what do you mean by double entry system of accounting
Double-entry bookkeeping system Double-entry bookkeeping, in accounting, is a system of bookkeeping so named because every entry to an account requires a corresponding and opposite entry to a different account. For instance, recording earnings of $100 would require making two entries: a debit entry of $100 to an account named "Cash" and a credit entry of $100 to an account named "Revenue."[further explanation needed]
Cash flow statement In financial accounting, a cash flow statement, also known as statement of cash flows,[1] is a financial statement that shows how changes in balance sheet accounts and income affect cash and cash equivalents, and breaks the analysis down to operating, investing and financing activities. Essentially, the cash flow statement is concerned with the flow of cash in and out of the business. The statement captures both the current operating results and the accompanying changes in the balance sheet.[1] As an analytical tool, the statement of cash flows is useful in determining the short-term viability of a company, particularly its ability to pay bills. International Accounting Standard 7 (IAS 7), is the International Accounting Standard that deals with cash flow statements.
