What financial statements measure a firm’s revenues, expenses, profits, and cash flows?

"An income statement is a financial statement that summarizes a firm’s revenues and expenses and shows its total profit or loss over a period of time. Net loss is the amount obtained by subtracting all of a firm’s expenses from its revenues, when the expenses are more than the revenues. Net profit (net income) is the amount obtained by subtracting all of a firm’s expenses from its revenues, when the revenues are more than the expenses. Net sales are the amount left after deducting sales discounts and returns and allowances from gross sales. Revenues are the dollar amount of a firm’s sales plus any other income it received from sources such as interest, dividends, and rents. A statement of cash flows is a financial statement that provides a summary of the money flowing into and out of a firm during a certain period, typically one year."
