Sure thing! We've got 691 and we're gonna multiply it by 8. That's the same as adding 691 to itself 8 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

So, 691*8 = 5528
