Let's get this math done. We have 172 and we're going to multiply it by 6. This is the same as taking 172 and adding it to itself 6 times.
Step 1: 0 + 172 = 172
Step 2: 172 + 172 = 344
Step 3: 344 + 172 = 516
Step 4: 516 + 172 = 688
Step 5: 688 + 172 = 860
Step 6: 860 + 172 = 1032

So, 172*6 = 1032
