Step 1: 0 + 398 = 398
Step 2: 398 + 398 = 796
Step 3: 796 + 398 = 1194
Step 4: 1194 + 398 = 1592
Step 5: 1592 + 398 = 1990
Step 6: 1990 + 398 = 2388
Step 7: 2388 + 398 = 2786
Step 8: 2786 + 398 = 3184
Step 9: 3184 + 398 = 3582
Step 10: 3582 + 398 = 3980
Step 11: 3980 + 398 = 4378
Step 12: 4378 + 398 = 4776
Step 13: 4776 + 398 = 5174
Step 14: 5174 + 398 = 5572
Step 15: 5572 + 398 = 5970
Step 16: 5970 + 398 = 6368
Step 17: 6368 + 398 = 6766
Step 18: 6766 + 398 = 7164
Step 19: 7164 + 398 = 7562
Step 20: 7562 + 398 = 7960
Step 21: 7960 + 398 = 8358
Step 22: 8358 + 398 = 8756
Step 23: 8756 + 398 = 9154
Step 24: 9154 + 398 = 9552
Step 25: 9552 + 398 = 9950
Step 26: 9950 + 398 = 10348
Step 27: 10348 + 398 = 10746
Step 28: 10746 + 398 = 11144
Step 29: 11144 + 398 = 11542
Step 30: 11542 + 398 = 11940
Step 31: 11940 + 398 = 12338
Step 32: 12338 + 398 = 12736
Step 33: 12736 + 398 = 13134
Step 34: 13134 + 398 = 13532
Step 35: 13532 + 398 = 13930
Step 36: 13930 + 398 = 14328
Step 37: 14328 + 398 = 14726

So, 398*37 = 14726
