Without delay, let's solve this. We've got 793 and we will be multiplying it by 11, that is, adding 793 to itself 11 times.
Step 1: 0 + 793 = 793
Step 2: 793 + 793 = 1586
Step 3: 1586 + 793 = 2379
Step 4: 2379 + 793 = 3172
Step 5: 3172 + 793 = 3965
Step 6: 3965 + 793 = 4758
Step 7: 4758 + 793 = 5551
Step 8: 5551 + 793 = 6344
Step 9: 6344 + 793 = 7137
Step 10: 7137 + 793 = 7930
Step 11: 7930 + 793 = 8723

So, 793*11 = 8723
