Alright, let's solve this math problem step by step. First, we have the number 867. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 11. So, we're going to take the number 867 and add it to itself 11 times.
Step 1: 0 + 867 = 867
Step 2: 867 + 867 = 1734
Step 3: 1734 + 867 = 2601
Step 4: 2601 + 867 = 3468
Step 5: 3468 + 867 = 4335
Step 6: 4335 + 867 = 5202
Step 7: 5202 + 867 = 6069
Step 8: 6069 + 867 = 6936
Step 9: 6936 + 867 = 7803
Step 10: 7803 + 867 = 8670
Step 11: 8670 + 867 = 9537

So, 867*11 = 9537
