Alright, let's solve this math problem step by step. First, we have the number 396. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 12. So, we're going to take the number 396 and add it to itself 12 times.
Step 1: 0 + 396 = 396
Step 2: 396 + 396 = 792
Step 3: 792 + 396 = 1188
Step 4: 1188 + 396 = 1584
Step 5: 1584 + 396 = 1980
Step 6: 1980 + 396 = 2376
Step 7: 2376 + 396 = 2772
Step 8: 2772 + 396 = 3168
Step 9: 3168 + 396 = 3564
Step 10: 3564 + 396 = 3960
Step 11: 3960 + 396 = 4356
Step 12: 4356 + 396 = 4752

So, 396*12 = 4752
