Without delay, let's solve this. We've got 911 and we will be multiplying it by 11, that is, adding 911 to itself 11 times.
Step 1: 0 + 911 = 911
Step 2: 911 + 911 = 1822
Step 3: 1822 + 911 = 2733
Step 4: 2733 + 911 = 3644
Step 5: 3644 + 911 = 4555
Step 6: 4555 + 911 = 5466
Step 7: 5466 + 911 = 6377
Step 8: 6377 + 911 = 7288
Step 9: 7288 + 911 = 8199
Step 10: 8199 + 911 = 9110
Step 11: 9110 + 911 = 10021

So, 911*11 = 10021
