Alright, let's solve this math problem step by step. First, we have the number 647. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 16. So, we're going to take the number 647 and add it to itself 16 times.
Step 1: 0 + 647 = 647
Step 2: 647 + 647 = 1294
Step 3: 1294 + 647 = 1941
Step 4: 1941 + 647 = 2588
Step 5: 2588 + 647 = 3235
Step 6: 3235 + 647 = 3882
Step 7: 3882 + 647 = 4529
Step 8: 4529 + 647 = 5176
Step 9: 5176 + 647 = 5823
Step 10: 5823 + 647 = 6470
Step 11: 6470 + 647 = 7117
Step 12: 7117 + 647 = 7764
Step 13: 7764 + 647 = 8411
Step 14: 8411 + 647 = 9058
Step 15: 9058 + 647 = 9705
Step 16: 9705 + 647 = 10352

So, 647*16 = 10352
