Step 6: 4540 + 908 = 5448
Step 7: 5448 + 908 = 6356
Step 8: 6356 + 908 = 7264
Step 9: 7264 + 908 = 8172
Step 10: 8172 + 908 = 9080
Step 11: 9080 + 908 = 9988
Step 12: 9988 + 908 = 10896
Step 13: 10896 + 908 = 11804
Step 14: 11804 + 908 = 12712
Step 15: 12712 + 908 = 13620
Step 16: 13620 + 908 = 14528
Step 17: 14528 + 908 = 15436
Step 18: 15436 + 908 = 16344
Step 19: 16344 + 908 = 17252
Step 20: 17252 + 908 = 18160
Step 21: 18160 + 908 = 19068
Step 22: 19068 + 908 = 19976
Step 23: 19976 + 908 = 20884
Step 24: 20884 + 908 = 21792
Step 25: 21792 + 908 = 22700
Step 26: 22700 + 908 = 23608
Step 27: 23608 + 908 = 24516
Step 28: 24516 + 908 = 25424
Step 29: 25424 + 908 = 26332
Step 30: 26332 + 908 = 27240
Step 31: 27240 + 908 = 28148
Step 32: 28148 + 908 = 29056
Step 33: 29056 + 908 = 29964
Step 34: 29964 + 908 = 30872
Step 35: 30872 + 908 = 31780
Step 36: 31780 + 908 = 32688
Step 37: 32688 + 908 = 33596
Step 38: 33596 + 908 = 34504
Step 39: 34504 + 908 = 35412
Step 40: 35412 + 908 = 36320
Step 41: 36320 + 908 = 37228
Step 42: 37228 + 908 = 38136

So, 908*42 = 38136
