Let's get this math done. We have 867 and we're going to multiply it by 17. This is the same as taking 867 and adding it to itself 17 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
Step 12: 9537 + 867 = 10404
Step 13: 10404 + 867 = 11271
Step 14: 11271 + 867 = 12138
Step 15: 12138 + 867 = 13005
Step 16: 13005 + 867 = 13872
Step 17: 13872 + 867 = 14739

So, 867*17 = 14739
