Alright, let's solve this math problem step by step. First, we have the number 506. 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 506 and add it to itself 9 times.
Step 1: 0 + 506 = 506
Step 2: 506 + 506 = 1012
Step 3: 1012 + 506 = 1518
Step 4: 1518 + 506 = 2024
Step 5: 2024 + 506 = 2530
Step 6: 2530 + 506 = 3036
Step 7: 3036 + 506 = 3542
Step 8: 3542 + 506 = 4048
Step 9: 4048 + 506 = 4554

So, 506*9 = 4554
