OK, let's work through this together. We're starting with 547 and we're going to multiply it by 9, which means we add 547 to itself 9 times.
Step 1: 0 + 547 = 547
Step 2: 547 + 547 = 1094
Step 3: 1094 + 547 = 1641
Step 4: 1641 + 547 = 2188
Step 5: 2188 + 547 = 2735
Step 6: 2735 + 547 = 3282
Step 7: 3282 + 547 = 3829
Step 8: 3829 + 547 = 4376
Step 9: 4376 + 547 = 4923

So, 547*9 = 4923
