Let's get this math done. We have 872 and we're going to multiply it by 11. This is the same as taking 872 and adding it to itself 11 times.
Step 1: 0 + 872 = 872
Step 2: 872 + 872 = 1744
Step 3: 1744 + 872 = 2616
Step 4: 2616 + 872 = 3488
Step 5: 3488 + 872 = 4360
Step 6: 4360 + 872 = 5232
Step 7: 5232 + 872 = 6104
Step 8: 6104 + 872 = 6976
Step 9: 6976 + 872 = 7848
Step 10: 7848 + 872 = 8720
Step 11: 8720 + 872 = 9592

So, 872*11 = 9592
