Excel Spreadsheet Formula Notes
GENERAL NOTES:
Start the formula with an = sign.
The function names, such as SUM and the cell location letters, such as A1
may be in capital or lower case letters.
To display and print the formulas instead of the values in a spreadsheet:
1. Click on the Formula tab of the Office Ribbon.
2. Click on the down triangle next to Formula Auditing.
3. Click on Show Formulas.
The spreadsheet with formulas instead of values will be shown on the screen
and may be printed that way.
FORMULA ERRORS:
If a formula is typed without beginning with the equal (=), plus (+), or
minus (-) sign it will be ordinary text and it will not be recognized as a
formula
Formula errors generate a message referring to the type of error.
