OK, let's crack this. We're given 497 and our task is to multiply it by 28. Essentially, we'll be adding 497 to itself 28 times.
Step 1: 0 + 497 = 497
Step 2: 497 + 497 = 994
Step 3: 994 + 497 = 1491
Step 4: 1491 + 497 = 1988
Step 5: 1988 + 497 = 2485
Step 6: 2485 + 497 = 2982
Step 7: 2982 + 497 = 3479
Step 8: 3479 + 497 = 3976
Step 9: 3976 + 497 = 4473
Step 10: 4473 + 497 = 4970
Step 11: 4970 + 497 = 5467
Step 12: 5467 + 497 = 5964
Step 13: 5964 + 497 = 6461
Step 14: 6461 + 497 = 6958
Step 15: 6958 + 497 = 7455
Step 16: 7455 + 497 = 7952
Step 17: 7952 + 497 = 8449
Step 18: 8449 + 497 = 8946
Step 19: 8946 + 497 = 9443
Step 20: 9443 + 497 = 9940
Step 21: 9940 + 497 = 10437
Step 22: 10437 + 497 = 10934
Step 23: 10934 + 497 = 11431
Step 24: 11431 + 497 = 11928
Step 25: 11928 + 497 = 12425
Step 26: 12425 + 497 = 12922
Step 27: 12922 + 497 = 13419
Step 28: 13419 + 497 = 13916

So, 497*28 = 13916
