Final answer:
In a balance sheet, the little "x" refers to a cross-reference to footnotes or additional information, not a multiplication symbol, a placeholder, or a negative value indicator.
Step-by-step explanation:
The little "x" in a balance sheet typically refers to C) Cross-reference to footnotes or additional information. It does not represent a multiplication symbol, a placeholder for missing values, or denote a negative value. For example, the "T" in a T-account is a template used to showcase the assets on the left and liabilities plus net worth on the right, illustrating that assets will always equal liabilities plus net worth. An example of a bank's T-account would include financial instruments such as bank reserves, loans, and U.S. Treasury bonds as assets and deposits made by the customers as liabilities. The net worth reflects the difference between total assets and total liabilities and is critical in determining the financial health of a business.
