money is a tool to exchange goods that will be purchased or goods in need by trading it with money.
The existence of money provides an easier alternative transaction than a more complex, inefficient, and less suitable barter used in modern economic systems because it requires people who have the same desire to exchange and also difficulties in determining value. Efficiency earned by using money will ultimately encourage trade and labor division which will then increase productivity and prosperity.
The exchange instrument can be any object that can be accepted by everyone in the community in the process of exchange of goods and services. In modern economics, money is defined as something available and generally accepted as a means of payment for the purchase of goods and services and other valuable property and for repayment of debt.
