Without delay, let's solve this. We've got 483 and we will be multiplying it by 39, that is, adding 483 to itself 39 times.
Step 1: 0 + 483 = 483
Step 2: 483 + 483 = 966
Step 3: 966 + 483 = 1449
Step 4: 1449 + 483 = 1932
Step 5: 1932 + 483 = 2415
Step 6: 2415 + 483 = 2898
Step 7: 2898 + 483 = 3381
Step 8: 3381 + 483 = 3864
Step 9: 3864 + 483 = 4347
Step 10: 4347 + 483 = 4830
Step 11: 4830 + 483 = 5313
Step 12: 5313 + 483 = 5796
Step 13: 5796 + 483 = 6279
Step 14: 6279 + 483 = 6762
Step 15: 6762 + 483 = 7245
Step 16: 7245 + 483 = 7728
Step 17: 7728 + 483 = 8211
Step 18: 8211 + 483 = 8694
Step 19: 8694 + 483 = 9177
Step 20: 9177 + 483 = 9660
Step 21: 9660 + 483 = 10143
Step 22: 10143 + 483 = 10626
Step 23: 10626 + 483 = 11109
Step 24: 11109 + 483 = 11592
Step 25: 11592 + 483 = 12075
Step 26: 12075 + 483 = 12558
Step 27: 12558 + 483 = 13041
Step 28: 13041 + 483 = 13524
Step 29: 13524 + 483 = 14007
Step 30: 14007 + 483 = 14490
Step 31: 14490 + 483 = 14973
Step 32: 14973 + 483 = 15456
Step 33: 15456 + 483 = 15939
Step 34: 15939 + 483 = 16422
Step 35: 16422 + 483 = 16905
Step 36: 16905 + 483 = 17388
Step 37: 17388 + 483 = 17871
Step 38: 17871 + 483 = 18354
Step 39: 18354 + 483 = 18837

So, 483*39 = 18837
