Alright, let's solve this math problem step by step. First, we have the number 515. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 13. So, we're going to take the number 515 and add it to itself 13 times.
Step 1: 0 + 515 = 515
Step 2: 515 + 515 = 1030
Step 3: 1030 + 515 = 1545
Step 4: 1545 + 515 = 2060
Step 5: 2060 + 515 = 2575
Step 6: 2575 + 515 = 3090
Step 7: 3090 + 515 = 3605
Step 8: 3605 + 515 = 4120
Step 9: 4120 + 515 = 4635
Step 10: 4635 + 515 = 5150
Step 11: 5150 + 515 = 5665
Step 12: 5665 + 515 = 6180
Step 13: 6180 + 515 = 6695

So, 515*13 = 6695
