OK, let's crack this. We're given 691 and our task is to multiply it by 17. Essentially, we'll be adding 691 to itself 17 times.
Step 1: 0 + 691 = 691
Step 2: 691 + 691 = 1382
Step 3: 1382 + 691 = 2073
Step 4: 2073 + 691 = 2764
Step 5: 2764 + 691 = 3455
Step 6: 3455 + 691 = 4146
Step 7: 4146 + 691 = 4837
Step 8: 4837 + 691 = 5528
Step 9: 5528 + 691 = 6219
Step 10: 6219 + 691 = 6910
Step 11: 6910 + 691 = 7601
Step 12: 7601 + 691 = 8292
Step 13: 8292 + 691 = 8983
Step 14: 8983 + 691 = 9674
Step 15: 9674 + 691 = 10365
Step 16: 10365 + 691 = 11056
Step 17: 11056 + 691 = 11747

So, 691*17 = 11747
