                                     What is Accounting?

Accounting has been called «the language of 
business».Perhaps a better term is «the language of financial
decisions».The better you understand the language, the better you can manage
the financial aspects of living. Personal financial planning, investments, loans,
car payments, income taxes, and many other aspects of daily life are based on
accounting. A recent survey indicates that business managers believe it is more
important for college students to learn accounting that any other subject.
Other surveys show that persons trained in accounting and finance make in to
the top of their organizations in greater numbers than persons trained in any
other field. Indeed, accounting is an important subject.

Accounting is the system that measures business activities, processes that information
into reports and communicates these findings to decision makers. Financial
statements are the documents that report on are individual’s or an
organization’s business in monetary amounts.
