Math worksheet with subtraction, number line placement, and missing number exercises.

Problem Breakdown and Solution

The image contains several tasks that need to be solved step by step. Let's address each section systematically.

---

#### Task 1: Find the difference
We are asked to subtract the second number from the first number in each pair.

1. 11. \( 3218 - 2871 \)
\[
3218 - 2871 = 347
\]

2. 12. \( 9811 - 4871 \)
\[
9811 - 4871 = 4940
\]

3. 13. \( 8866 - 4498 \)
\[
8866 - 4498 = 4368
\]

4. 14. \( 3441 - 1907 \)
\[
3441 - 1907 = 1534
\]

5. 15. \( 9389 - 8854 \)
\[
9389 - 8854 = 535
\]

6. 16. \( 5174 - 1252 \)
\[
5174 - 1252 = 3922
\]

7. 17. \( 8360 - 6664 \)
\[
8360 - 6664 = 1696
\]

8. 18. \( 2764 - 2422 \)
\[
2764 - 2422 = 342
\]

9. 19. \( 8429 - 2342 \)
\[
8429 - 2342 = 6087
\]

10. 20. \( 9722 - 1451 \)
\[
9722 - 1451 = 8271
\]

#### Task 2: Identify where each set of points should be placed on the number lines

We need to place the given numbers on the provided number lines.

1. 21. Numbers: \( 6327, 6292, 6337, 6287, 6277, 6317 \)
- Number line range: \( 6247 \) to \( 6347 \)
- Placement:
- \( 6277 \): Near the start of the number line.
- \( 6287 \): Slightly to the right of \( 6277 \).
- \( 6292 \): Further to the right of \( 6287 \).
- \( 6317 \): Closer to the middle.
- \( 6327 \): Slightly to the right of \( 6317 \).
- \( 6337 \): Near the end of the number line.

2. 22. Numbers: \( 1059, 1049, 1079, 1024, 1034, 1069 \)
- Number line range: \( 1004 \) to \( 1104 \)
- Placement:
- \( 1024 \): Near the start of the number line.
- \( 1034 \): Slightly to the right of \( 1024 \).
- \( 1049 \): Further to the right of \( 1034 \).
- \( 1059 \): Closer to the middle.
- \( 1069 \): Slightly to the right of \( 1059 \).
- \( 1079 \): Near the end of the number line.

3. 23. Numbers: \( 3560, 3610, 3545, 3540, 3565, 3615 \)
- Number line range: \( 3520 \) to \( 3620 \)
- Placement:
- \( 3540 \): Near the start of the number line.
- \( 3545 \): Slightly to the right of \( 3540 \).
- \( 3560 \): Closer to the middle.
- \( 3565 \): Slightly to the right of \( 3560 \).
- \( 3610 \): Further to the right.
- \( 3615 \): Near the end of the number line.

4. 24. Numbers: \( 214, 219, 244, 174, 169 \)
- Number line range: \( 149 \) to \( 249 \)
- Placement:
- \( 169 \): Near the start of the number line.
- \( 174 \): Slightly to the right of \( 169 \).
- \( 214 \): Closer to the middle.
- \( 219 \): Slightly to the right of \( 214 \).
- \( 244 \): Near the end of the number line.

#### Task 3: Fill in the missing numbers that come before or after the number given

We need to determine the missing numbers based on the context (before or after).

1. 25. Before \( 56 \)
- Missing number: \( 55 \)

2. 26. After \( 3191 \)
- Missing number: \( 3192 \)

3. 27. Before \( 9 \)
- Missing number: \( 8 \)

4. 28. After \( 7 \)
- Missing number: \( 8 \)

5. 29. Before \( 39 \)
- Missing number: \( 38 \)

6. 30. After \( 348 \)
- Missing number: \( 349 \)

7. 31. Before \( 1 \)
- Missing number: \( 0 \)

8. 32. After \( 33 \)
- Missing number: \( 34 \)
