Multiplication Problems and Solutions:

#### Row 1:
1. \( 23 \times 23 = 529 \)
2. \( 20 \times 17 = 340 \)
3. \( 57 \times 18 = 1026 \)
4. \( 19 \times 44 = 836 \)
5. \( 14 \times 45 = 630 \)
6. \( 49 \times 54 = 2646 \)

#### Row 2:
7. \( 33 \times 72 = 2376 \)
8. \( 34 \times 32 = 1088 \)
9. \( 17 \times 87 = 1479 \)
10. \( 54 \times 50 = 2700 \)
11. \( 77 \times 77 = 5929 \)
12. \( 57 \times 84 = 4788 \)

#### Row 3:
13. \( 14 \times 42 = 588 \)
14. \( 18 \times 65 = 1170 \)
15. \( 74 \times 74 = 5476 \)
16. \( 87 \times 39 = 3393 \)
17. \( 27 \times 74 = 2000 - 18 = 1982 \) → Wait, let's calculate:
\( 27 \times 74 = (20 + 7) \times 74 = 20×74 + 7×74 = 1480 + 518 = 1998 \)
18. \( 57 \times 28 = 1596 \)

#### Row 4:
19. \( 73 \times 78 = ? \)
\( 73 \times 78 = (70+3)(70+8) = 70×70 + 70×8 + 3×70 + 3×8 = 4900 + 560 + 210 + 24 = 5694 \)
20. \( 81 \times 79 = ? \)
\( 81 × 79 = (80+1)(80-1) = 80² - 1² = 6400 - 1 = 6399 \)
21. \( 24 \times 42 = 1008 \)
22. \( 55 \times 57 = ? \)
\( 55 × 57 = (50+5)(50+7) = 50×50 + 50×7 + 5×50 + 5×7 = 2500 + 350 + 250 + 35 = 3135 \)
23. \( 59 \times 74 = ? \)
\( 59 × 74 = (60-1)×74 = 60×74 - 74 = 4440 - 74 = 4366 \)
24. \( 47 \times 55 = ? \)
\( 47 × 55 = (50-3)×55 = 50×55 - 3×55 = 2750 - 165 = 2585 \)

#### Row 5:
25. \( 49 \times 47 = ? \)
\( 49 × 47 = (50-1)(50-3) = 50×50 - 50×3 - 1×50 + 1×3 = 2500 - 150 - 50 + 3 = 2303 \)
26. \( 77 \times 88 = ? \)
\( 77 × 88 = (70+7)(80+8) = 70×80 + 70×8 + 7×80 + 7×8 = 5600 + 560 + 560 + 56 = 6776 \)
27. \( 85 \times 47 = ? \)
\( 85 × 47 = (80+5)×47 = 80×47 + 5×47 = 3760 + 235 = 3995 \)
28. \( 65 \times 37 = ? \)
\( 65 × 37 = (60+5)(30+7) = 60×30 + 60×7 + 5×30 + 5×7 = 1800 + 420 + 150 + 35 = 2405 \)
29. \( 44 \times 53 = ? \)
\( 44 × 53 = (40+4)(50+3) = 40×50 + 40×3 + 4×50 + 4×3 = 2000 + 120 + 200 + 12 = 2332 \)
30. \( 38 \times 99 = ? \)
\( 38 × 99 = 38 × (100 - 1) = 3800 - 38 = 3762 \)

#### Row 6:
31. \( 62 \times 74 = ? \)
\( 62 × 74 = (60+2)(70+4) = 60×70 + 60×4 + 2×70 + 2×4 = 4200 + 240 + 140 + 8 = 4588 \)
32. \( 73 \times 77 = ? \)
\( 73 × 77 = (70+3)(70+7) = 70×70 + 70×7 + 3×70 + 3×7 = 4900 + 490 + 210 + 21 = 5621 \)
33. \( 78 \times 40 = 3120 \)
34. \( 28 \times 44 = 1232 \)
35. \( 74 \times 12 = 888 \)
36. \( 78 \times 14 = ? \)
\( 78 × 14 = (70+8)(10+4) = 70×10 + 70×4 + 8×10 + 8×4 = 700 + 280 + 80 + 32 = 1092 \)
