Let’s solve each addition problem step by step. Remember, we’re adding two-digit numbers and all of them require regrouping (also called “carrying”). That means when the ones column adds up to 10 or more, we carry a 1 to the tens column.

We’ll go row by row, left to right.

---

Row 1:

1. 37 + 73
Ones: 7 + 3 = 10 → write 0, carry 1
Tens: 3 + 7 + 1 (carry) = 11 → write 11
→ 110

2. 66 + 91
Ones: 6 + 1 = 7 → no carry? Wait — 6+1=7, but let’s check again: 66 + 91
Actually: 6 + 1 = 7 (ones), 6 + 9 = 15 → so total is 157? But wait — that doesn’t need regrouping in ones? Let me recalculate carefully.

Wait — maybe I misread. The problem says “all Regrouping” — so every problem should have regrouping. Let me double-check 66 + 91:

Ones: 6 + 1 = 7 → no carry? Hmm… but 66 + 91 = 157 — yes, but only the tens place regroups? Maybe the title means at least one regrouping per problem? Or perhaps I made a mistake.

Actually, looking back — maybe some problems don’t regroup in the ones, but do in the tens? But the title says “all Regrouping” — probably meaning every problem requires carrying from ones to tens.

Wait — let’s check 66 + 91 again:

66
+91
——
Ones: 6 + 1 = 7 → no carry
Tens: 6 + 9 = 15 → so we write 5 and carry 1 to hundreds? So it becomes 157 — which does involve regrouping in the tens place. But typically “regrouping” refers to carrying from ones to tens. Maybe the worksheet includes any carrying.

But to be safe, let’s just calculate all correctly regardless.

Actually, let’s proceed with accurate math for each.

I think I confused myself. Let’s just compute each sum accurately.

Let me list all problems and solve them one by one carefully.

---

Row 1:

1. 37 + 73
7 + 3 = 10 → write 0, carry 1
3 + 7 + 1 = 11 → write 11
→ 110

2. 66 + 91
6 + 1 = 7
6 + 9 = 15 → so 157
→ 157

3. 75 + 99
5 + 9 = 14 → write 4, carry 1
7 + 9 + 1 = 17 → write 17
→ 174

4. 96 + 28
6 + 8 = 14 → write 4, carry 1
9 + 2 + 1 = 12 → write 12
→ 124

5. 94 + 45
4 + 5 = 9 → no carry? Wait, 94 + 45 = 139 — tens: 9+4=13, so carry from tens? But ones didn’t carry. Again, maybe “all regrouping” means at least one carry happens. We’ll just compute correctly.

4 + 5 = 9
9 + 4 = 13 → so 139
→ 139

Wait — this one doesn’t regroup in the ones place. But the worksheet says “all Regrouping”. Maybe I misread the problems? Let me check the original image description.

Looking back at user input — the problems are written as:

First row:
37+73=
66+91=
75+99=
96+28=
94+45=

And vertically aligned below each.

For 94 + 45:
94
+ 45
——
Ones: 4+5=9 → no carry
Tens: 9+4=13 → so we write 3 and carry 1 to hundreds → 139

So technically, there is regrouping (in the tens place). Maybe the worksheet considers any carrying as “regrouping”.

To avoid confusion, I’ll just compute each sum correctly.

Let’s continue.

Row 2:

6. 55 + 79
5 + 9 = 14 → write 4, carry 1
5 + 7 + 1 = 13 → write 13
→ 134

7. 88 + 25
8 + 5 = 13 → write 3, carry 1
8 + 2 + 1 = 11 → write 11
→ 113

8. 67 + 35
7 + 5 = 12 → write 2, carry 1
6 + 3 + 1 = 10 → write 10
→ 102

9. 69 + 75
9 + 5 = 14 → write 4, carry 1
6 + 7 + 1 = 14 → write 14

5 + 5 + 1 = 11 → write 11

Row 3:

11. 83 + 83
3 + 3 = 6 → no carry? Wait, 83+83=166 — tens: 8+8=16, so carry from tens? But ones didn’t carry. Again, same issue.

Let’s compute:
3 + 3 = 6
8 + 8 = 16 → so 166
→ 166

12. 77 + 92
7 + 2 = 9
7 + 9 = 16 → 169
