Let's get this math done. We have 147 and we're going to multiply it by 18. This is the same as taking 147 and adding it to itself 18 times.
Step 1: 0 + 147 = 147
Step 2: 147 + 147 = 294
Step 3: 294 + 147 = 441
Step 4: 441 + 147 = 588
Step 5: 588 + 147 = 735
Step 6: 735 + 147 = 882
Step 7: 882 + 147 = 1029
Step 8: 1029 + 147 = 1176
Step 9: 1176 + 147 = 1323
Step 10: 1323 + 147 = 1470
Step 11: 1470 + 147 = 1617
Step 12: 1617 + 147 = 1764
Step 13: 1764 + 147 = 1911
Step 14: 1911 + 147 = 2058
Step 15: 2058 + 147 = 2205
Step 16: 2205 + 147 = 2352
Step 17: 2352 + 147 = 2499
Step 18: 2499 + 147 = 2646

So, 147*18 = 2646
