Sure thing, let's get straight to it. We start with 867 and we're going to multiply it by 7, which means adding 867 to itself 7 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

So, 867*7 = 6069
