Step-by-step solution for: GRADE 4 TERM 4 MATHEMATICS WORKSHEET • Teacha!
Let’s go through each part of the worksheet step by step.

Part 1: Find the difference (Subtraction problems)
We’ll subtract the bottom number from the top number for each problem.
11.
3218
–2871
─────
Start from right:
8 – 1 = 7
1 – 7 → can’t do, borrow → 11 – 7 = 4 (tens place becomes 0)
0 – 8 → can’t do, borrow from thousands → 10 – 8 = 2 (hundreds place)
2 – 2 = 0 (thousands)
→ 347
Wait — let me recalculate carefully:
3218
-2871
------
Units: 8 - 1 = 7
Tens: 1 - 7 → borrow from hundreds → 11 - 7 = 4; hundreds becomes 1 (was 2)
Hundreds: 1 - 8 → borrow from thousands → 11 - 8 = 3; thousands becomes 2
Thousands: 2 - 2 = 0
So: 347
✔ Correct.
12.
9811
–4871
─────
1 - 1 = 0
1 - 7 → borrow → 11 - 7 = 4; tens becomes 0
0 - 8 → borrow → 10 - 8 = 2; hundreds becomes 7
7 - 4 = 3
9 - 4 = 5? Wait — thousands: 9 became 8 after borrowing? Let's redo:
Actually:
9811
-4871
------
Units: 1 - 1 = 0
Tens: 1 - 7 → borrow from hundreds → 11 - 7 = 4; hundreds digit 8 becomes 7
Hundreds: 7 - 8 → borrow from thousands → 17 - 8 = 9; thousands digit 9 becomes 8
Thousands: 8 - 4 = 4
→ 4940
Check: 4871 + 4940 = 9811?
4871 + 4940 = 9811 → yes.
✔ Correct.
13.
8866
–4498
─────
6 - 8 → borrow → 16 - 8 = 8; tens becomes 5
5 - 9 → borrow → 15 - 9 = 6; hundreds becomes 7
7 - 4 = 3
8 - 4 = 4
→ 4368
Check: 4498 + 4368 = 8866?
4498 + 4368 = 8866 → yes.
✔ Correct.
14.
3441
–1907
─────
1 - 7 → borrow → 11 - 7 = 4; tens becomes 3
3 - 0 = 3
4 - 9 → borrow → 14 - 9 = 5; thousands becomes 2
2 - 1 = 1
→ 1534
Check: 1907 + 1534 = 3441 → yes.
✔ Correct.
15.
9389
–8854
─────
9 - 4 = 5
8 - 5 = 3
3 - 8 → borrow → 13 - 8 = 5; thousands becomes 8
8 - 8 = 0
→ 535
Check: 8854 + 535 = 9389 → yes.
✔ Correct.
16.
5174
–1252
─────
4 - 2 = 2
7 - 5 = 2
1 - 2 → borrow → 11 - 2 = 9; thousands becomes 4
4 - 1 = 3
→ 3922
Check: 1252 + 3922 = 5174 → yes.
✔ Correct.
17.
8360
–6664
─────
0 - 4 → borrow → 10 - 4 = 6; tens becomes 5
5 - 6 → borrow → 15 - 6 = 9; hundreds becomes 2
2 - 6 → borrow → 12 - 6 = 6; thousands becomes 7
7 - 6 = 1
→ 1696
Check: 6664 + 1696 = 8360 → yes.
✔ Correct.
18.
2764
–2422
─────
4 - 2 = 2
6 - 2 = 4
7 - 4 = 3
2 - 2 = 0
→ 342
Check: 2422 + 342 = 2764 → yes.
✔ Correct.
19.
8429
–2342
─────
9 - 2 = 7
2 - 4 → borrow → 12 - 4 = 8; hundreds becomes 3
3 - 3 = 0
8 - 2 = 6
→ 6087
Check: 2342 + 6087 = 8429 → yes.
✔ Correct.
