Let’s solve each subtraction problem by thinking about “jumping backwards” on a number line.
---
Problem 1: 11 - 5 = ?
Start at 11. Jump back 5 spaces:
- 11 → 10 (1 jump)
- 10 → 9 (2 jumps)
- 9 → 8 (3 jumps)
- 8 → 7 (4 jumps)
- 7 → 6 (5 jumps)
We land on
6.
✔ So, 11 - 5 =
6

Problem 2: 16 - 9 = ?
Start at 16. Jump back 9 spaces:
- 16 → 15 (1)
- 15 → 14 (2)
- 14 → 13 (3)
- 13 → 12 (4)
- 12 → 11 (5)
- 11 → 10 (6)
- 10 → 9 (7)
- 9 → 8 (8)
- 8 → 7 (9)
We land on
7.
✔ So, 16 - 9 =
7

Problem 3: 14 - 6 = ?
Start at 14. Jump back 6 spaces:
- 14 → 13 (1)
- 13 → 12 (2)
- 12 → 11 (3)
- 11 → 10 (4)
- 10 → 9 (5)
- 9 → 8 (6)
We land on
8.
✔ So, 14 - 6 =
8

Final Answer:
1. 6
2. 7
3. 8
