Without delay, let's solve this. We've got 933 and we will be multiplying it by 9, that is, adding 933 to itself 9 times.
Step 1: 0 + 933 = 933
Step 2: 933 + 933 = 1866
Step 3: 1866 + 933 = 2799
Step 4: 2799 + 933 = 3732
Step 5: 3732 + 933 = 4665
Step 6: 4665 + 933 = 5598
Step 7: 5598 + 933 = 6531
Step 8: 6531 + 933 = 7464
Step 9: 7464 + 933 = 8397

So, 933*9 = 8397
