To solve the subtraction problems using the number line, we will follow these steps for each problem:
1.
Identify the starting point: This is the first number in the subtraction problem.
2.
Move left on the number line: The number of steps to move left corresponds to the second number in the subtraction problem.
3.
Determine the final position: The number where you land after moving left is the result of the subtraction.
Let's solve each problem step by step:
---
Problem 1: \( 6 - 4 \)
1.
Starting point: 6
2.
Move left: Move 4 steps to the left from 6.
- From 6, move to 5 (1 step).
- From 5, move to 4 (2 steps).
- From 4, move to 3 (3 steps).
- From 3, move to 2 (4 steps).
3.
Final position: 2
So, \( 6 - 4 = 2 \).
---
Problem 2: \( 10 - 5 \)
1.
Starting point: 10
2.
Move left: Move 5 steps to the left from 10.
- From 10, move to 9 (1 step).
- From 9, move to 8 (2 steps).
- From 8, move to 7 (3 steps).
- From 7, move to 6 (4 steps).
- From 6, move to 5 (5 steps).
3.
Final position: 5
So, \( 10 - 5 = 5 \).
---
Problem 3: \( 4 - 3 \)
1.
Starting point: 4
2.
Move left: Move 3 steps to the left from 4.
- From 4, move to 3 (1 step).
- From 3, move to 2 (2 steps).
- From 2, move to 1 (3 steps).
3.
Final position: 1
So, \( 4 - 3 = 1 \).
---
Problem 4: \( 7 - 1 \)
1.
Starting point: 7
2.
Move left: Move 1 step to the left from 7.
- From 7, move to 6 (1 step).
3.
Final position: 6
So, \( 7 - 1 = 6 \).
---
Problem 5: \( 5 - 4 \)
1.
Starting point: 5
2.
Move left: Move 4 steps to the left from 5.
- From 5, move to 4 (1 step).
- From 4, move to 3 (2 steps).
- From 3, move to 2 (3 steps).
- From 2, move to 1 (4 steps).
3.
Final position: 1
So, \( 5 - 4 = 1 \).
---
Final Answers
1. \( 6 - 4 = 2 \)
2. \( 10 - 5 = 5 \)
3. \( 4 - 3 = 1 \)
4. \( 7 - 1 = 6 \)
5. \( 5 - 4 = 1 \)
\[
\boxed{2, 5, 1, 6, 1}
\]
