Let’s solve each problem step by step. We’ll go row by row, left to right, and calculate each expression carefully.

---

First Row (Top Section):

1. 6 ÷ – = 2 → This means: “6 divided by what number equals 2?”
→ 6 ÷ 3 = 2 → So blank is 3

2. 24 ÷ – = 8 → 24 ÷ ? = 8 → 24 ÷ 3 = 8 → Blank is 3

3. 15 ÷ – = 5 → 15 ÷ ? = 5 → 15 ÷ 3 = 5 → Blank is 3

4. 9 ÷ – = 3 → 9 ÷ ? = 3 → 9 ÷ 3 = 3 → Blank is 3

5. 18 ÷ – = 6 → 18 ÷ ? = 6 → 18 ÷ 3 = 6 → Blank is 3

6. 12 ÷ – = 4 → 12 ÷ ? = 4 → 12 ÷ 3 = 4 → Blank is 3

Wait — let me double-check that last one: 12 ÷ 3 = 4 → Yes, correct.

But hold on — looking again at the image layout, maybe I misread the order? Let me recheck based on actual positions in the image.

Actually, looking more carefully at the structure:

The top section has two rows of problems with blanks for divisors, then below them are addition problems.

Let me organize it properly as per the image layout.

---

Looking again — the first block (top-left) has:

Row 1:
- 6 ÷ _ = 2 → answer: 3
- 24 ÷ _ = 8 → answer: 3
- 15 ÷ _ = 5 → answer: 3
- 9 ÷ _ = 3 → answer: 3
- 18 ÷ _ = 6 → answer: 3
- 12 ÷ _ = 4 → answer: 3

Then Row 2 (addition):
- 6 + 3 = 2 → Wait, that can’t be right. 6+3=9, not 2. That must be a typo or misalignment?

Wait — no! Looking again — perhaps the second row is NOT part of the same equation? Maybe it's separate?

Actually, looking at the full image description from user — it seems like there are multiple blocks.

Let me break down the entire worksheet into sections as shown.

From the original input, it appears there are 4 main blocks (separated by lines), each containing division and addition/subtraction problems.

Let me tackle them one block at a time.

---

BLOCK 1 (Top Left)

Division problems (first row):

- 6 ÷ _ = 2 → 6 ÷ 3 = 2 → 3
- 24 ÷ _ = 8 → 24 ÷ 3 = 8 → 3
- 15 ÷ _ = 5 → 15 ÷ 3 = 5 → 3
- 9 ÷ _ = 3 → 9 ÷ 3 = 3 → 3
- 18 ÷ _ = 6 → 18 ÷ 3 = 6 → 3
- 12 ÷ _ = 4 → 12 ÷ 3 = 4 → 3

Addition problems (second row):

- 6 + 3 = _ → 9
- 24 + 3 = _ → 27
- 15 + 3 = _ → 18
- 9 + 3 = _ → 12
- 18 + 3 = _ → 21
- 12 + 3 = _ → 15

Wait — but in the original text, it says:

“6 + 3 = 2” — that doesn't make sense. Probably a formatting error.

Looking back at user’s input:

It says:

```
| 6 ÷ - = 2 | 24 ÷ - = 8 | 15 ÷ - = 5 | 9 ÷ - = 3 | 18 ÷ - = 6 | 12 ÷ - = 4 |
| 6 + 3 = 2 | 24 + 3 = 7 | 15 + 3 = 7 | 9 + 3 = 4 | 18 + 3 = 9 | 12 + 3 = 6 |
```

That can’t be right — 6+3≠2, etc. These must be typos or misalignments.

Wait — perhaps the second row is meant to be the *answers* to the division? No, because 6÷3=2, so if they wrote “6 + 3 = 2”, that’s wrong.

Alternatively — maybe the second row is actually showing the divisor used? Like, for 6 ÷ _ = 2, they’re saying the blank is 3, and then writing “6 + 3 = 9” but mistakenly wrote “=2”? That doesn’t fit.

Another possibility: The second row is unrelated — just additional problems to solve.

But 6+3=2 is mathematically false. So likely, those numbers after “=” are not answers — maybe they are labels or something else?

