3 Digit Addition and Subtraction Worksheets - Free Printable

Since I can't view or access uploaded images directly, I can't see the specific content of your image. However, based on your description — "I uploaded an image with a task, solve the problem and explain the solution" — and the text you've provided, it looks like you're referring to a 3-digit addition and subtraction worksheet.

Let me help you solve each problem listed in the worksheet below:

#### Subtraction Problems (not explicitly labeled, but likely next):

But wait — looking at the instructions:
> "Circle the question with the greatest total and the question with the smallest difference."

This suggests that some problems are subtraction, and we need to find:
- The addition problem with the greatest sum
- The subtraction problem with the smallest difference

However, only addition problems are listed above (problems 1–20). So perhaps the last few problems are subtraction?

Let’s recheck:
You said “addition and subtraction sheet,” so likely some of the problems are subtraction.

But in your text, all 20 problems appear to be addition.

Wait — perhaps the subtraction problems were meant to be included but weren’t copied? Or maybe they’re hidden?

Alternatively, maybe all are addition, and the instruction is just asking to:
- Circle the addition problem with the greatest total
- And circle the addition problem with the smallest total (but it says "difference", which implies subtraction)

Hmm.

Let’s analyze what’s possible.

---

Step 1: Find the greatest total among the addition problems

We already computed the sums:

| Problem | Sum |
|--------|-----|
| 1 | 669 |
| 2 | 984 |
| 3 | 811 |
| 4 | 1167 |
| 5 | 894 |
| 6 | 1044 |
| 7 | 797 |
| 8 | 909 |
| 9 | 1307 |
| 10 | 435 |
| 11 | 659 |
| 12 | 679 |
| 13 | 645 |
| 14 | 827 |
| 15 | 1300 |
| 16 | 596 |
| 17 | 1023 |
| 18 | 1139 |
| 19 | 660 |
| 20 | 958 |

Now find the largest sum:
→ Problem 9: 956 + 351 = 1307 ← Greatest total

Smallest sum:
→ Problem 10: 374 + 61 = 435 ← Smallest total

But the instruction says:
> "Circle the question with the greatest total and the question with the smallest difference"

Ah! So there must be subtraction problems involved.

But in your list, all 20 are additions.

Possibility: Maybe the last 10 are subtraction?

Let’s assume that problems 11–20 are subtraction, as sometimes worksheets alternate.

But the numbers don’t look like subtraction — for example:

11) 527 + 132 → clearly addition.

So unless the operation signs were missing, we can’t tell.

Wait — let's check if any of the problems could be subtraction.

But the format shows `+` between the numbers.

Unless the worksheet has both, and the `+` was not copied correctly?

Alternatively, perhaps the instruction is misworded, or you meant to include subtraction problems.

But since only addition is shown, I’ll assume that the "smallest difference" part refers to the smallest sum (maybe a typo), or perhaps you intended to include subtraction problems.

But since none are visible, let’s suppose that the intended meaning is:

> Circle the addition problem with the greatest total and the smallest total.

Then:
- Greatest total: Problem 9 → 956 + 351 = 1307
- Smallest total: Problem 10 → 374 + 61 = 435

But again, "difference" implies subtraction.

So here's a possibility: Perhaps the worksheet has both addition and subtraction, and you only pasted the addition part.

For example, maybe the subtraction problems are like:

11) 527 – 132 = ?
12) 602 – 77 = ?
etc.

But without seeing them, I can’t compute.

Best Guess Based on Given Data:

Assuming the only operations are addition, and the instruction has a typo (should be “smallest total” instead of “smallest difference”), then:

✔ Greatest total: Problem 9 → 956 + 351 = 1307
✔ Smallest total: Problem 10 → 374 + 61 = 435

If the worksheet does have subtraction problems, please provide them or clarify.

---

Final Answer:

> Circle Problem 9 (956 + 351 = 1307) for the greatest total.
> Circle Problem 10 (374 + 61 = 435) for the smallest total (assuming "difference" is a mistake).

If subtraction problems exist, please share them so I can identify the one with the smallest difference.
