# Excel Course: Comparison Operators

In the previous example, we wanted to know whether the value was "greater than", using the `>`

sign. These are the other operators that can be used in its place:

= | is equal to |

<> | is different than |

< | is less than |

<= | is less than or equal to |

> | is greater than |

>= | is greater than or equal to |

As well as:

AND | =AND(formula_1,formula_2,formula_3) All the conditions must be true |

OR | =OR(formula_1,formula_2,formula_3) At least one of the conditions must be true |

Here is an example of the IF function using "AND":
