A *formula *is an equation to performs calculations. It is like using a calculator. Using *formulas *in Excel you can add, subtract, multiply, and divide, and much more…

*Called reference* in Excel is the ability to calculate using the cell address to represent the value of the cell.

Let’s make a simple *formula*! Excel uses standard operator for the calculation such as ( +, -, *, /, ^ ), and always ( = ) at the beginning of the equations.

How to: | operator | formula | ||

Add | + | =3+3 | = | 6 |

Subtract | – | =3-3 | = | 0 |

Multiply | * | =3*3 | = | 9 |

Divide | / | =3/3 | = | 1 |

Exponent | ^ | =3^3 | = | 27 |
