Without delay, let's solve this. We've got 539 and we will be multiplying it by 27, that is, adding 539 to itself 27 times.
Step 1: 0 + 539 = 539
Step 2: 539 + 539 = 1078
Step 3: 1078 + 539 = 1617
Step 4: 1617 + 539 = 2156
Step 5: 2156 + 539 = 2695
Step 6: 2695 + 539 = 3234
Step 7: 3234 + 539 = 3773
Step 8: 3773 + 539 = 4312
Step 9: 4312 + 539 = 4851
Step 10: 4851 + 539 = 5390
Step 11: 5390 + 539 = 5929
Step 12: 5929 + 539 = 6468
Step 13: 6468 + 539 = 7007
Step 14: 7007 + 539 = 7546
Step 15: 7546 + 539 = 8085
Step 16: 8085 + 539 = 8624
Step 17: 8624 + 539 = 9163
Step 18: 9163 + 539 = 9702
Step 19: 9702 + 539 = 10241
Step 20: 10241 + 539 = 10780
Step 21: 10780 + 539 = 11319
Step 22: 11319 + 539 = 11858
Step 23: 11858 + 539 = 12397
Step 24: 12397 + 539 = 12936
Step 25: 12936 + 539 = 13475
Step 26: 13475 + 539 = 14014
Step 27: 14014 + 539 = 14553

So, 539*27 = 14553
