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 9. So, we're going to take the number 510 and add it to itself 9 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

So, 510*9 = 4590
