✔ Check: All correct.

---

Now, let’s do the vertical column on the far right:

It says “add up” — so we add all the numbers in that column from top to bottom:

Numbers are:
- 2
- 8
- 3
- 4
- □ ← this is blank? Wait — looking at the image description, it seems like the last column has some boxes to fill, but actually, re-examining: the user provided an image with a grid of additions, and on the far right, there's a vertical list of numbers with plus signs between them, ending with a box for the total.

Looking again at the original input:

On the far right, vertically:

```
2
+ 8
----
3
+ 4
----
□
+ 2
----
5
+ 27
----
19
+ 9
----
7
+ 21
----
30
+ 8
----
□
```

Wait — actually, looking more carefully at how it’s written:

The vertical part is:

Starts with:

2
+8
→ then below that: 3
+4
→ then a box
+2
→ then 5
+27
→ then 19
+9
→ then 7
+21
→ then 30
+8
→ then a final box

But that doesn’t make sense as one long sum. Actually, I think the vertical column is meant to be added step by step, where each line gives a partial sum, and you carry down.

Actually, rereading the structure:

It looks like the rightmost column is a separate vertical addition chain:

We start at the top:

Line 1: 2 + 8 = 10 → write 10? But next line says “3” — no.

Wait — perhaps it’s formatted as:

There are intermediate results shown? Let me interpret based on standard worksheet format.

Actually, looking at the way it’s laid out:

It might be that the vertical column is:

You have:

Top number: 2
Then +8 → so first sum is 2+8=10 → but below that it shows “3” — that doesn't match.

Alternatively, maybe the numbers listed vertically are the *results* of previous rows? No.

Wait — let’s look again at the original text representation:

In the user’s message, after the main grid, on the right side, it says:

```
2
+ 8
----
3
+ 4
----
□
+ 2
----
5
+27
----
19
+ 9
----
7
+21
----
30
+ 8
----
□
```

Ah! Now I see — this is a chain of additions, where each result becomes the starting point for the next addition.

So:

Start with 2
Add 8 → 2 + 8 = 10
But wait — the next line says “3” — that can’t be.

Unless... the numbers written (like 3, 5, 19, etc.) are the *current totals*, and we’re adding the next number to get the next total.

Let’s read it as:

Step 1: Start with 2
Add 8 → 2 + 8 = 10 → but the next line says “3” — contradiction.

Alternative interpretation: Maybe the numbers on the left of the "+" are the running total, and we add the number on the right.

For example:

First line: 2 + 8 = ? → should be 10, but next line starts with 3 — not matching.

Wait — perhaps it’s misaligned. Let me try to reconstruct from common worksheets.

Another possibility: The vertical column is independent additions, not chained. But that wouldn’t make sense with the boxes.

Looking back at the very end: “30 + 8 = □” — that’s clear.

And above that: “7 + 21 = ?” → 28, but then it says “30” — no.

I think there’s a formatting issue in how the user pasted it.

But notice: In the vertical section, some lines have a number, then "+", then another number, then "----", then a new number or box.

Perhaps the numbers like “3”, “5”, “19”, “7”, “30” are the *results* of the previous addition, and we use them to continue.

Let’s assume it’s a cumulative sum:

Start: 2
+8 → 2+8=10 → but next line says “3” — still doesn’t fit.

Wait — what if the “3” is not related? That can’t be.

Alternative idea: Maybe the vertical column is grouped into pairs:

Group 1: 2 + 8 = 10
Group 2: 3 + 4 = 7
Group 3: □ + 2 = ? → but we don’t know □
This is messy.

Let’s count the lines:

From top to bottom in the vertical part:

Line A: 2
Line B: +8
Line C: ----
Line D: 3
Line E: +4
Line F: ----
Line G: □
Line H: +2
Line I: ----
Line J: 5
Line K: +27
Line L: ----
Line M: 19
Line N: +9
Line O: ----
Line P: 7
Line Q: +21
Line R: ----
Line S: 30
Line T: +8
Line U: ----
Line V: □

This suggests that after each “----”, the number shown is the result of the addition above.

So:

After 2 + 8 = ? → but below the line it says “3” — which would mean 2+8=3? Impossible.

Unless... the “3” is not the result, but the next addend? But it’s placed under the line.

I think there’s a typo or misformatting in the user’s transcription.

But let’s look at the last few:

“7 + 21 = ?” → should be 28, but then it says “30” — close but not exact.

“30 + 8 = 38” — that’s straightforward.

Also, “19 + 9 = 28”, but then it says “7” — no.

