OK, let's work through this together. We're starting with 271 and we're going to multiply it by 12, which means we add 271 to itself 12 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

So, 271*12 = 3252
