4. $11 \times 4 = 44$
5. $4 \times 4 = 16$
6. $7 \times 4 = 28$
7. $6 \times 4 = 24$
8. $10 \times 4 = 40$
9. $3 \times 4 = 12$
10. $2 \times 4 = 8$
Row 2:
11. $12 \times 4 = 48$
12. $8 \times 4 = 32$
13. $4 \times 5 = 20$ (Note: The multiplier here is 5, not 4)
14. $4 \times 11 = 44$
15. $4 \times 2 = 8$
16. $4 \times 9 = 36$
17. $4 \times 7 = 28$
18. $4 \times 4 = 16$
19. $4 \times 10 = 40$
20. $4 \times 1 = 4$
Row 3:
21. $4 \times 8 = 32$
22. $4 \times 12 = 48$
23. $4 \times 6 = 24$
24. $4 \times 3 = 12$
25. $11 \times 4 = 44$
26. $3 \times 4 = 12$
27. $4 \times 8 = 32$
28. $2 \times 4 = 8$
29. $1 \times 4 = 4$
30. $4 \times 6 = 24$
Row 4:
31. $4 \times 10 = 40$
32. $7 \times 4 = 28$
33. $4 \times 5 = 20$ (Note: The multiplier here is 5, not 4)
34. $4 \times 4 = 16$
35. $4 \times 9 = 36$
36. $12 \times 4 = 48$
37. $2 \times 4 = 8$
38. $4 \times 4 = 16$
39. $11 \times 4 = 44$
40. $4 \times 5 = 20$ (Note: The multiplier here is 5, not 4)
Row 5:
41. $4 \times 7 = 28$
42. $1 \times 4 = 4$
43. $4 \times 10 = 40$
44. $4 \times 6 = 24$
45. $12 \times 4 = 48$
46. $3 \times 4 = 12$
47. $4 \times 9 = 36$
48. $4 \times 8 = 32$
49. $8 \times 4 = 32$
50. $4 \times 7 = 28$
