Step 4: 2022 + 674 = 2696
Step 5: 2696 + 674 = 3370
Step 6: 3370 + 674 = 4044
Step 7: 4044 + 674 = 4718
Step 8: 4718 + 674 = 5392
Step 9: 5392 + 674 = 6066
Step 10: 6066 + 674 = 6740
Step 11: 6740 + 674 = 7414
Step 12: 7414 + 674 = 8088
Step 13: 8088 + 674 = 8762
Step 14: 8762 + 674 = 9436
Step 15: 9436 + 674 = 10110
Step 16: 10110 + 674 = 10784
Step 17: 10784 + 674 = 11458
Step 18: 11458 + 674 = 12132
Step 19: 12132 + 674 = 12806
Step 20: 12806 + 674 = 13480
Step 21: 13480 + 674 = 14154
Step 22: 14154 + 674 = 14828
Step 23: 14828 + 674 = 15502
Step 24: 15502 + 674 = 16176
Step 25: 16176 + 674 = 16850
Step 26: 16850 + 674 = 17524
Step 27: 17524 + 674 = 18198
Step 28: 18198 + 674 = 18872
Step 29: 18872 + 674 = 19546
Step 30: 19546 + 674 = 20220
Step 31: 20220 + 674 = 20894
Step 32: 20894 + 674 = 21568
Step 33: 21568 + 674 = 22242
Step 34: 22242 + 674 = 22916
Step 35: 22916 + 674 = 23590
Step 36: 23590 + 674 = 24264
Step 37: 24264 + 674 = 24938
Step 38: 24938 + 674 = 25612

So, 674*38 = 25612
