Without delay, let's solve this. We've got 363 and we will be multiplying it by 18, that is, adding 363 to itself 18 times.
Step 1: 0 + 363 = 363
Step 2: 363 + 363 = 726
Step 3: 726 + 363 = 1089
Step 4: 1089 + 363 = 1452
Step 5: 1452 + 363 = 1815
Step 6: 1815 + 363 = 2178
Step 7: 2178 + 363 = 2541
Step 8: 2541 + 363 = 2904
Step 9: 2904 + 363 = 3267
Step 10: 3267 + 363 = 3630
Step 11: 3630 + 363 = 3993
Step 12: 3993 + 363 = 4356
Step 13: 4356 + 363 = 4719
Step 14: 4719 + 363 = 5082
Step 15: 5082 + 363 = 5445
Step 16: 5445 + 363 = 5808
Step 17: 5808 + 363 = 6171
Step 18: 6171 + 363 = 6534

So, 363*18 = 6534
