Let's get this math done. We have 607 and we're going to multiply it by 17. This is the same as taking 607 and adding it to itself 17 times.
Step 1: 0 + 607 = 607
Step 2: 607 + 607 = 1214
Step 3: 1214 + 607 = 1821
Step 4: 1821 + 607 = 2428
Step 5: 2428 + 607 = 3035
Step 6: 3035 + 607 = 3642
Step 7: 3642 + 607 = 4249
Step 8: 4249 + 607 = 4856
Step 9: 4856 + 607 = 5463
Step 10: 5463 + 607 = 6070
Step 11: 6070 + 607 = 6677
Step 12: 6677 + 607 = 7284
Step 13: 7284 + 607 = 7891
Step 14: 7891 + 607 = 8498
Step 15: 8498 + 607 = 9105
Step 16: 9105 + 607 = 9712
Step 17: 9712 + 607 = 10319

So, 607*17 = 10319
