1) The document provides instructions on getting started with Excel, including how to navigate worksheets, select and enter data, format cells, and use basic formulas. It covers functions like IF, AND, OR and NOT.
2) Formatting cells allows you to change how data is displayed, such as displaying numbers as currency or dates. You can also create custom formats. Absolute cell references lock the cell reference so it does not change when a formula is copied.
3) Names can be assigned to cells or ranges to make formulas and references more readable. The GOTO feature and names allow quickly navigating to cells. Names are also useful in formulas in place of cell references.
