Let's get this math done. We have 576 and we're going to multiply it by 6. This is the same as taking 576 and adding it to itself 6 times.
Step 1: 0 + 576 = 576
Step 2: 576 + 576 = 1152
Step 3: 1152 + 576 = 1728
Step 4: 1728 + 576 = 2304
Step 5: 2304 + 576 = 2880
Step 6: 2880 + 576 = 3456

So, 576*6 = 3456
