OK, let's crack this. We're given 508 and our task is to multiply it by 9. Essentially, we'll be adding 508 to itself 9 times.
Step 1: 0 + 508 = 508
Step 2: 508 + 508 = 1016
Step 3: 1016 + 508 = 1524
Step 4: 1524 + 508 = 2032
Step 5: 2032 + 508 = 2540
Step 6: 2540 + 508 = 3048
Step 7: 3048 + 508 = 3556
Step 8: 3556 + 508 = 4064
Step 9: 4064 + 508 = 4572

So, 508*9 = 4572