Wait — looking at the very end of the user’s message, there’s another set:

In the bottom half, we have:

```
| 24 ÷ 3 = 8 | 24 + 3 = 5 | 15 + 3 = 3 | 12 ÷ 3 = 3 | 15 ÷ 3 = 5 | 6 ÷ 3 = 2 |
```

Again, 24+3=5? That’s impossible.

I think there’s a major formatting issue here. Perhaps the “= X” parts in the addition rows are not meant to be equations to solve, but rather indicators of which column they belong to? Or maybe it’s a copy-paste error.

Alternative approach: Ignore the “= X” in the addition rows and treat them as standalone addition problems where you compute the sum.

Similarly, for subtraction rows later.

Let me assume that in rows like:

“6 + 3 = 2” — this is probably a mistake, and it should be “6 + 3 = __” and we fill in 9.

Same for others.

Perhaps the numbers after “=” in those rows are actually the *column headers* or something, but that doesn’t make sense.

Wait — looking at the full structure again:

User wrote:

```
| 6 ÷ - = 2 | 24 ÷ - = 8 | ... |
| 6 + 3 = 2 | 24 + 3 = 7 | ... |
```

Notice that in the first column: 6 ÷ _ = 2, and below it 6 + 3 = 2 — both equal 2? That suggests that maybe the “=2” is not the result of the operation, but an identifier? Unlikely.

Another idea: Perhaps the “=2”, “=8”, etc., in the first row are the results, and we need to find the divisor. Then in the second row, “6 + 3 = 2” might mean “what do you add to 6 to get 2?” which would be -4, but that’s too advanced.

This is confusing.

Let me look at the third block, which has:

```
| 24 ÷ 3 = 8 | 24 + 3 = 5 | 15 + 3 = 3 | 12 ÷ 3 = 3 | 15 ÷ 3 = 5 | 6 ÷ 3 = 2 |
```

Here, 24 ÷ 3 = 8 is correct. But 24 + 3 = 5 is wrong — unless it’s 24 - 3 = 21, not 5.

Wait — 24 - 19 = 5? Not helpful.

Perhaps the “=5” is a typo and should be “=27”? But why write 5?

Another thought: Maybe the numbers after “=” in the addition/subtraction rows are the *answers*, and we need to verify or something? But that doesn’t match.

Let’s try a different strategy. Look at the very last part of the user’s input:

There is a section:

```
| 6 ÷ 3 = 2 | 24 ÷ 3 = 8 | 15 ÷ 3 = 5 | 12 ÷ 3 = 3 | 15 ÷ 3 = 5 | 6 ÷ 3 = 2 |
```

These are all correct divisions.

Then above that:

```
| 24 ÷ 3 = 8 | 24 + 3 = 5 | 15 + 3 = 3 | 12 ÷ 3 = 3 | 15 ÷ 3 = 5 | 6 ÷ 3 = 2 |
```

Here, 24 + 3 = 5 is incorrect; it should be 27. Similarly, 15 + 3 = 3 is wrong; should be 18.

Unless... wait a minute. What if the “+” is actually “-”? Let’s check:

24 - 3 = 21, not 5.

15 - 3 = 12, not 3.

Still not matching.

What if it’s division? 24 ÷ 3 = 8, already done.

Another idea: Perhaps the “=5” is not the result, but the problem number or something. But that seems unlikely.

Let’s consider that there might be a systematic error in how the user transcribed the image. For example, in some educational worksheets, they have columns where you solve division, then use the quotient in an addition problem.

For instance, in Block 1:

First row: 6 ÷ _ = 2 → so divisor is 3.

Second row: 6 + 3 = ? → 9, but they wrote “=2”, which might be a mistake.

Perhaps the “=2” in the second row is meant to be the answer to the first row, and the second row is incomplete.

This is getting too messy.

Let me instead focus on the parts that make sense and are clearly solvable.

From the user’s input, there are several clear division problems where we need to find the missing divisor.

For example:

- 6 ÷ _ = 2 → answer: 3
- 24 ÷ _ = 8 → answer: 3
- 15 ÷ _ = 5 → answer: 3
- 9 ÷ _ = 3 → answer: 3
- 18 ÷ _ = 6 → answer: 3
- 12 ÷ _ = 4 → answer: 3

All of these require dividing by 3.

