Without delay, let's solve this. We've got 528 and we will be multiplying it by 7, that is, adding 528 to itself 7 times.
Step 1: 0 + 528 = 528
Step 2: 528 + 528 = 1056
Step 3: 1056 + 528 = 1584
Step 4: 1584 + 528 = 2112
Step 5: 2112 + 528 = 2640
Step 6: 2640 + 528 = 3168
Step 7: 3168 + 528 = 3696

So, 528*7 = 3696