20.
9722
–1451
─────
2 - 1 = 1
2 - 5 → borrow → 12 - 5 = 7; hundreds becomes 6
6 - 4 = 2
9 - 1 = 8
→ 8271
Check: 1451 + 8271 = 9722 → yes.
✔ Correct.

Part 2: Place points on number lines
We need to sort the given numbers and place them in order between the marked endpoints.
21. Numbers: 6327, 6292, 6337, 6287, 6277, 6317
Number line: from 6247 to 6347, with marks at 6297 and others.
First, sort the numbers:
6277, 6287, 6292, 6317, 6327, 6337
Now look at the number line:
Left end: 6247
Then there are tick marks — we need to figure out the interval.
From 6247 to 6297 is 50 units. There are 5 intervals? Let’s count ticks.
Looking at the diagram description:
It shows:
6247 ——|——|——|——|——6297——|——|——|——|——6347
Assuming equal spacing, from 6247 to 6297 is 50, divided into 5 segments → each segment = 10.
Similarly, 6297 to 6347 is also 50 → 5 segments of 10.
So ticks are at:
6247, 6257, 6267, 6277, 6287, 6297, 6307, 6317, 6327, 6337, 6347
Perfect! So our numbers fit exactly on these ticks.
Sorted:
6277 → 4th tick from left
6287 → 5th
6292 → not a multiple of 10? Wait — 6292 is between 6287 and 6297? But the ticks are every 10.
Wait — maybe I miscounted.
If from 6247 to 6297 is 50, and there are 5 intervals, then each interval is 10.
But 6292 is not aligned with any tick if ticks are at +10.
Perhaps the ticks are labeled only at key points, and we place the numbers proportionally.
But looking back at the problem: “Identify where each set of points should be placed”
And under the number line, there are blanks: ___ ___ ___ ___ ___ ___
Probably 6 blanks for 6 numbers.
The number line has major ticks at 6247, 6297, 6347.
Between 6247 and 6297: 50 units. If we assume 5 small ticks, each 10 apart.
Similarly between 6297 and 6347: 50 units, 5 ticks.
So positions:
Left side (before 6297):
6247, 6257, 6267, 6277, 6287, 6297
Right side (after 6297):
6307, 6317, 6327, 6337, 6347
Our numbers:
6277 → matches 6277
6287 → matches 6287
6292 → between 6287 and 6297 → closer to 6297? 6292 - 6287 = 5, so halfway? But since no tick, perhaps it goes in the blank before 6297? The diagram might have spaces for placement.
Actually, looking at the original image description, under the number line, there are six underscores: three on the left of 6297, three on the right? Or distributed.
To simplify, since this is likely expecting us to list the numbers in order along the line, and the blanks correspond to their positions.
Sorted order:
6277, 6287, 6292, 6317, 6327, 6337
On the number line from left to right:
After 6247, first blank: 6277? No, too far.
Better to think: the number line starts at 6247, ends at 6347.
Each unit increase moves right.
So smallest number 6277 should be near left, largest 6337 near right.
Since the line has marks at 6247, 6297, 6347, and presumably intermediate ticks every 10 or 5.
But to avoid overcomplicating, and since this is a common type, I'll assume the blanks are meant to be filled with the numbers in ascending order as they appear on the line.
For 21: sorted numbers: 6277, 6287, 6292, 6317, 6327, 6337
Place them left to right on the line.
Similarly for others.
But since the instruction is "identify where", and there are blanks under the line, probably we just list the numbers in order corresponding to their position.
However, without seeing the exact blank positions, I'll provide the sorted order which indicates their placement.
But for accuracy, let's do all.
22. Numbers: 1059, 1049, 1079, 1024, 1034, 1069
Sort: 1024, 1034, 1049, 1059, 1069, 1079
Number line: 1004 to 1104, with mark at 1054.
Range 100 units. Likely ticks every 10 or 20.
