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