Then there are addition problems like:

- 6 + 3 = ? → 9
- 24 + 3 = ? → 27
- 15 + 3 = ? → 18
- 9 + 3 = ? → 12
- 18 + 3 = ? → 21
- 12 + 3 = ? → 15

And subtraction problems later:

- 27 - 3 = ? → 24
- 18 - 3 = ? → 15
- etc.

Also, in the bottom part, there are direct calculations like:

- 24 ÷ 3 = 8 (given)
- 24 + 3 = ? → should be 27, but written as "=5" — probably a typo.

Given the confusion, I will assume that for any row that says "A + B = C", if C is given and is incorrect, we ignore C and compute A+B. If it's "A - B = C", same thing.

But in the user's input, for example:

"24 + 3 = 5" — this is likely a transcription error, and it should be "24 + 3 = __" and we put 27.

Similarly, "15 + 3 = 3" should be 18.

So I'll proceed under that assumption.

Let me now systematically solve all problems as intended.

---

Section 1: Find the missing divisor (first row of each block)

Block 1:
- 6 ÷ _ = 2 → 3
- 24 ÷ _ = 8 → 3
- 15 ÷ _ = 5 → 3
- 9 ÷ _ = 3 → 3
- 18 ÷ _ = 6 → 3
- 12 ÷ _ = 4 → 3

Block 2:
- 18 ÷ _ = 6 → 3
- 21 ÷ _ = 7 → 3
- 27 ÷ _ = 9 → 3
- 18 ÷ _ = 6 → 3
- 12 ÷ _ = 4 → 3
- 21 ÷ _ = 7 → 3
- 27 ÷ _ = 9 → 3
- 12 ÷ _ = 4 → 3
- 18 ÷ _ = 6 → 3
- 27 ÷ _ = 9 → 3
- 12 ÷ _ = 4 → 3
- 21 ÷ _ = 7 → 3
- 21 ÷ _ = 7 → 3
- 6 ÷ _ = 2 → 3

Wait, this is repeating. Let's list unique ones.

From Block 2 first row:
- 18 ÷ _ = 6 → 3
- 21 ÷ _ = 7 → 3
- 27 ÷ _ = 9 → 3
- 18 ÷ _ = 6 → 3 (duplicate)
- 12 ÷ _ = 4 → 3
- 21 ÷ _ = 7 → 3 (duplicate)
- 27 ÷ _ = 9 → 3 (duplicate)
- 12 ÷ _ = 4 → 3 (duplicate)
- 18 ÷ _ = 6 → 3 (duplicate)
- 27 ÷ _ = 9 → 3 (duplicate)
- 12 ÷ _ = 4 → 3 (duplicate)
- 21 ÷ _ = 7 → 3 (duplicate)
- 21 ÷ _ = 7 → 3 (duplicate)
- 6 ÷ _ = 2 → 3

So all are 3.

Block 3:
- 24 ÷ _ = 8 → 3
- 15 ÷ _ = 5 → 3
- 9 ÷ _ = 3 → 3
- 18 ÷ _ = 6 → 3
- 12 ÷ _ = 4 → 3
- 24 ÷ _ = 8 → 3 (duplicate)
- 15 ÷ _ = 5 → 3 (duplicate)
- 9 ÷ _ = 3 → 3 (duplicate)
- 18 ÷ _ = 6 → 3 (duplicate)
- 12 ÷ _ = 4 → 3 (duplicate)

All 3.

Block 4:
- 27 ÷ _ = 9 → 3
- 18 ÷ _ = 6 → 3
- 27 ÷ _ = 9 → 3 (duplicate)
- 18 ÷ _ = 6 → 3 (duplicate)
- 27 ÷ _ = 9 → 3 (duplicate)
- 18 ÷ _ = 6 → 3 (duplicate)

All 3.

So for all "find the divisor" problems, the answer is 3.

Now for the addition and subtraction problems.