From 1004 to 1054 is 50, to 1104 is another 50.
Assume ticks every 10: 1004, 1014, 1024, 1034, 1044, 1054, 1064, 1074, 1084, 1094, 1104
Our numbers:
1024 → matches
1034 → matches
1049 → between 1044 and 1054
1059 → between 1054 and 1064
1069 → between 1064 and 1074
1079 → between 1074 and 1084
But again, for placement, sorted order is fine.
23. Numbers: 3560, 3610, 3545, 3540, 3565, 3615
Sort: 3540, 3545, 3560, 3565, 3610, 3615
Number line: 3520 to 3620, mark at 3570.
Range 100 units. Ticks likely every 10.
3520, 3530, 3540, 3550, 3560, 3570, 3580, 3590, 3600, 3610, 3620
Matches:
3540, 3545 (between 3540 and 3550), 3560, 3565 (between 3560 and 3570), 3610, 3615 (between 3610 and 3620)
24. Numbers: 214, 219, 244, 174, 169, 179
Sort: 169, 174, 179, 214, 219, 244
Number line: 149 to 249, mark at 199.
Range 100 units. Ticks every 10: 149,159,169,179,189,199,209,219,229,239,249
Matches:
169, 174 (between 179? 174 is between 169 and 179), 179, 214 (between 209 and 219), 219, 244 (between 239 and 249)
Again, sorted order gives placement.

Part 3: Fill in missing numbers before or after
These are simple predecessor/successor.
25. _ 56 → before 56 is 55
26. _ _ 3191 → two before: 3189, 3190? But it says "comes before or after", and there are two blanks. Probably one before and one after? But format is "_ _ 3191" — likely two numbers before? Or one before and one after? Looking at others:
27. _ 9 → before 9 is 8
28. _ 7 → before 7 is 6
29. _ 39 → before 39 is 38
30. _ _ 348 → two blanks, probably two before: 346, 347? Or one before and one after? But 31 is "1 _" which is after 1, so 2.
Pattern:
25: one blank before → 55
26: two blanks before 3191 → 3189, 3190? But typically, "fill in missing numbers that come before or after" — for 26, it might be one before and one after, but written as "_ _ 3191", which suggests both before.
Look at 31: "1 _" → after 1, so 2
32: "33 _" → after 33, so 34
For 26: "_ _ 3191" — likely two numbers before: 3189 and 3190? But that would be decreasing. Usually, we write in order.
Perhaps it's "the number before and the number after", but formatted poorly.
Check the original: "26. ______ 3 191" — two blanks before 3191.
In context, probably means fill in the two numbers immediately before 3191.
Similarly, 30: "______ 348" — two blanks before 348.
But 25: "_ 56" — one before.
27: "_ 9" — one before.
28: "_ 7" — one before.
29: "_ 39" — one before.
31: "1 _" — one after.
32: "33 _" — one after.
So for 26 and 30, two blanks before.
Thus:
26. Before 3191: 3190, 3189? But usually we write in increasing order, so perhaps 3189 and 3190, but the blanks are before, so likely 3190 then 3189? That doesn't make sense.
Perhaps it's "the previous two numbers", so 3189 and 3190, listed as 3189, 3190.
But in the blank, it might be expected as 3190 and 3189? Unlikely.
Another interpretation: perhaps for 26, it's "___ 3191" meaning the number before is ___, and there's an extra blank? But it says "two blanks".
Looking back at user input: "26. ______ 3 191" — probably two separate blanks, but in text it's shown as one underline.
In the original image, it might be clear.
To resolve, let's see standard practice.
Typically, such exercises ask for immediate predecessor or successor.
For 26, since there are two blanks before 3191, it might be a mistake, or perhaps it's "fill in the number before and the number after", but written as "_ _ 3191" which is ambiguous.
Notice that in 31 and 32, it's "1 _" and "33 _", clearly after.
For 25-29, it's "_ X" , so before.
For 26 and 30, it's "__ X", so two before.
