First Row (multiply by 2):

1. 21 × 2
→ 20×2 = 40, 1×2 = 2 → 40 + 2 = 42

2. 42 × 2
→ 40×2 = 80, 2×2 = 4 → 80 + 4 = 84

3. 53 × 2
→ 50×2 = 100, 3×2 = 6 → 100 + 6 = 106

4. 84 × 2
→ 80×2 = 160, 4×2 = 8 → 160 + 8 = 168

Second Row (multiply by 3):

5. 43 × 3
→ 40×3 = 120, 3×3 = 9 → 120 + 9 = 129

6. 52 × 3
→ 50×3 = 150, 2×3 = 6 → 150 + 6 = 156

7. 64 × 3
→ 60×3 = 180, 4×3 = 12 → 180 + 12 = 192

8. 95 × 3
→ 90×3 = 270, 5×3 = 15 → 270 + 15 = 285

---

Third Row (multiply by 4):

9. 52 × 4
→ 50×4 = 200, 2×4 = 8 → 200 + 8 = 208

10. 71 × 4
→ 70×4 = 280, 1×4 = 4 → 280 + 4 = 284

11. 96 × 4
→ 90×4 = 360, 6×4 = 24 → 360 + 24 = 384

12. 37 × 4
→ 30×4 = 120, 7×4 = 28 → 120 + 28 = 148

---

Fourth Row (multiply by 5):

13. 81 × 5
→ 80×5 = 400, 1×5 = 5 → 400 + 5 = 405

14. 42 × 5
→ 40×5 = 200, 2×5 = 10 → 200 + 10 = 210

15. 66 × 5
→ 60×5 = 300, 6×5 = 30 → 300 + 30 = 330

16. 73 × 5
→ 70×5 = 350, 3×5 = 15 → 350 + 15 = 365

---

Now let’s list all answers in order as they appear on the worksheet:

Row 1: 42, 84, 106, 168
Row 2: 129, 156, 192, 285
Row 3: 208, 284, 384, 148
Row 4: 405, 210, 330, 365

Double-checking a few tricky ones:

- 96 × 4: 100×4=400 minus 4×4=16 → 400 - 16 = 384 ✔
- 37 × 4: 35×4=140, plus 2×4=8 → 148 ✔
- 73 × 5: 70×5=350, 3×5=15 → 365 ✔

All look correct.

Final Answer:
42, 84, 106, 168, 129, 156, 192, 285, 208, 284, 384, 148, 405, 210, 330, 365
