Let's roll up our sleeves and solve this. We have 757 and we're going to multiply it by 11, essentially adding 757 to itself 11 times.
Step 1: 0 + 757 = 757
Step 2: 757 + 757 = 1514
Step 3: 1514 + 757 = 2271
Step 4: 2271 + 757 = 3028
Step 5: 3028 + 757 = 3785
Step 6: 3785 + 757 = 4542
Step 7: 4542 + 757 = 5299
Step 8: 5299 + 757 = 6056
Step 9: 6056 + 757 = 6813
Step 10: 6813 + 757 = 7570
Step 11: 7570 + 757 = 8327

So, 757*11 = 8327
