Let's get this math done. We have 634 and we're going to multiply it by 17. This is the same as taking 634 and adding it to itself 17 times.
Step 1: 0 + 634 = 634
Step 2: 634 + 634 = 1268
Step 3: 1268 + 634 = 1902
Step 4: 1902 + 634 = 2536
Step 5: 2536 + 634 = 3170
Step 6: 3170 + 634 = 3804
Step 7: 3804 + 634 = 4438
Step 8: 4438 + 634 = 5072
Step 9: 5072 + 634 = 5706
Step 10: 5706 + 634 = 6340
Step 11: 6340 + 634 = 6974
Step 12: 6974 + 634 = 7608
Step 13: 7608 + 634 = 8242
Step 14: 8242 + 634 = 8876
Step 15: 8876 + 634 = 9510
Step 16: 9510 + 634 = 10144
Step 17: 10144 + 634 = 10778

So, 634*17 = 10778
