Finance refers to the management, creation, and study of money, investments, and other financial instruments. It encompasses a wide range of activities including borrowing, lending, saving, investing, and budgeting. Finance is divided into three main subcategories: personal finance, which deals with individual or household financial decisions; corporate finance, which focuses on the financial operations and capital structure of businesses; and public finance, which involves the management of funds and expenditures by government entities. Finance plays a critical role in the economy by facilitating the allocation of resources, assessing risks, and enabling transactions, ultimately aiding in economic growth and stability.
