🔢 Step-by-step Solutions:

We’ll go through each problem row by row.

---

#### Row 1:
1. $ 5 + 1 = 6 $ ✔
2. $ 6 + 5 = 11 $ ✔
3. $ 5 + 9 = 14 $ ✔
4. $ 6 + 9 = 15 $ ✔
5. $ 8 + 6 = 14 $ ✔
6. $ 1 + 9 = 10 $ ✔
7. $ 8 + 1 = 9 $ ✔
8. $ 3 + 4 = 7 $ ✔
9. $ 3 + 2 = 5 $ ✔

✔ All correct so far!

#### Row 2:
10. $ 6 + 2 = 8 $ ✔
11. $ 7 + 4 = 11 $ ✔
12. $ 1 + 4 = 5 $
13. $ 9 + 4 = 13 $
14. $ 9 + 8 = 17 $
15. $ 3 + 8 = 11 $
16. $ 4 + 4 = 8 $
17. $ 2 + 1 = 3 $
18. $ 1 + 7 = 8 $

Now fill in the blanks:
- $ 1 + 4 = \boxed{5} $
- $ 9 + 4 = \boxed{13} $
- $ 9 + 8 = \boxed{17} $
- $ 3 + 8 = \boxed{11} $
- $ 4 + 4 = \boxed{8} $
- $ 2 + 1 = \boxed{3} $
- $ 1 + 7 = \boxed{8} $

#### Row 3:
19. $ 7 + 3 = 10 $
20. $ 1 + 6 = 7 $
21. $ 2 + 8 = 10 $
22. $ 6 + 7 = 13 $
23. $ 2 + 9 = 11 $
24. $ 4 + 1 = 5 $
25. $ 9 + 5 = 14 $
26. $ 5 + 2 = 7 $
27. $ 2 + 3 = 5 $

Now fill in:
- $ 7 + 3 = \boxed{10} $
- $ 1 + 6 = \boxed{7} $
- $ 2 + 8 = \boxed{10} $
- $ 6 + 7 = \boxed{13} $
- $ 2 + 9 = \boxed{11} $
- $ 4 + 1 = \boxed{5} $
- $ 9 + 5 = \boxed{14} $
- $ 5 + 2 = \boxed{7} $
- $ 2 + 3 = \boxed{5} $

📝 Explanation of Regrouping:

Regrouping (or carrying) happens when the sum of two digits is 10 or more.

For example:
- $ 9 + 8 = 17 $: Write down 7, carry over 1 to the tens place.
- But since these are single-digit additions, we just write the full number (e.g., 17), and no actual "regrouping" into columns is needed here — it's just practice for understanding larger sums.

In this worksheet, all problems are single-digit additions, so the answers can be written directly. However, some results (like 11, 13, 14, etc.) involve two digits, which helps students recognize when a ten has been formed.

✔ Total Score:

There are 27 problems in total.

Let’s check how many were filled in:

- Row 1: 9 problems → already solved (all correct)
- Row 2: 9 problems → 7 blanks to fill (we did them)
- Row 3: 9 problems → 9 blanks to fill (we did them)

So, total = 27 problems

All answers are now correct.

> ⭐ Score: 27/27 (but the max score listed is /81 — that seems like a typo or mislabeling.)

Wait! The worksheet says Score: ___ /81, but there are only 27 problems. That suggests either:
- Each problem is worth 3 points (unlikely),
- Or it's a mistake in the header.

But since each addition is a single problem, likely the correct maximum score is 27.

So if Peter answered all correctly, his score should be:

> ✔ 27 / 27 (not 81)

Possibly the 81 is a typo or meant for another version of the worksheet.

✔ Final Answer:

All problems solved correctly.

The completed sums are:

```
Row 1: 6, 11, 14, 15, 14, 10, 9, 7, 5
Row 2: 8, 11, 5, 13, 17, 11, 8, 3, 8
Row 3: 10, 7, 10, 13, 11, 5, 14, 7, 5
```

✔ Score: 27 / 27 (likely intended as 27, not 81)