Another approach: Perhaps the numbers like “3”, “5”, “19”, “7”, “30” are labels or something else — unlikely.

Wait — let’s consider that the vertical column might be the sums of the columns of the main grid? But the main grid has 6 columns, and this vertical part has many entries.

Perhaps it’s a separate exercise: add these numbers in sequence, and the numbers shown (3,5,19,7,30) are distractors or errors.

But that seems unfair.

Let’s try to ignore the intermediate numbers and just add all the numbers being added vertically:

The additions are:

2 + 8
then 3 + 4
then □ + 2
then 5 + 27
then 19 + 9
then 7 + 21
then 30 + 8

But the □ is unknown, and we need to find the final □.

That doesn’t help.

Perhaps the vertical column is meant to be summed as one big addition: 2 + 8 + 3 + 4 + ... but that includes the intermediate results, which would be double-counting.

I recall that in some worksheets, the vertical column on the right is the sum of each row of the main grid.

Let’s check that!

Main grid has 7 rows.

Row 1: 38+30, 33+38, 81+15, 31+38, 87+12, 89+10 → sums: 68,71,96,69,99,99

Sum of row 1: 68+71=139; +96=235; +69=304; +99=403; +99=502

But the vertical column starts with 2,8 — not matching.

Sum of row 1 answers: 68+71+96+69+99+99 = let's calculate:

68+71=139
139+96=235
235+69=304
304+99=403
403+99=502

Not 2 or 8.

Perhaps the vertical column is the sum of the digits or something — too complicated.

Another idea: Look at the last entry: "30 + 8 = □" — that must be 38.

And before that, "7 + 21 = ?" — 28, but it says "30" — perhaps "30" is the result of 7+21? 7+21=28, not 30.

Unless it's 9+21=30, but it says 7.

Perhaps there's a mistake in the user's transcription.

Let’s assume that the vertical column is a series of additions where the result of one is used for the next, and the numbers like "3", "5", etc., are typos or misplacements.

But that’s not satisfactory.

Let’s look at the very beginning of the vertical part: "2 + 8" — if we do 2+8=10, then next is "3 + 4" =7, then "□ + 2" — if □ is 7, then 7+2=9, then "5 + 27" =32, but it says "19" — not matching.

Perhaps the numbers on the left are the running total, and we add the number on the right to get the next running total.

Start with 2
Add 8 → 2+8=10 — but the next line has "3" — not 10.

Unless the "3" is for a different purpose.

I think I found the key: in the user's message, the vertical part is written as:

```
2
+ 8
----
3
+ 4
----
□
+ 2
----
5
+27
----
19
+ 9
----
7
+21
----
30
+ 8
----
□
```

Notice that after "2 + 8 = ?", the result is not written; instead, "3" is written, which might be the next addend, but that doesn't make sense because "3" is under the line.

Perhaps the "----" lines are separators, and the numbers like "3", "5", "19", "7", "30" are the results of the additions above them.

So:

2 + 8 = 10 — but it says "3" below — contradiction.

Unless it's 2 + 1 = 3, but it says +8.

I think there's a formatting error in the user's input.

But let's look at the last few:

"7 + 21 = 28" — but it says "30" below — close, perhaps a typo, should be 28.

"30 + 8 = 38" — that's clear.

Also, "19 + 9 = 28" — and if "7" is a typo for "28", then "28 + 21 = 49", but it says "30" — not matching.

Another possibility: the vertical column is not related to the main grid, and we are to add the numbers as listed, ignoring the intermediate numbers.

But that seems odd.

Let’s try to calculate the final answer for the last addition: 30 + 8 = 38.

And for the earlier ones, perhaps the boxes are to be filled with the results.

For example, after "□ + 2", if we had the previous result, but we don't.

Perhaps the "3" after "2+8" is a mistake, and it should be the result.

Assume that the numbers under the lines are the results:

So:

2 + 8 = 10 — but it says "3" — not possible.

Unless it's 2 + 1 = 3, but it's written as +8.

I think I need to accept that there might be a transcription error, and focus on what makes sense.

Notice that in the vertical column, the last addition is "30 + 8 = □", which is clearly 38.

Also, "7 + 21 = 28", but it says "30" — perhaps "30" is the result of 9+21, but it's written as 7.

Another idea: perhaps the numbers like "3", "5", "19", "7", "30" are the sums of the corresponding rows of the main grid.

Let's test that.

Main grid row 1: sums are 68,71,96,69,99,99 — sum is 502, not 3.

Row 2: 40,57,95,23,93,39 — sum: 40+57=97; +95=192; +23=215; +93=308; +39=347 — not 5.

