2) Operating activities relate to core business operations like production and sales. Investing activities involve the purchase and sale of long-term assets. Financing activities include activities related to debt and equity.
3) There are two methods for calculating cash flow from operations - the direct method lists actual cash flows, while the indirect method reconciles net income to cash flows by adjusting for accruals and non-cash items.
