Subtracting Integers on a Number Line
Subtract: 4 - 7
Rewrite as addition: 4 + (_
_)
* Start at 0.
* Plot 4 by moving 4 units to the right.
* Add -7 by moving 7 units to the left.

4 - 7 = _

Subtracting Integers on a Number Line
Subtract: -2 -3
Rewrite as addition: -2 + (
• Start at 0.
_)
* Plot -2 by moving 2 units to the left.
* Add -3 by moving 3 units to the left.

-2 - 3 =___

Subtract: -3 - 3
Rewrite as addition: -3 + (
_)
* Start at 0.
* Plot -3 by moving 3 units to the left.
* Add -3 by moving 3 units to the left.

-3 - 3 =____
The distance from 0 to -6 is 6 units.
So the distance =___

Subtract: 5 - (-2)
Rewrite as addition: 5 +
* Start at 0.
* Plot 5 by moving 5 units to the right.
* Add 2 by moving 2 units to the right.

5 - (-2) = _
The distance from 0 to 7 is 7 units.

Let's fill in the blanks for each subtraction problem:

  1. Subtracting Integers on a Number Line

    • Subtract: 4 - 7
    • Rewrite as addition: 4 + (-7)
    • Start at 0.
    • Plot 4 by moving 4 units to the right.
    • Add -7 by moving 7 units to the left.

    4 - 7 = -3

  2. Subtracting Integers on a Number Line

    • Subtract: -2 - 3
    • Rewrite as addition: -2 + (-3)
    • Start at 0.
    • Plot -2 by moving 2 units to the left.
    • Add -3 by moving 3 units to the left.

    -2 - 3 = -5

  3. Subtracting Integers on a Number Line

    • Subtract: -3 - 3
    • Rewrite as addition: -3 + (-3)
    • Start at 0.
    • Plot -3 by moving 3 units to the left.
    • Add -3 by moving 3 units to the left.

    -3 - 3 = -6

    • The distance from 0 to -6 is 6 units.
    • So the distance = 6
  4. Subtracting Integers on a Number Line

    • Subtract: 5 - (-2)
    • Rewrite as addition: 5 + 2
    • Start at 0.
    • Plot 5 by moving 5 units to the right.
    • Add 2 by moving 2 units to the right.

    5 - (-2) = 7

    • The distance from 0 to 7 is 7 units.

So, here are all the answers:

  • 4 - 7 = -3
  • -2 - 3 = -5
  • -3 - 3 = -6
  • The distance = 6
  • 5 - (-2) = 7
