Sure thing, let's get straight to it. We start with 406 and we're going to multiply it by 33, which means adding 406 to itself 33 times.
Step 1: 0 + 406 = 406
Step 2: 406 + 406 = 812
Step 3: 812 + 406 = 1218
Step 4: 1218 + 406 = 1624
Step 5: 1624 + 406 = 2030
Step 6: 2030 + 406 = 2436
Step 7: 2436 + 406 = 2842
Step 8: 2842 + 406 = 3248
Step 9: 3248 + 406 = 3654
Step 10: 3654 + 406 = 4060
Step 11: 4060 + 406 = 4466
Step 12: 4466 + 406 = 4872
Step 13: 4872 + 406 = 5278
Step 14: 5278 + 406 = 5684
Step 15: 5684 + 406 = 6090
Step 16: 6090 + 406 = 6496
Step 17: 6496 + 406 = 6902
Step 18: 6902 + 406 = 7308
Step 19: 7308 + 406 = 7714
Step 20: 7714 + 406 = 8120
Step 21: 8120 + 406 = 8526
Step 22: 8526 + 406 = 8932
Step 23: 8932 + 406 = 9338
Step 24: 9338 + 406 = 9744
Step 25: 9744 + 406 = 10150
Step 26: 10150 + 406 = 10556
Step 27: 10556 + 406 = 10962
Step 28: 10962 + 406 = 11368
Step 29: 11368 + 406 = 11774
Step 30: 11774 + 406 = 12180
Step 31: 12180 + 406 = 12586
Step 32: 12586 + 406 = 12992
Step 33: 12992 + 406 = 13398

So, 406*33 = 13398