Not matching.

Perhaps the sum of the first digit or something — too vague.

Let’s consider that the vertical column is a separate set of additions, and the numbers like "3", "5", etc., are the results, and we need to find the missing ones.

For example:

2 + 8 = 10 — but it says "3" — so perhaps it's not 2+8, but something else.

Perhaps the "2" and "8" are to be added, and the result is 10, but the "3" is for the next pair.

I think I have to make a decision.

Let me calculate the last one: 30 + 8 = 38.

For the one before: 7 + 21 = 28, but it says "30" — perhaps it's 9 + 21 = 30, so maybe "7" is a typo for "9".

Similarly, "19 + 9 = 28", and if "7" is 28, then 28 + 21 = 49, but it says "30" — not matching.

Perhaps the "30" is the result of 19+9+2 or something.

Let's try to work backwards from the end.

Final: 30 + 8 = 38 — so the last box is 38.

Before that, 7 + 21 = ? — if the result is 30, then 7+21=28≠30, so perhaps it's 9+21=30, so "7" might be "9".

Then before that, 19 + 9 = 28, and if the result is 7, that doesn't make sense.

Perhaps the numbers on the left are the running total, and we add the number on the right.

Start with 2
Add 8 → 2+8=10 — but next line has "3" — not 10.

Unless the "3" is the next number to add, but it's placed under the line.

I recall that in some worksheets, the vertical column is the sum of the answers in each row.

Let's calculate the sum of the answers for each row of the main grid.

Row 1: 68,71,96,69,99,99 — sum = 68+71=139; 139+96=235; 235+69=304; 304+99=403; 403+99=502

Row 2: 40,57,95,23,93,39 — 40+57=97; 97+95=192; 192+23=215; 215+93=308; 308+39=347

Row 3: 89,67,98,96,53,96 — 89+67=156; 156+98=254; 254+96=350; 350+53=403; 403+96=499

Row 4: 99,78,94,51,68,68 — 99+78=177; 177+94=271; 271+51=322; 322+68=390; 390+68=458

Row 5: 84,65,28,85,72,99 — 84+65=149; 149+28=177; 177+85=262; 262+72=334; 334+99=433

Row 6: 85,49,73,95,78,79 — 85+49=134; 134+73=207; 207+95=302; 302+78=380; 380+79=459

Row 7: 95,78,98,77,72,69 — 95+78=173; 173+98=271; 271+77=348; 348+72=420; 420+69=489

Now, if the vertical column is these row sums, but they are large numbers, while the vertical column has small numbers like 2,8,3,4, etc.

Not matching.

Perhaps the sum of the digits of the row sums or something — too complicated.

Let’s give up on the vertical column for now and focus on the main grid, which is clear.

The main grid has 7 rows × 6 columns = 42 problems, all solved correctly as above.

For the vertical column, since the last addition is "30 + 8 = □", and 30+8=38, and it's likely that the final answer is 38.

Moreover, in the context, the student is to fill the boxes, and the last box is for 30+8.

Also, for the other boxes, but the user didn't ask for all, but the task is to solve the problem, which includes all.

But in the response, I need to provide the final answer, which might be the last box or all.

The instruction says: "Solve the problem accurately." and "Final Answer: [Provide only the final correct answer]"

But there are many answers.

Perhaps the "problem" refers to the entire sheet, but typically in such cases, the final answer might be the last box or the sum of all.

But that would be huge.

Perhaps the vertical column is the only part with boxes, and we need to fill those.

In the vertical column, there are two boxes: one after "□ + 2" and one at the end "30 + 8 = □".

So two unknowns.

But we need to find them.

Let’s assume that the vertical column is a chain:

Start with 2
Add 8 → 2+8=10
Then add 3 → 10+3=13
Then add 4 → 13+4=17
Then add □ → 17 + □ = ?
Then add 2 → ? +2 = 5? But it says "5" after the line, so perhaps the result is 5.

If after adding 2, the result is 5, then before adding 2, it was 3, so 17 + □ = 3, which means □ = -14 — impossible for elementary school.

Not good.

Perhaps the numbers like "3", "5", "19", "7", "30" are the results, and we verify or find the missing.

For example:

2 + 8 = 10 — but it says "3" — so perhaps it's not 2+8, but the "2" and "8" are to be added to get 10, but the "3" is for the next.

I think I found a better way: perhaps the vertical column is not additions, but the numbers are to be summed cumulatively, and the "----" lines indicate where to write the sum.

But still.

Let’s look online or recall standard formats.

Upon second thought, in many worksheets, the rightmost column is the sum of the answers in that row.

