A formula is simply a mathematical expression that uses numbers, cell references or both. A formula can use only numbers but in Excel most formulas you build will contain at least some references to others cells containing some numerical values.

For instance calculating the percentage of a value or converting a figure to another currency requires a formula. One of the reasons formulas are so potent is because if any cell referenced by the formula change, the result of formula updates instantly.

There are two easy steps you must follow every time you need to create a formula.

· Move to cell where you want result to be.

· Hit the equal (=) character.

The result depends on what the formulas needs to do.
