Without delay, let's solve this. We've got 198 and we will be multiplying it by 9, that is, adding 198 to itself 9 times.
Step 1: 0 + 198 = 198
Step 2: 198 + 198 = 396
Step 3: 396 + 198 = 594
Step 4: 594 + 198 = 792
Step 5: 792 + 198 = 990
Step 6: 990 + 198 = 1188
Step 7: 1188 + 198 = 1386
Step 8: 1386 + 198 = 1584
Step 9: 1584 + 198 = 1782

So, 198*9 = 1782
