Without delay, let's solve this. We've got 522 and we will be multiplying it by 7, that is, adding 522 to itself 7 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

So, 522*7 = 3654
