Without delay, let's solve this. We've got 571 and we will be multiplying it by 9, that is, adding 571 to itself 9 times.
Step 1: 0 + 571 = 571
Step 2: 571 + 571 = 1142
Step 3: 1142 + 571 = 1713
Step 4: 1713 + 571 = 2284
Step 5: 2284 + 571 = 2855
Step 6: 2855 + 571 = 3426
Step 7: 3426 + 571 = 3997
Step 8: 3997 + 571 = 4568
Step 9: 4568 + 571 = 5139

So, 571*9 = 5139
