OK, let's crack this. We're given 271 and our task is to multiply it by 18. Essentially, we'll be adding 271 to itself 18 times.
Step 1: 0 + 271 = 271
Step 2: 271 + 271 = 542
Step 3: 542 + 271 = 813
Step 4: 813 + 271 = 1084
Step 5: 1084 + 271 = 1355
Step 6: 1355 + 271 = 1626
Step 7: 1626 + 271 = 1897
Step 8: 1897 + 271 = 2168
Step 9: 2168 + 271 = 2439
Step 10: 2439 + 271 = 2710
Step 11: 2710 + 271 = 2981
Step 12: 2981 + 271 = 3252
Step 13: 3252 + 271 = 3523
Step 14: 3523 + 271 = 3794
Step 15: 3794 + 271 = 4065
Step 16: 4065 + 271 = 4336
Step 17: 4336 + 271 = 4607
Step 18: 4607 + 271 = 4878

So, 271*18 = 4878
