Without delay, let's solve this. We've got 324 and we will be multiplying it by 18, that is, adding 324 to itself 18 times.
Step 1: 0 + 324 = 324
Step 2: 324 + 324 = 648
Step 3: 648 + 324 = 972
Step 4: 972 + 324 = 1296
Step 5: 1296 + 324 = 1620
Step 6: 1620 + 324 = 1944
Step 7: 1944 + 324 = 2268
Step 8: 2268 + 324 = 2592
Step 9: 2592 + 324 = 2916
Step 10: 2916 + 324 = 3240
Step 11: 3240 + 324 = 3564
Step 12: 3564 + 324 = 3888
Step 13: 3888 + 324 = 4212
Step 14: 4212 + 324 = 4536
Step 15: 4536 + 324 = 4860
Step 16: 4860 + 324 = 5184
Step 17: 5184 + 324 = 5508
Step 18: 5508 + 324 = 5832

So, 324*18 = 5832
