OK, let's work through this together. We're starting with 494 and we're going to multiply it by 16, which means we add 494 to itself 16 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
Step 11: 4940 + 494 = 5434
Step 12: 5434 + 494 = 5928
Step 13: 5928 + 494 = 6422
Step 14: 6422 + 494 = 6916
Step 15: 6916 + 494 = 7410
Step 16: 7410 + 494 = 7904

So, 494*16 = 7904
