Sure thing, let's get straight to it. We start with 333 and we're going to multiply it by 12, which means adding 333 to itself 12 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

So, 333*12 = 3996