I think it's safe to assume:
26. Two numbers before 3191: 3190 and 3189, but listed in order: 3189, 3190? Or 3190, 3189? Since it's "before", and blanks are to the left, probably 3190 then 3189, but that's descending.
Better to list in numerical order: 3189 and 3190.
But the blanks are positioned before 3191, so likely the first blank is 3190, second is 3189? That seems odd.
Perhaps it's a typo, and it's meant to be one before and one after, but formatted as two blanks.
Given that, and to match the pattern, I'll assume for 26: the number before is 3190, and perhaps the other blank is for something else, but I think it's two predecessors.
Let's calculate:
Immediate predecessor of 3191 is 3190.
Predecessor of that is 3189.
So if two blanks before, it could be 3189 and 3190, but in what order? In the sequence, when placing on a line, 3189 comes before 3190.
So probably: 3189, 3190
Similarly for 30: before 348: 347, 346? Or 346, 347.
I think it's 346 and 347 for 30.
Confirm with 26: 3189 and 3190.
Yes.
So:
25. 55
26. 3189, 3190 (but since two blanks, perhaps write as 3189 and 3190)
27. 8
28. 6
29. 38
30. 346, 347
31. 2
32. 34
For 26 and 30, since there are two blanks, we provide two numbers.
Now, compiling all answers.

Part 2: Number Lines
Since the task is to identify where to place, and without visual blanks, we provide the sorted order for each, which indicates their relative positions.
21. Sorted: 6277, 6287, 6292, 6317, 6327, 6337
22. Sorted: 1024, 1034, 1049, 1059, 1069, 1079
23. Sorted: 3540, 3545, 3560, 3565, 3610, 3615
24. Sorted: 169, 174, 179, 214, 219, 244
Part 3: Missing Numbers
25. 55
26. 3189, 3190 (assuming two before)
27. 8
28. 6
29. 38
30. 346, 347
31. 2
32. 34
For 26 and 30, if the blanks are meant to be filled sequentially, we write the numbers in order.
Now, for the final answer, since the user didn't specify which part, but the entire worksheet, I'll provide all.
But typically, in such responses, we list all answers clearly.
Since the instruction is to provide final answer after reasoning, and this is a multi-part question, I'll box the entire set.
But to follow format, perhaps list them.
Given that, I'll write the final answers as per sections.
But for simplicity, since the assistant is to provide the solution, I'll compile.
Note: For number lines, since it's placement, and no specific output format, providing sorted lists is sufficient.
Similarly for missing numbers.
So Final Answer will include all.
But to adhere to "provide only the final correct answer", and since it's multiple, I'll list them.
Perhaps the user expects the subtraction answers primarily, but the image has all parts.
To be safe, I'll provide all.
In the response, after reasoning, I'll state the answers.
But the format says "Final Answer: [only the final correct answer]"
So for multi-part, I need to present it neatly.
I think for this context, I'll list the subtraction results first, as they are numerical answers, and for others, describe briefly.
But to be precise, let's see.
Another way: since the task is to solve the problem, and the problem includes all, I'll provide a comprehensive final answer.
But to keep it clean, I'll box the subtraction answers as they are straightforward calculations, and for others, mention.
However, the instruction is to solve the problem accurately, so all parts.
I think for the final answer section, I'll write:
For subtraction problems (11-20):
11. 347, 12. 4940, 13. 4368, 14. 1534, 15. 535, 16. 3922, 17. 1696, 18. 342, 19. 6087, 20. 8271
For number line placements (21-24), the numbers should be placed in ascending order on the respective number lines.
For missing numbers (25-32):
25. 55, 26. 3189 and 3190, 27. 8, 28. 6, 29. 38, 30. 346 and 347, 31. 2, 32. 34
But for 26 and 30, since there are two blanks, specifying two numbers.
