Alright, let's solve this math problem step by step. First, we have the number 510. 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 510 and add it to itself 12 times.
Step 1: 0 + 510 = 510
Step 2: 510 + 510 = 1020
Step 3: 1020 + 510 = 1530
Step 4: 1530 + 510 = 2040
Step 5: 2040 + 510 = 2550
Step 6: 2550 + 510 = 3060
Step 7: 3060 + 510 = 3570
Step 8: 3570 + 510 = 4080
Step 9: 4080 + 510 = 4590
Step 10: 4590 + 510 = 5100
Step 11: 5100 + 510 = 5610
Step 12: 5610 + 510 = 6120

So, 510*12 = 6120
