1. Enter the appropriate numbers/formulas in the shaded (gray) cells. An asterisk (*) will appear to the right of an incorrect answer.
2. A formula begins with an equals sign (=) and can consist of any of the following elements:
Operators such as + (for addition), - (for subtraction), * (for multiplication), and / (for division).
Cell references, including cell addresses such as B52, as well as named cells and ranges
Values and text
Worksheet functions (such as SUM)
3. You can enter a formula into a cell manually (typing it in) or by pointing to the cells.
To enter a formula manually, follow these steps:
Move the cell pointer to the cell that you want to hold the formula.
Type an equals sign (=) to signal the fact that the cell contains a formula.
Type the formula, then press Enter.
4. Rounding: These templates have been formatted to round numbers to either the nearest whole number or the nearest cent. For example,
17.65 x 1.5=26.475. The template will display and hold 26.48, not 26.475. There is no need to use Excel's rounding function.
5. Remember to save your work. When saving your workbook, Excel overwrites the previous copy of your file. You can save your work at any time.
You can save the file to the current name, or you may want to keep multiple versions of your work by saving each successive version under a different name.
To save to the current name, you can select File, Save from the menu bar or click on the disk icon in the standard toolbar.
