In a spreadsheet there are three basic types of data that can be entered.
*ALL formulas MUST begin with an equal sign (=).
- labels - (text with no numerical value)
- constants - (just a number -- constant value)
- formulas* - (a mathematical equation used to calculate)
| data types | examples | descriptions |
| LABEL | Name or Wage or Days | anything that is just text |
| CONSTANT | 5 or 3.75 or -7.4 | any number |
| FORMULA | =5+3 or = 8*5+3 | math equation |
*ALL formulas MUST begin with an equal sign (=).
