Let's solve each subtraction problem shown on the number lines step by step. Each number line uses
blue and
green arcs to represent numbers, and we are to compute:
>
Blue number – Green number = ?
We'll analyze each one carefully.
---
Problem 1:
- Blue arc starts at 0 and ends at
6 → Blue = 6
- Green arc starts at 3 and ends at
6 → Green = 3
- So:
6 - 3 = 3
✔ Answer:
6 - 3 = 3
---
Problem 2:
- Blue arc starts at 0 and ends at
5 → Blue = 5
- Green arc starts at 0 and ends at
4 → Green = 4
- So:
5 - 4 = 1
✔ Answer:
5 - 4 = 1
---
Problem 3:
- Blue arc starts at 0 and ends at
3 → Blue = 3
- Green arc starts at 2 and ends at
4 → Green = 2 (since it spans from 2 to 4, that’s a length of 2)
- So:
3 - 2 = 1
✔ Answer:
3 - 2 = 1
---
Problem 4:
- Blue arc starts at 0 and ends at
9 → Blue = 9
- Green arc starts at 8 and ends at
9 → Green = 1 (length from 8 to 9)
- So:
9 - 1 = 8
✔ Answer:
9 - 1 = 8
---
Problem 5:
- Blue arc starts at 0 and ends at
7 → Blue = 7
- Green arc starts at 6 and ends at
7 → Green = 1 (from 6 to 7)
- So:
7 - 1 = 6
✔ Answer:
7 - 1 = 6
---
✔ Final Answers:
1. 6 - 3 =
3
2. 5 - 4 =
1
3. 3 - 2 =
1
4. 9 - 1 =
8
5. 7 - 1 =
6

These problems use number lines to visually represent subtraction as "taking away" or finding the difference between two lengths. The blue arc represents the total (minuend), and the green arc represents the amount being subtracted (subtrahend). The result is the remaining distance.
