Integer Rules Review

Adding Integers:

|Examples: |Rule: |

|4 + -9 = | |

|-4 + 9 = | |

|-3 + 2 = | |

|3 + -2 = | |

Subtracting Integers:

|Examples: |Rule: |

|4- (-9) = | |

| | |

|-4 – 9 = | |

| | |

|-3 – 2 = | |

| | |

|3 – (-2) = | |

Multiplying Integers:

|Examples: |Rule: |

|2 x -3 = | |

| | |

|-2 x 3 = | |

| | |

|4 x 3 = | |

| | |

|-2 x -5 = | |

Dividing Integers:

|Examples: |Rule: |

|6 ÷ -3 = | |

| | |

|-6 ÷ 3 = | |

| | |

|-4 ÷ -2 = | |

| | |

|10 ÷ 2 = | |

Practice Problems:

1. -6 – 7 =

2. 3 · -6 =

3. -8 · -3 =

4. 15 – (-9) =

5. -4(5) =

6. -56 ÷ 7 =

7. 120 =
