OK, let's crack this. We're given 271 and our task is to multiply it by 42. Essentially, we'll be adding 271 to itself 42 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
Step 19: 4878 + 271 = 5149
Step 20: 5149 + 271 = 5420
Step 21: 5420 + 271 = 5691
Step 22: 5691 + 271 = 5962
Step 23: 5962 + 271 = 6233
Step 24: 6233 + 271 = 6504
Step 25: 6504 + 271 = 6775
Step 26: 6775 + 271 = 7046
Step 27: 7046 + 271 = 7317
Step 28: 7317 + 271 = 7588
Step 29: 7588 + 271 = 7859
Step 30: 7859 + 271 = 8130
Step 31: 8130 + 271 = 8401
Step 32: 8401 + 271 = 8672
Step 33: 8672 + 271 = 8943
Step 34: 8943 + 271 = 9214
Step 35: 9214 + 271 = 9485
Step 36: 9485 + 271 = 9756
Step 37: 9756 + 271 = 10027
Step 38: 10027 + 271 = 10298
Step 39: 10298 + 271 = 10569
Step 40: 10569 + 271 = 10840
Step 41: 10840 + 271 = 11111
Step 42: 11111 + 271 = 11382

So, 271*42 = 11382
