OK, let's crack this. We're given 497 and our task is to multiply it by 7. Essentially, we'll be adding 497 to itself 7 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

So, 497*7 = 3479
