Alright, let's solve this math problem step by step. First, we have the number 546. 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 546 and add it to itself 12 times.
Step 1: 0 + 546 = 546
Step 2: 546 + 546 = 1092
Step 3: 1092 + 546 = 1638
Step 4: 1638 + 546 = 2184
Step 5: 2184 + 546 = 2730
Step 6: 2730 + 546 = 3276
Step 7: 3276 + 546 = 3822
Step 8: 3822 + 546 = 4368
Step 9: 4368 + 546 = 4914
Step 10: 4914 + 546 = 5460
Step 11: 5460 + 546 = 6006
Step 12: 6006 + 546 = 6552

So, 546*12 = 6552
