OK, let's crack this. We're given 347 and our task is to multiply it by 38. Essentially, we'll be adding 347 to itself 38 times.
Step 1: 0 + 347 = 347
Step 2: 347 + 347 = 694
Step 3: 694 + 347 = 1041
Step 4: 1041 + 347 = 1388
Step 5: 1388 + 347 = 1735
Step 6: 1735 + 347 = 2082
Step 7: 2082 + 347 = 2429
Step 8: 2429 + 347 = 2776
Step 9: 2776 + 347 = 3123
Step 10: 3123 + 347 = 3470
Step 11: 3470 + 347 = 3817
Step 12: 3817 + 347 = 4164
Step 13: 4164 + 347 = 4511
Step 14: 4511 + 347 = 4858
Step 15: 4858 + 347 = 5205
Step 16: 5205 + 347 = 5552
Step 17: 5552 + 347 = 5899
Step 18: 5899 + 347 = 6246
Step 19: 6246 + 347 = 6593
Step 20: 6593 + 347 = 6940
Step 21: 6940 + 347 = 7287
Step 22: 7287 + 347 = 7634
Step 23: 7634 + 347 = 7981
Step 24: 7981 + 347 = 8328
Step 25: 8328 + 347 = 8675
Step 26: 8675 + 347 = 9022
Step 27: 9022 + 347 = 9369
Step 28: 9369 + 347 = 9716
Step 29: 9716 + 347 = 10063
Step 30: 10063 + 347 = 10410
Step 31: 10410 + 347 = 10757
Step 32: 10757 + 347 = 11104
Step 33: 11104 + 347 = 11451
Step 34: 11451 + 347 = 11798
Step 35: 11798 + 347 = 12145
Step 36: 12145 + 347 = 12492
Step 37: 12492 + 347 = 12839
Step 38: 12839 + 347 = 13186

So, 347*38 = 13186
