Sure thing, let's get straight to it. We start with 609 and we're going to multiply it by 12, which means adding 609 to itself 12 times.
Step 1: 0 + 609 = 609
Step 2: 609 + 609 = 1218
Step 3: 1218 + 609 = 1827
Step 4: 1827 + 609 = 2436
Step 5: 2436 + 609 = 3045
Step 6: 3045 + 609 = 3654
Step 7: 3654 + 609 = 4263
Step 8: 4263 + 609 = 4872
Step 9: 4872 + 609 = 5481
Step 10: 5481 + 609 = 6090
Step 11: 6090 + 609 = 6699
Step 12: 6699 + 609 = 7308

So, 609*12 = 7308
