Let's get this math done. We have 333 and we're going to multiply it by 16. This is the same as taking 333 and adding it to itself 16 times.
Step 1: 0 + 333 = 333
Step 2: 333 + 333 = 666
Step 3: 666 + 333 = 999
Step 4: 999 + 333 = 1332
Step 5: 1332 + 333 = 1665
Step 6: 1665 + 333 = 1998
Step 7: 1998 + 333 = 2331
Step 8: 2331 + 333 = 2664
Step 9: 2664 + 333 = 2997
Step 10: 2997 + 333 = 3330
Step 11: 3330 + 333 = 3663
Step 12: 3663 + 333 = 3996
Step 13: 3996 + 333 = 4329
Step 14: 4329 + 333 = 4662
Step 15: 4662 + 333 = 4995
Step 16: 4995 + 333 = 5328

So, 333*16 = 5328
