Step 13: 5016 + 418 = 5434
Step 14: 5434 + 418 = 5852
Step 15: 5852 + 418 = 6270
Step 16: 6270 + 418 = 6688
Step 17: 6688 + 418 = 7106
Step 18: 7106 + 418 = 7524
Step 19: 7524 + 418 = 7942
Step 20: 7942 + 418 = 8360
Step 21: 8360 + 418 = 8778
Step 22: 8778 + 418 = 9196
Step 23: 9196 + 418 = 9614
Step 24: 9614 + 418 = 10032
Step 25: 10032 + 418 = 10450
Step 26: 10450 + 418 = 10868
Step 27: 10868 + 418 = 11286
Step 28: 11286 + 418 = 11704
Step 29: 11704 + 418 = 12122
Step 30: 12122 + 418 = 12540
Step 31: 12540 + 418 = 12958
Step 32: 12958 + 418 = 13376
Step 33: 13376 + 418 = 13794
Step 34: 13794 + 418 = 14212
Step 35: 14212 + 418 = 14630
Step 36: 14630 + 418 = 15048
Step 37: 15048 + 418 = 15466
Step 38: 15466 + 418 = 15884
Step 39: 15884 + 418 = 16302
Step 40: 16302 + 418 = 16720
Step 41: 16720 + 418 = 17138
Step 42: 17138 + 418 = 17556

So, 418*42 = 17556
