## Explanation

In this example the XOR function contains two expressions, one to test for an "x" in column C, and one to test for an "x" in column D.

```
C5="x" // TRUE if coffee is "x"
D5="x" // TRUE if tea is "x"
```

With two logical criteria, XOR has a particular behavior, summarized in the table below:

Coffee | Tea | Result |
---|---|---|

TRUE | FALSE | TRUE |

FALSE | TRUE | TRUE |

TRUE | TRUE | FALSE |

FALSE | FALSE | FALSE |

At each row in column E, XOR evaluates values in column C and D and returns a TRUE or FALSE result. This behavior is sometimes referred to as "exclusive OR", meaning only one result can be true.

*Note: with more than two criteria, XOR behavior changes, as explained on the XOR function page.*
