OK, let's work through this together. We're starting with 528 and we're going to multiply it by 16, which means we add 528 to itself 16 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
Step 8: 3696 + 528 = 4224
Step 9: 4224 + 528 = 4752
Step 10: 4752 + 528 = 5280
Step 11: 5280 + 528 = 5808
Step 12: 5808 + 528 = 6336
Step 13: 6336 + 528 = 6864
Step 14: 6864 + 528 = 7392
Step 15: 7392 + 528 = 7920
Step 16: 7920 + 528 = 8448

So, 528*16 = 8448
