Module 2 Accounting Equation
Importance of the Accounting Equation
 Business transactions affect the assets, liabilities, and proprietorship of the business.
 These effects can be expressed in the accounting equation:
                             ASSETS=EQUITIES
 Equity is the right, claim, or interest of a person over the assets of the business.
 Liability represents such claim in the assets of the business and proprietorship is
 the owner’s or owner’s interest in the business.
                                           LIABILITIES
               EQUITIES
                                          PROPRIETORSHIP
And since there are two sources of equities, one from the creditors (liabilities) and one
from the owner (proprietorship), then we can express the accounting as:
                    ASSET=LIABILITIES+PROPRIETORSHIP