Now, to confirm 26: if it's "_ _ 3191", and we put 3189 and 3190, but in what order? Typically, when filling blanks before a number, we fill from left to right with increasing values, so first blank is 3189, second is 3190? But 3189 is smaller, so it should be further left.
In the sequence, on a number line, 3189 is left of 3190, which is left of 3191.
So if there are two blanks before 3191, the leftmost blank is 3189, next is 3190.
Similarly for 30: 346, then 347.
Yes.
So for 26: 3189, 3190
30: 346, 347
Now, writing final answer.

Part 2: Place points on number lines
We need to sort the given numbers and place them in order between the marked endpoints.
21. Numbers: 6327, 6292, 6337, 6287, 6277, 6317
Number line: from 6247 to 6347, with marks at 6297 and others.
First, sort the numbers:
6277, 6287, 6292, 6317, 6327, 6337
Now look at the number line:
Left end: 6247
Then there are tick marks — we need to figure out the interval.
From 6247 to 6297 is 50 units. There are 5 intervals? Let’s count ticks.
Looking at the diagram description:
It shows:
6247 ——|——|——|——|——6297——|——|——|——|——6347
Assuming equal spacing, from 6247 to 6297 is 50, divided into 5 segments → each segment = 10.
Similarly, 6297 to 6347 is also 50 → 5 segments of 10.
So ticks are at:
6247, 6257, 6267, 6277, 6287, 6297, 6307, 6317, 6327, 6337, 6347
Perfect! So our numbers fit exactly on these ticks.
Sorted:
6277 → 4th tick from left
6287 → 5th
6292 → not a multiple of 10? Wait — 6292 is between 6287 and 6297? But the ticks are every 10.
Wait — maybe I miscounted.
If from 6247 to 6297 is 50, and there are 5 intervals, then each interval is 10.
But 6292 is not aligned with any tick if ticks are at +10.
Perhaps the ticks are labeled only at key points, and we place the numbers proportionally.
But looking back at the problem: “Identify where each set of points should be placed”
And under the number line, there are blanks: ___ ___ ___ ___ ___ ___
Probably 6 blanks for 6 numbers.
The number line has major ticks at 6247, 6297, 6347.
Between 6247 and 6297: 50 units. If we assume 5 small ticks, each 10 apart.
Similarly between 6297 and 6347: 50 units, 5 ticks.
So positions:
Left side (before 6297):
6247, 6257, 6267, 6277, 6287, 6297
Right side (after 6297):
6307, 6317, 6327, 6337, 6347
Our numbers:
6277 → matches 6277
6287 → matches 6287
6292 → between 6287 and 6297 → closer to 6297? 6292 - 6287 = 5, so halfway? But since no tick, perhaps it goes in the blank before 6297? The diagram might have spaces for placement.
Actually, looking at the original image description, under the number line, there are six underscores: three on the left of 6297, three on the right? Or distributed.
To simplify, since this is likely expecting us to list the numbers in order along the line, and the blanks correspond to their positions.
Sorted order:
6277, 6287, 6292, 6317, 6327, 6337
On the number line from left to right:
After 6247, first blank: 6277? No, too far.
Better to think: the number line starts at 6247, ends at 6347.
Each unit increase moves right.
So smallest number 6277 should be near left, largest 6337 near right.
Since the line has marks at 6247, 6297, 6347, and presumably intermediate ticks every 10 or 5.
But to avoid overcomplicating, and since this is a common type, I'll assume the blanks are meant to be filled with the numbers in ascending order as they appear on the line.
For 21: sorted numbers: 6277, 6287, 6292, 6317, 6327, 6337
Place them left to right on the line.
Similarly for others.
But since the instruction is "identify where", and there are blanks under the line, probably we just list the numbers in order corresponding to their position.
However, without seeing the exact blank positions, I'll provide the sorted order which indicates their placement.
But for accuracy, let's do all.
22. Numbers: 1059, 1049, 1079, 1024, 1034, 1069
Sort: 1024, 1034, 1049, 1059, 1069, 1079
Number line: 1004 to 1104, with mark at 1054.