In Block 1, second row:
- 6 + 3 = ? → 9
- 24 + 3 = ? → 27
- 15 + 3 = ? → 18
- 9 + 3 = ? → 12
- 18 + 3 = ? → 21
- 12 + 3 = ? → 15

In Block 2, second row:
- 18 + 3 = ? → 21
- 21 + 3 = ? → 24
- 27 + 3 = ? → 30
- 18 + 3 = ? → 21 (duplicate)
- 12 + 3 = ? → 15
- 21 + 3 = ? → 24 (duplicate)
- 27 + 3 = ? → 30 (duplicate)
- 12 + 3 = ? → 15 (duplicate)
- 18 + 3 = ? → 21 (duplicate)
- 27 + 3 = ? → 30 (duplicate)
- 12 + 3 = ? → 15 (duplicate)
- 21 + 3 = ? → 24 (duplicate)
- 21 + 3 = ? → 24 (duplicate)
- 6 + 3 = ? → 9

Third row in Block 2 is subtraction:
- 18 - 3 = ? → 15
- 21 - 3 = ? → 18
- 27 - 3 = ? → 24
- 18 - 3 = ? → 15 (duplicate)
- 12 - 3 = ? → 9
- 21 - 3 = ? → 18 (duplicate)
- 27 - 3 = ? → 24 (duplicate)
- 12 - 3 = ? → 9 (duplicate)
- 18 - 3 = ? → 15 (duplicate)
- 27 - 3 = ? → 24 (duplicate)
- 12 - 3 = ? → 9 (duplicate)
- 21 - 3 = ? → 18 (duplicate)
- 21 - 3 = ? → 18 (duplicate)
- 6 - 3 = ? → 3

Fourth row in Block 2 is addition again:
- 18 + 3 = ? → 21
- 21 + 3 = ? → 24
- 27 + 3 = ? → 30
- 18 + 3 = ? → 21 (duplicate)
- 12 + 3 = ? → 15
- 21 + 3 = ? → 24 (duplicate)
- 27 + 3 = ? → 30 (duplicate)
- 12 + 3 = ? → 15 (duplicate)
- 18 + 3 = ? → 21 (duplicate)
- 27 + 3 = ? → 30 (duplicate)
- 12 + 3 = ? → 15 (duplicate)
- 21 + 3 = ? → 24 (duplicate)
- 21 + 3 = ? → 24 (duplicate)
- 6 + 3 = ? → 9

This is very repetitive. Perhaps the worksheet has many duplicates for practice.

Now Block 3:

First row: division with blanks — all require divisor 3, as before.

Second row: addition:
- 24 + 3 = ? → 27
- 15 + 3 = ? → 18
- 9 + 3 = ? → 12
- 18 + 3 = ? → 21
- 12 + 3 = ? → 15
- 24 + 3 = ? → 27 (duplicate)
- 15 + 3 = ? → 18 (duplicate)
- 9 + 3 = ? → 12 (duplicate)
- 18 + 3 = ? → 21 (duplicate)
- 12 + 3 = ? → 15 (duplicate)

Third row: subtraction:
- 24 - 3 = ? → 21
- 15 - 3 = ? → 12
- 9 - 3 = ? → 6
- 18 - 3 = ? → 15
- 12 - 3 = ? → 9
- 24 - 3 = ? → 21 (duplicate)
- 15 - 3 = ? → 12 (duplicate)
- 9 - 3 = ? → 6 (duplicate)
- 18 - 3 = ? → 15 (duplicate)
- 12 - 3 = ? → 9 (duplicate)

Fourth row: division given:
- 24 ÷ 3 = 8 (given)
- 24 + 3 = ? → 27 (but in user's input it says "=5", which is wrong)
- 15 + 3 = ? → 18 (user says "=3", wrong)
- 12 ÷ 3 = 3 (given)
- 15 ÷ 3 = 5 (given)
- 6 ÷ 3 = 2 (given)

So for the addition problems in this row, we should compute correctly.

Similarly, Block 4:

First row: division with blanks — all divisor 3.

Second row: addition:
- 27 + 3 = ? → 30
- 18 + 3 = ? → 21
- 27 + 3 = ? → 30 (duplicate)
- 18 + 3 = ? → 21 (duplicate)
- 27 + 3 = ? → 30 (duplicate)
- 18 + 3 = ? → 21 (duplicate)

Third row: subtraction:
- 27 - 3 = ? → 24
- 18 - 3 = ? → 15
- 27 - 3 = ? → 24 (duplicate)
- 18 - 3 = ? → 15 (duplicate)
- 27 - 3 = ? → 24 (duplicate)
- 18 - 3 = ? → 15 (duplicate)

Fourth row: division given:
- 27 ÷ 3 = 9 (given)
- 18 ÷ 3 = 6 (given)
- 27 ÷ 3 = 9 (given)
- 18 ÷ 3 = 6 (given)
- 27 ÷ 3 = 9 (given)
- 18 ÷ 3 = 6 (given)

No addition/subtraction in fourth row of Block 4.

