Let's get this math done. We have 285 and we're going to multiply it by 6. This is the same as taking 285 and adding it to itself 6 times.
Step 1: 0 + 285 = 285
Step 2: 285 + 285 = 570
Step 3: 570 + 285 = 855
Step 4: 855 + 285 = 1140
Step 5: 1140 + 285 = 1425
Step 6: 1425 + 285 = 1710

So, 285*6 = 1710
