Alright, let's solve this math problem step by step. First, we have the number 333. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 11. So, we're going to take the number 333 and add it to itself 11 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

So, 333*11 = 3663
