Let's roll up our sleeves and solve this. We have 726 and we're going to multiply it by 11, essentially adding 726 to itself 11 times.
Step 1: 0 + 726 = 726
Step 2: 726 + 726 = 1452
Step 3: 1452 + 726 = 2178
Step 4: 2178 + 726 = 2904
Step 5: 2904 + 726 = 3630
Step 6: 3630 + 726 = 4356
Step 7: 4356 + 726 = 5082
Step 8: 5082 + 726 = 5808
Step 9: 5808 + 726 = 6534
Step 10: 6534 + 726 = 7260
Step 11: 7260 + 726 = 7986

So, 726*11 = 7986
