For example: A bike dealership set a goal of selling a certain number of bikes each week. The table shows how their weekly sales compared to the goal.

Week | Sales Compared to Goal |

1 | -2 |

2 | 1 |

3 | 3 |

4 | -1 |

We need to find, in which week did the dealership sell the fewest and most bikes?

Solution:

To solve this problem we need to compare the values -2, 1, 3 and -1. From these values, -2 is the smallest and 3 is the largest number.

-2 corresponds to the first week, therefore in the first week, the dealership sells the fewest bikes.

3 corresponds to the third week, therefore in the third week, the dealership sells the most bikes.
