Without delay, let's solve this. We've got 324 and we will be multiplying it by 38, that is, adding 324 to itself 38 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
Step 19: 5832 + 324 = 6156
Step 20: 6156 + 324 = 6480
Step 21: 6480 + 324 = 6804
Step 22: 6804 + 324 = 7128
Step 23: 7128 + 324 = 7452
Step 24: 7452 + 324 = 7776
Step 25: 7776 + 324 = 8100
Step 26: 8100 + 324 = 8424
Step 27: 8424 + 324 = 8748
Step 28: 8748 + 324 = 9072
Step 29: 9072 + 324 = 9396
Step 30: 9396 + 324 = 9720
Step 31: 9720 + 324 = 10044
Step 32: 10044 + 324 = 10368
Step 33: 10368 + 324 = 10692
Step 34: 10692 + 324 = 11016
Step 35: 11016 + 324 = 11340
Step 36: 11340 + 324 = 11664
Step 37: 11664 + 324 = 11988
Step 38: 11988 + 324 = 12312

So, 324*38 = 12312
