Financial accounting records and reports what a business owns, owes and earns. Everything rests on the accounting equation, Assets = Liabilities + Equity, and on double-entry bookkeeping, where every transaction affects at least two accounts so the equation always balances.
The course builds from journal entries to the three main statements. The income statement shows revenue and expenses over a period, the balance sheet shows the position at one date, and the cash flow statement explains how cash changed. Ratios such as gross margin and the current ratio turn those statements into comparisons between companies.
Accounting is the language of business. Managers, investors, lenders and small-business owners use these statements to judge profitability and risk, and anyone running a side business or reading a company report benefits from understanding them.
