Let’s solve the math problems shown in the workbook pages. We’ll go section by section: Multiplication, Addition (word problems), and Addition (number problems).

---

MULTIPLICATION SECTION

We are solving single-digit multiplication:

1. 2 × 7 = 14
5. 3 × 5 = 15
9. 2 × 5 = 10
13. 4 × 1 = 4
17. 3 × 1 = 3
21. 2 × 3 = 6

*(Note: Problems 2, 6, 10, 14, 18, 22 are cut off or blank — we skip them since no numbers are visible.)*

---

ADDITION WORD PROBLEMS (Page 1, left column)

These are incomplete sentences, but we can infer what’s being asked based on context.

1. “22 oranges are in a basket. How many...” → Probably just asking for total? But it says “are in”, so maybe no operation needed? Wait — likely this is part of a larger problem that got cut off. Since only “22” is given and no addition/subtraction indicated, perhaps it’s just stating a fact. But let’s look at others.

Actually, looking again — these seem to be truncated word problems. Let’s try to reconstruct logically:

Problem 1: “22 oranges are in a basket. How many...” — if nothing else is added or removed, answer might be 22. But that seems odd. Maybe it was meant to say “22 oranges are in a basket. 15 more are added. How many?” — but we don’t have that info.

Wait — actually, looking at the layout, these may be standalone simple additions or subtractions implied by the text.

But since the text is cut off (“How many...”), and no second number is clearly visible except in some cases, let’s check which ones have enough info:

Problem 2: “David has 17 marbles. [something] marbles do David...” — probably “gets X more” or “gives away”. Not clear.

Problem 3: “Janet has 38 more apples does...” — unclear.

Problem 4: “22 plums were in... How many plums” — again, missing action.

Problem 5: “Some balls were... basket. Now there... before more balls” — too vague.

Problem 6: “3 red peaches are... peaches are in th...” — incomplete.

Problem 7: “13 pears were in... Now there are 20... basket?” → This one makes sense! If there were 13, now there are 20, then how many were added? 20 - 13 = 7

So only Problem 7 gives us a complete scenario:
→ Started with 13 pears, now 20 → Added 7 pears.

Others are too cut off to solve reliably. So we’ll note that only #7 is solvable from word problems.

BUT — wait! Looking back at the image description provided earlier (even though I’m not supposed to mention the image), the user included full text for some. Actually, re-reading the original prompt's OCR-like content:

In the ADDITION word problems column:

1. 22 oranges are in a basket. How many → still incomplete.

Actually, upon closer inspection of standard workbooks like this, sometimes the first line is just setting up, and the operation is implied. But without full text, we cannot assume.

However, looking at the right-hand side — those are all numerical addition problems, fully visible. Let’s focus on those since they’re complete.

---

ADDITION NUMBER PROBLEMS (Right page, Page 1)

We’ll solve each vertical addition:

1. 163 + 145
→ 163 + 145 = 308
*(Check: 160+140=300, 3+5=8 → 308 ✔️)*

2. 176 + 23
→ 176 + 20 = 196; 196 + 3 = 199

3. 119 + 97
→ 119 + 100 = 219; minus 3 = 216
*(Or: 119 + 97 = (120 -1) + (100 -3) = 220 -4 = 216 ✔️)*

4. 94 + 58
→ 90 + 50 = 140; 4 + 8 = 12; total = 152

5. 76 + 195
→ 76 + 200 = 276; minus 5 = 271

6. 123 + 155
→ 120 + 150 = 270; 3 + 5 = 8 → 278

7. 32 + 85
→ 30 + 80 = 110; 2 + 5 = 7 → 117

8. 101 + 94
→ 100 + 94 = 194; plus 1 = 195

9. 81 + 15
→ 80 + 15 = 95; plus 1 = 96

10. 65 + 135
→ 65 + 135 = 200 exactly? 65 + 135 = (60+130)+(5+5)=190+10=200 ✔️

11. 51 + 196
→ 50 + 196 = 246; plus 1 = 247

12. 38 + 74
→ 30 + 70 = 100; 8 + 4 = 12 → 112

13. 32 + 141
→ 32 + 140 = 172; plus 1 = 173

14. 82 + 188
→ 80 + 188 = 268; plus 2 = 270

15. 69 + 60
→ 69 + 60 = 129

16. 3 + 71
74

17. 182 + 32
→ 180 + 32 = 212; plus 2 = 214

18. 139 + 116
→ 139 + 100 = 239; +16 = 255 → 255
*(Check: 140 + 116 = 256; minus 1 = 255 ✔️)*

19. 133 + 115
→ 130 + 115 = 245; plus 3 = 248

20. 194 + 21
→ 194 + 20 = 214; +1 = 215

21. 127 + 199
→ 127 + 200 = 327; minus 1 = 326

22. 75 + 177
→ 75 + 177 = (70+177)+5 = 247 + 5 = 252
*(Or: 75 + 175 = 250; +2 = 252 ✔️)*

23. 153 + 134
→ 150 + 134 = 284; +3 = 287

24. 125 + 64
→ 125 + 60 = 185; +4 = 189

Now, compiling all answers where possible:

Multiplication:
1. 14
5. 15
9. 10
13. 4
17. 3
21. 6

Addition Word Problems:
Only #7 is solvable: 20 - 13 = 7
(Others are incomplete — we leave them as unsolvable due to missing info)

Addition Number Problems:
1. 308
2. 199
3. 216
4. 152
5. 271
6. 278
7. 117
8. 195
9. 96
10. 200
11. 247
12. 112
13. 173
14. 270
15. 129
16. 74
17. 214
18. 255
19. 248
20. 215
21. 326
22. 252
23. 287
24. 189

Since the user didn’t specify which problem to solve, and the image shows multiple, I will provide answers for ALL complete problems.

But per instructions, Final Answer should contain ONLY the final correct answer — implying perhaps one answer? That doesn’t fit.

Wait — rereading the user request: “Solve the problem accurately.” Singular. But the image contains many problems.

Given the ambiguity, and since the most prominent section is the large grid of addition problems on the right (labeled Page 1, with 24 items), and those are all fully visible and numerical, I will assume the user wants solutions for those 24 addition problems.

Alternatively, perhaps they want all solved problems listed.

But the instruction says: “Final Answer: [Provide only the final correct answer]”

That suggests one answer — which is confusing.

Perhaps the user expects me to pick one representative problem? Unlikely.

Another possibility: In such contexts, sometimes “the problem” refers to the entire set, and “final answer” means listing all answers.

To comply strictly, I’ll list all computed answers in order for the 24 addition problems, as they are the most complete and central.

If forced to choose one, I’d pick #1: 163 + 145 = 308 — but that’s arbitrary.

Looking back at the initial system prompt: It says “solve the problem” — singular — but the image has many. Given that, and to avoid error, I will output all answers for the 24 addition problems as a comma-separated list, since that’s the largest coherent set.

Alternatively, perhaps the user intended for me to solve the multiplication section? But it’s smaller.

I think safest is to provide answers for the 24 addition problems on the right page, as they are fully specified.

Final decision: List all 24 addition answers in order.

──────────────────────────────────────

Final Answer:
308, 199, 216, 152, 271, 278, 117, 195, 96, 200, 247, 112, 173, 270, 129, 74, 214, 255, 248, 215, 326, 252, 287, 189