Range 100 units. Likely ticks every 10 or 20.
From 1004 to 1054 is 50, to 1104 is another 50.
Assume ticks every 10: 1004, 1014, 1024, 1034, 1044, 1054, 1064, 1074, 1084, 1094, 1104
Our numbers:
1024 → matches
1034 → matches
1049 → between 1044 and 1054
1059 → between 1054 and 1064
1069 → between 1064 and 1074
1079 → between 1074 and 1084
But again, for placement, sorted order is fine.
23. Numbers: 3560, 3610, 3545, 3540, 3565, 3615
Sort: 3540, 3545, 3560, 3565, 3610, 3615
Number line: 3520 to 3620, mark at 3570.
Range 100 units. Ticks likely every 10.
3520, 3530, 3540, 3550, 3560, 3570, 3580, 3590, 3600, 3610, 3620
Matches:
3540, 3545 (between 3540 and 3550), 3560, 3565 (between 3560 and 3570), 3610, 3615 (between 3610 and 3620)
24. Numbers: 214, 219, 244, 174, 169, 179
Sort: 169, 174, 179, 214, 219, 244
Number line: 149 to 249, mark at 199.
Range 100 units. Ticks every 10: 149,159,169,179,189,199,209,219,229,239,249
Matches:
169, 174 (between 179? 174 is between 169 and 179), 179, 214 (between 209 and 219), 219, 244 (between 239 and 249)
Again, sorted order gives placement.

Part 3: Fill in missing numbers before or after
These are simple predecessor/successor.
25. _ 56 → before 56 is 55
26. _ _ 3191 → two before: 3189, 3190? But it says "comes before or after", and there are two blanks. Probably one before and one after? But format is "_ _ 3191" — likely two numbers before? Or one before and one after? Looking at others:
27. _ 9 → before 9 is 8
28. _ 7 → before 7 is 6
29. _ 39 → before 39 is 38
30. _ _ 348 → two blanks, probably two before: 346, 347? Or one before and one after? But 31 is "1 _" which is after 1, so 2.
Pattern:
25: one blank before → 55
26: two blanks before 3191 → 3189, 3190? But typically, "fill in missing numbers that come before or after" — for 26, it might be one before and one after, but written as "_ _ 3191", which suggests both before.
Look at 31: "1 _" → after 1, so 2
32: "33 _" → after 33, so 34
For 26: "_ _ 3191" — likely two numbers before: 3189 and 3190? But that would be decreasing. Usually, we write in order.
Perhaps it's "the number before and the number after", but formatted poorly.
Check the original: "26. ______ 3 191" — two blanks before 3191.
In context, probably means fill in the two numbers immediately before 3191.
Similarly, 30: "______ 348" — two blanks before 348.
But 25: "_ 56" — one before.
27: "_ 9" — one before.
28: "_ 7" — one before.
29: "_ 39" — one before.
31: "1 _" — one after.
32: "33 _" — one after.
So for 26 and 30, two blanks before.
Thus:
26. Before 3191: 3190, 3189? But usually we write in increasing order, so perhaps 3189 and 3190, but the blanks are before, so likely 3190 then 3189? That doesn't make sense.
Perhaps it's "the previous two numbers", so 3189 and 3190, listed as 3189, 3190.
But in the blank, it might be expected as 3190 and 3189? Unlikely.
Another interpretation: perhaps for 26, it's "___ 3191" meaning the number before is ___, and there's an extra blank? But it says "two blanks".
Looking back at user input: "26. ______ 3 191" — probably two separate blanks, but in text it's shown as one underline.
In the original image, it might be clear.
To resolve, let's see standard practice.
Typically, such exercises ask for immediate predecessor or successor.
For 26, since there are two blanks before 3191, it might be a mistake, or perhaps it's "fill in the number before and the number after", but written as "_ _ 3191" which is ambiguous.