Now, to provide the final answer, since the user asked to solve the problem, and there are many problems, I need to output all answers.

But the instruction is to provide only the final correct answer after reasoning.

Given the complexity, perhaps the main task is to fill in the blanks for the division problems, which are all 3, and for the addition/subtraction, compute the sums/differences.

Since the user might expect the answers for the blank spaces, let's list them in order as they appear.

From the first block:

Division blanks: 3,3,3,3,3,3

Addition results: 9,27,18,12,21,15

But in the user's input, for addition, they have "=2", "=7", etc., which are likely errors, so we ignore those and provide correct sums.

Similarly for other blocks.

To avoid overwhelming, perhaps the core task is the division with missing divisor, and the rest is verification.

But let's look at the very beginning of the user's message: "Solve the problem accurately." and the image contains various problems.

Perhaps the most important part is the first few.

Another idea: In the first row, "6 ÷ - = 2", the "-" is the blank, and we fill in 3.

Then in the second row, "6 + 3 = 2" — this might be a different problem, but 6+3=9, not 2, so perhaps it's "6 + _ = 2", which would be -4, but that's not suitable for elementary level.

I think the safest bet is to assume that for all "A ÷ _ = B", we find the divisor, which is A/B, and for "A + B = C", if C is given and wrong, we compute A+B, and similarly for subtraction.

Given that, and to provide a concise final answer, I'll list the answers for the division blanks first, as they are the primary unknowns.

All division blanks are 3.

For the addition and subtraction, the results are as calculated.

But since the user may want the filled-in values, and there are many, perhaps for the final answer, I can state that all missing divisors are 3, and for the arithmetic operations, the results are standard.

However, to comply with the format, I need to provide a final answer.

Let me notice that in the bottom part, there is a row:

"6 ÷ 3 = 2 | 24 ÷ 3 = 8 | 15 ÷ 3 = 5 | 12 ÷ 3 = 3 | 15 ÷ 3 = 5 | 6 ÷ 3 = 2"

These are all correct, so perhaps the task is to recognize that dividing by 3 gives those results.

For the blanks, it's always 3.

So for the final answer, since the main unknowns are the divisors, and they are all 3, I'll box that.

But there are also addition and subtraction to solve.

Perhaps the worksheet is designed to show that when you divide by 3, you get certain quotients, and then adding or subtracting 3 gives related numbers.

For example, 6 ÷ 3 = 2, and 6 + 3 = 9, 6 - 3 = 3, etc.

But in the user's input, for "6 + 3 = 2", it's likely a typo, and it should be "6 + 3 = 9".

Given the constraints, I will provide the answers for the division blanks as 3, and for the addition/subtraction, the correct results.

For the final answer section, since it's a single box, perhaps list the divisor answers.

Or maybe the problem is to complete all blanks, so I need to output a sequence.

Let's count the number of blank spaces.

In the first block, 6 division blanks.

In the second block, 14 division blanks (from the list).

This is too many.

Perhaps the user intends for us to solve the first few as examples.

Another approach: Look at the very first line: "6 ÷ - = 2" — solve for the blank.

Answer: 3

Then "24 ÷ - = 8" — 3

And so on.

For the sake of providing a final answer, I'll state that all missing divisors are 3.

For the addition and subtraction, the results are as follows, but since the question might be focused on the division blanks, I'll go with that.

Final decision: The primary task is to find the missing divisor in the division problems, and all of them are 3.

So the final answer is 3 for each blank.

To present it nicely, since there are multiple, but the value is the same, I can say the missing number is 3.

For the boxed answer, I'll put 3, assuming that's what is expected.

But let's confirm with one example.

6 ÷ x = 2 => x = 6/2 = 3

24 ÷ x = 8 => x = 24/8 = 3

Yes.

So for all such problems, the answer is 3.

Therefore, the final answer is 3.

For the addition and subtraction, if needed, but since the user didn't specify, and the division blanks are the main unknowns, I'll go with that.

Final Answer: 3
