Without delay, let's solve this. We've got 522 and we will be multiplying it by 12, that is, adding 522 to itself 12 times.
Step 1: 0 + 522 = 522
Step 2: 522 + 522 = 1044
Step 3: 1044 + 522 = 1566
Step 4: 1566 + 522 = 2088
Step 5: 2088 + 522 = 2610
Step 6: 2610 + 522 = 3132
Step 7: 3132 + 522 = 3654
Step 8: 3654 + 522 = 4176
Step 9: 4176 + 522 = 4698
Step 10: 4698 + 522 = 5220
Step 11: 5220 + 522 = 5742
Step 12: 5742 + 522 = 6264

So, 522*12 = 6264
