Mixed addition and subtraction math problems for practice.

Let’s solve each problem step by step. We’ll go row by row, column by column, and do the addition or subtraction carefully.

---

First Row:

1. 33 + 18 =
30 + 10 = 40
3 + 8 = 11
40 + 11 = 51

2. 32 - 14 =
32 - 10 = 22
22 - 4 = 18

3. 58 - 35 =
58 - 30 = 28
28 - 5 = 23

---

Second Row:

4. 12 + 29 =
10 + 20 = 30
2 + 9 = 11
30 + 11 = 41

5. 78 - 59 =
78 - 50 = 28
28 - 9 = 19

6. 25 + 37 =
20 + 30 = 50
5 + 7 = 12
50 + 12 = 62

7. 54 - 18 =
54 - 10 = 44
44 - 8 = 36

8. 25 + 25 =
20 + 20 = 40
5 + 5 = 10
40 + 10 = 50

---

Third Row:

9. 66 - 27 =
66 - 20 = 46
46 - 7 = 39

10. 33 + 27 =
30 + 20 = 50
3 + 7 = 10
50 + 10 = 60

11. 38 - 12 =
38 - 10 = 28
28 - 2 = 26

12. 36 - 46 → Wait! This is 36 minus 46? That would be negative. But looking again — it says “36 - 46”? Let me check the image again... Actually, in the original, it's written as:

> 36
> - 46

That can’t be right for a basic worksheet — maybe it’s a typo? Or perhaps I misread. Let me double-check the layout.

Actually, looking at the structure, each column has two numbers with an operation between them. So for that cell, it’s:

36 - 46 — but that gives -10, which is unusual for this level. Maybe it’s supposed to be 46 - 36? Let me check the position.

Wait — let’s look at the full grid again from your description:

The third row is:

66 33 38 36 63
-27 +27 -12 -46 -39

So yes, 36 - 46 = -10

But since this is likely meant for elementary students, maybe it’s a mistake? Or perhaps we just compute it as is.

I’ll proceed with correct math: 36 - 46 = -10

13. 63 - 39 =
63 - 30 = 33
33 - 9 = 24

---

Fourth Row:

14. 17 + 79 =
10 + 70 = 80
7 + 9 = 16
80 + 16 = 96

15. 63 - 25 =
63 - 20 = 43
43 - 5 = 38

16. 36 + 28 =
30 + 20 = 50
6 + 8 = 14
50 + 14 = 64

17. 65 - 37 =
65 - 30 = 35
35 - 7 = 28

18. 25 + 46 =
20 + 40 = 60
5 + 6 = 11
60 + 11 = 71

---

Fifth Row:

19. 92 - 59 =
92 - 50 = 42
42 - 9 = 33

20. 39 + 41 =
30 + 40 = 70
9 + 1 = 10
70 + 10 = 80

21. 48 - 34 =
48 - 30 = 18
18 - 4 = 14

22. 55 - 39 =
55 - 30 = 25
25 - 9 = 16

23. 73 - 58 =
73 - 50 = 23
23 - 8 = 15

---

Sixth Row:

24. 25 + 47 =
20 + 40 = 60
5 + 7 = 12
60 + 12 = 72

25. 70 - 49 =
70 - 40 = 30
30 - 9 = 21

26. 26 + 69 =
20 + 60 = 80
6 + 9 = 15
80 + 15 = 95

27. 71 - 19 =
71 - 10 = 61
61 - 9 = 52

28. 28 + 44 =
20 + 40 = 60
8 + 4 = 12
60 + 12 = 72

---

Now, let’s list all answers in order (left to right, top to bottom):

Row 1: 51, 18, 23
Row 2: 41, 19, 62, 36, 50
Row 3: 39, 60, 26, -10, 24 ← Note: -10 is correct mathematically, though unusual
Row 4: 96, 38, 64, 28, 71
Row 5: 33, 80, 14, 16, 15
Row 6: 72, 21, 95, 52, 72

Wait — let me count how many problems there are.

Looking back: The worksheet has 6 rows, but not all rows have same number of columns.

Actually, let’s map it properly based on standard layout:

Typically, these worksheets are arranged in columns. From your image description, it seems like 5 columns per row, except maybe first row?

Wait — let me recount based on your text:

You wrote:

First line after name/score:
33 32 58
+18 -14 -35 → so 3 problems

Then next line:
12 78 25 54 25
+29 -59 +37 -18 +25 → 5 problems

Then:
66 33 38 36 63
-27 +27 -12 -46 -39 → 5 problems

Then:
17 63 36 65 25
+79 -25 +28 -37 +46 → 5 problems

Then:
92 39 48 55 73
-59 +41 -34 -39 -58 → 5 problems

Then:
25 70 26 71 28
+47 -49 +69 -19 +44 → 5 problems

So total: 3 + 5 + 5 + 5 + 5 + 5 = 28 problems.

But in my earlier calculation, I did 28 items. Good.

Now, let me write the answers in the exact order they appear, left to right, top to bottom:

Problem 1: 33 + 18 = 51
Problem 2: 32 - 14 = 18
Problem 3: 58 - 35 = 23

Problem 4: 12 + 29 = 41
Problem 5: 78 - 59 = 19
Problem 6: 25 + 37 = 62
Problem 7: 54 - 18 = 36
Problem 8: 25 + 25 = 50

Problem 9: 66 - 27 = 39
Problem 10: 33 + 27 = 60
Problem 11: 38 - 12 = 26
Problem 12: 36 - 46 = -10
Problem 13: 63 - 39 = 24

Problem 14: 17 + 79 = 96
Problem 15: 63 - 25 = 38
Problem 16: 36 + 28 = 64
Problem 17: 65 - 37 = 28
Problem 18: 25 + 46 = 71

Problem 19: 92 - 59 = 33
Problem 20: 39 + 41 = 80
Problem 21: 48 - 34 = 14
Problem 22: 55 - 39 = 16
Problem 23: 73 - 58 = 15

Problem 24: 25 + 47 = 72
Problem 25: 70 - 49 = 21
Problem 26: 26 + 69 = 95
Problem 27: 71 - 19 = 52
Problem 28: 28 + 44 = 72

I think I made a small error in problem numbering earlier, but now it’s aligned.

Let me verify a few tricky ones again:

Problem 12: 36 - 46 → Yes, that’s definitely -10. If the worksheet intended 46 - 36, it would be 10, but as written, it’s 36 - 46.

In some contexts, especially if this is for young students, they might avoid negatives, so perhaps it’s a typo. But since we must solve what’s given, we’ll keep -10.

Another one: Problem 7: 54 - 18 → 54 - 10 = 44, 44 - 8 = 36 ✔️

Problem 22: 55 - 39 → 55 - 30 = 25, 25 - 9 = 16 ✔️

Problem 27: 71 - 19 → 71 - 20 = 51, then +1 because we subtracted one extra → 52 ✔️ (or 71 - 10 = 61, 61 - 9 = 52)

All seem correct.

Final Answer:
51, 18, 23, 41, 19, 62, 36, 50, 39, 60, 26, -10, 24, 96, 38, 64, 28, 71, 33, 80, 14, 16, 15, 72, 21, 95, 52, 72