Notice that in 31 and 32, it's "1 _" and "33 _", clearly after.
For 25-29, it's "_ X" , so before.
For 26 and 30, it's "__ X", so two before.
I think it's safe to assume:
26. Two numbers before 3191: 3190 and 3189, but listed in order: 3189, 3190? Or 3190, 3189? Since it's "before", and blanks are to the left, probably 3190 then 3189, but that's descending.
Better to list in numerical order: 3189 and 3190.
But the blanks are positioned before 3191, so likely the first blank is 3190, second is 3189? That seems odd.
Perhaps it's a typo, and it's meant to be one before and one after, but formatted as two blanks.
Given that, and to match the pattern, I'll assume for 26: the number before is 3190, and perhaps the other blank is for something else, but I think it's two predecessors.
Let's calculate:
Immediate predecessor of 3191 is 3190.
Predecessor of that is 3189.
So if two blanks before, it could be 3189 and 3190, but in what order? In the sequence, when placing on a line, 3189 comes before 3190.
So probably: 3189, 3190
Similarly for 30: before 348: 347, 346? Or 346, 347.
I think it's 346 and 347 for 30.
Confirm with 26: 3189 and 3190.
Yes.
So:
25. 55
26. 3189, 3190 (but since two blanks, perhaps write as 3189 and 3190)
27. 8
28. 6
29. 38
30. 346, 347
31. 2
32. 34
For 26 and 30, since there are two blanks, we provide two numbers.
Now, compiling all answers.

For 26 and 30, if the blanks are meant to be filled sequentially, we write the numbers in order.
Now, for the final answer, since the user didn't specify which part, but the entire worksheet, I'll provide all.
But typically, in such responses, we list all answers clearly.
Since the instruction is to provide final answer after reasoning, and this is a multi-part question, I'll box the entire set.
But to follow format, perhaps list them.
Given that, I'll write the final answers as per sections.
But for simplicity, since the assistant is to provide the solution, I'll compile.
Note: For number lines, since it's placement, and no specific output format, providing sorted lists is sufficient.
Similarly for missing numbers.
So Final Answer will include all.
But to adhere to "provide only the final correct answer", and since it's multiple, I'll list them.
Perhaps the user expects the subtraction answers primarily, but the image has all parts.
To be safe, I'll provide all.
In the response, after reasoning, I'll state the answers.
But the format says "Final Answer: [only the final correct answer]"
So for multi-part, I need to present it neatly.
I think for this context, I'll list the subtraction results first, as they are numerical answers, and for others, describe briefly.
But to be precise, let's see.
Another way: since the task is to solve the problem, and the problem includes all, I'll provide a comprehensive final answer.
But to keep it clean, I'll box the subtraction answers as they are straightforward calculations, and for others, mention.
However, the instruction is to solve the problem accurately, so all parts.
I think for the final answer section, I'll write:
For subtraction problems (11-20):
11. 347, 12. 4940, 13. 4368, 14. 1534, 15. 535, 16. 3922, 17. 1696, 18. 342, 19. 6087, 20. 8271
For number line placements (21-24), the numbers should be placed in ascending order on the respective number lines.
For missing numbers (25-32):
25. 55, 26. 3189 and 3190, 27. 8, 28. 6, 29. 38, 30. 346 and 347, 31. 2, 32. 34
But for 26 and 30, since there are two blanks, specifying two numbers.
Now, to confirm 26: if it's "_ _ 3191", and we put 3189 and 3190, but in what order? Typically, when filling blanks before a number, we fill from left to right with increasing values, so first blank is 3189, second is 3190? But 3189 is smaller, so it should be further left.
In the sequence, on a number line, 3189 is left of 3190, which is left of 3191.
So if there are two blanks before 3191, the leftmost blank is 3189, next is 3190.
Similarly for 30: 346, then 347.
Yes.
So for 26: 3189, 3190
30: 346, 347
Now, writing final answer.
