Sure thing, let's get straight to it. We start with 538 and we're going to multiply it by 39, which means adding 538 to itself 39 times.
Step 1: 0 + 538 = 538
Step 2: 538 + 538 = 1076
Step 3: 1076 + 538 = 1614
Step 4: 1614 + 538 = 2152
Step 5: 2152 + 538 = 2690
Step 6: 2690 + 538 = 3228
Step 7: 3228 + 538 = 3766
Step 8: 3766 + 538 = 4304
Step 9: 4304 + 538 = 4842
Step 10: 4842 + 538 = 5380
Step 11: 5380 + 538 = 5918
Step 12: 5918 + 538 = 6456
Step 13: 6456 + 538 = 6994
Step 14: 6994 + 538 = 7532
Step 15: 7532 + 538 = 8070
Step 16: 8070 + 538 = 8608
Step 17: 8608 + 538 = 9146
Step 18: 9146 + 538 = 9684
Step 19: 9684 + 538 = 10222
Step 20: 10222 + 538 = 10760
Step 21: 10760 + 538 = 11298
Step 22: 11298 + 538 = 11836
Step 23: 11836 + 538 = 12374
Step 24: 12374 + 538 = 12912
Step 25: 12912 + 538 = 13450
Step 26: 13450 + 538 = 13988
Step 27: 13988 + 538 = 14526
Step 28: 14526 + 538 = 15064
Step 29: 15064 + 538 = 15602
Step 30: 15602 + 538 = 16140
Step 31: 16140 + 538 = 16678
Step 32: 16678 + 538 = 17216
Step 33: 17216 + 538 = 17754
Step 34: 17754 + 538 = 18292
Step 35: 18292 + 538 = 18830
Step 36: 18830 + 538 = 19368
Step 37: 19368 + 538 = 19906
Step 38: 19906 + 538 = 20444
Step 39: 20444 + 538 = 20982

So, 538*39 = 20982
