OK, let's work through this together. We're starting with 221 and we're going to multiply it by 12, which means we add 221 to itself 12 times.
Step 1: 0 + 221 = 221
Step 2: 221 + 221 = 442
Step 3: 442 + 221 = 663
Step 4: 663 + 221 = 884
Step 5: 884 + 221 = 1105
Step 6: 1105 + 221 = 1326
Step 7: 1326 + 221 = 1547
Step 8: 1547 + 221 = 1768
Step 9: 1768 + 221 = 1989
Step 10: 1989 + 221 = 2210
Step 11: 2210 + 221 = 2431
Step 12: 2431 + 221 = 2652

So, 221*12 = 2652
