Step 1: 0 + 297 = 297
Step 2: 297 + 297 = 594
Step 3: 594 + 297 = 891
Step 4: 891 + 297 = 1188
Step 5: 1188 + 297 = 1485
Step 6: 1485 + 297 = 1782
Step 7: 1782 + 297 = 2079
Step 8: 2079 + 297 = 2376
Step 9: 2376 + 297 = 2673
Step 10: 2673 + 297 = 2970
Step 11: 2970 + 297 = 3267
Step 12: 3267 + 297 = 3564
Step 13: 3564 + 297 = 3861
Step 14: 3861 + 297 = 4158
Step 15: 4158 + 297 = 4455
Step 16: 4455 + 297 = 4752
Step 17: 4752 + 297 = 5049
Step 18: 5049 + 297 = 5346
Step 19: 5346 + 297 = 5643
Step 20: 5643 + 297 = 5940
Step 21: 5940 + 297 = 6237
Step 22: 6237 + 297 = 6534
Step 23: 6534 + 297 = 6831
Step 24: 6831 + 297 = 7128
Step 25: 7128 + 297 = 7425
Step 26: 7425 + 297 = 7722
Step 27: 7722 + 297 = 8019
Step 28: 8019 + 297 = 8316
Step 29: 8316 + 297 = 8613
Step 30: 8613 + 297 = 8910
Step 31: 8910 + 297 = 9207
Step 32: 9207 + 297 = 9504
Step 33: 9504 + 297 = 9801
Step 34: 9801 + 297 = 10098
Step 35: 10098 + 297 = 10395
Step 36: 10395 + 297 = 10692
Step 37: 10692 + 297 = 10989
Step 38: 10989 + 297 = 11286
Step 39: 11286 + 297 = 11583
Step 40: 11583 + 297 = 11880
Step 41: 11880 + 297 = 12177
Step 42: 12177 + 297 = 12474

So, 297*42 = 12474
