Let's get this math done. We have 0 and we're going to multiply it by 11. This is the same as taking 0 and adding it to itself 11 times.
Step 1: 0 + 0 = 0
Step 2: 0 + 0 = 0
Step 3: 0 + 0 = 0
Step 4: 0 + 0 = 0
Step 5: 0 + 0 = 0
Step 6: 0 + 0 = 0
Step 7: 0 + 0 = 0
Step 8: 0 + 0 = 0
Step 9: 0 + 0 = 0
Step 10: 0 + 0 = 0
Step 11: 0 + 0 = 0

So, 0*11 = 0
