Let's get this math done. We have 401 and we're going to multiply it by 6. This is the same as taking 401 and adding it to itself 6 times.
Step 1: 0 + 401 = 401
Step 2: 401 + 401 = 802
Step 3: 802 + 401 = 1203
Step 4: 1203 + 401 = 1604
Step 5: 1604 + 401 = 2005
Step 6: 2005 + 401 = 2406

So, 401*6 = 2406
