country and its population. Money functions as a medium of exchange, a measure of value, and a store of value. Money is portable, durable, easily divisible, and limited in availability. Money has evolved so much over the last two hundred years that it has moved from gold and silver coins to paper currency, to checks, debit cards, and credit cards. )=) brainly me