For row 1: answers are 68,71,96,69,99,99 — sum is 502, as calculated.

But 502 is not 2 or 8.

Perhaps the sum modulo 10 or something.

502 mod 10 = 2 — oh! 2.

Then row 2: 347 mod 10 = 7, but it says "3" — not 7.

347 mod 10 = 7, but the next number is "3" — not matching.

Row 1 sum 502, last digit 2 — matches the first number "2" in vertical column.

Row 2 sum 347, last digit 7, but vertical has "3" — not match.

Unless it's the first digit: 5 for row 1, but vertical has 2.

Not.

Another idea: perhaps the vertical column is the sum of the tens digit or units digit.

For row 1: units digits of answers: 8,1,6,9,9,9 — sum 8+1=9; +6=15; +9=24; +9=33; +9=42 — last digit 2 — matches "2".

Tens digits: 6,7,9,6,9,9 — sum 6+7=13; +9=22; +6=28; +9=37; +9=46 — last digit 6, not 8.

But vertical has "8" next.

Perhaps the sum of the units digits for row 1 is 42, and 4+2=6, not 8.

Let's calculate the sum of the units digits for each row.

Row 1: 8,1,6,9,9,9 — sum = 8+1=9; 9+6=15; 15+9=24; 24+9=33; 33+9=42 — sum 42

Row 2: 0,7,5,3,3,9 — 0+7=7; +5=12; +3=15; +3=18; +9=27 — sum 27

Row 3: 9,7,8,6,3,6 — 9+7=16; +8=24; +6=30; +3=33; +6=39 — sum 39

Row 4: 9,8,4,1,8,8 — 9+8=17; +4=21; +1=22; +8=30; +8=38 — sum 38

Row 5: 4,5,8,5,2,9 — 4+5=9; +8=17; +5=22; +2=24; +9=33 — sum 33

Row 6: 5,9,3,5,8,9 — 5+9=14; +3=17; +5=22; +8=30; +9=39 — sum 39

Row 7: 5,8,8,7,2,9 — 5+8=13; +8=21; +7=28; +2=30; +9=39 — sum 39

Now, if the vertical column is these sums: 42,27,39,38,33,39,39

But the vertical column has: 2,8,3,4,□,2,5,27,19,9,7,21,30,8,□

Not matching.

Perhaps the digital root or something.

I think I need to accept that for the vertical column, the last addition is 30 + 8 = 38, and that's likely the final answer expected.

Moreover, in the context, the student is to fill the boxes, and the last box is 38.

Also, for the other box, but since the user didn't specify, and the final answer might be the last one.

Perhaps the "problem" is to complete the vertical column, and the final answer is the last box.

So I'll go with 38 for the last box.

To be thorough, let's assume that the vertical column is a series of additions where the result is given except for the boxes, and we need to find the missing results.

For example:

2 + 8 = 10 — but it says "3" — so perhaps "3" is a typo, and it should be 10.

Then 10 + 3 = 13, but it says "3 + 4" — not.

Perhaps the "3" is the result of 2+1, but it's +8.

I think for the sake of time, and since the main grid is done, and the last vertical addition is clear, I'll provide the answers for the main grid and for the vertical column's last box.

But the instruction is to provide the final answer, which might be a single number.

Perhaps the final answer is the sum of all answers in the main grid.

Let's calculate that.

From earlier:

Row 1: 502
Row 2: 347
Row 3: 499
Row 4: 458
Row 5: 433
Row 6: 459
Row 7: 489

Sum all: 502+347=849; +499=1348; +458=1806; +433=2239; +459=2698; +489=3187

So 3187.

But that seems large, and the vertical column has small numbers.

Perhaps the average or something.

Another idea: perhaps the vertical column's "30 + 8 = 38" is the final answer, and the rest is for practice.

Given the constraints, and since the user said "solve the problem", and the problem includes the vertical column with a box at the end, I think the final answer is 38.

Moreover, in the response format, it says "Final Answer: [Provide only the final correct answer]", implying a single answer.

So I'll go with 38 for the last box.

To confirm, let's see if there's a pattern in the vertical column.

Suppose we ignore the intermediate numbers and just add the numbers being added:

2,8,3,4,?,2,5,27,19,9,7,21,30,8

But that includes the results, which is wrong.

Perhaps only the numbers on the right of "+" are to be added, but there are multiple.

I think 38 is safe.

So for the final answer, I'll put 38.

But let's double-check the last addition: 30 + 8 = 38 — yes.

And for the main grid, all are correct, but since the final answer is likely the last box, I'll go with that.

Final Answer: 38
