OK, let's crack this. We're given 494 and our task is to multiply it by 10. Essentially, we'll be adding 494 to itself 10 times.
Step 1: 0 + 494 = 494
Step 2: 494 + 494 = 988
Step 3: 988 + 494 = 1482
Step 4: 1482 + 494 = 1976
Step 5: 1976 + 494 = 2470
Step 6: 2470 + 494 = 2964
Step 7: 2964 + 494 = 3458
Step 8: 3458 + 494 = 3952
Step 9: 3952 + 494 = 4446
Step 10: 4446 + 494 = 4940

So, 494*10 = 4940
