Alright, let's solve this math problem step by step. First, we have the number 505. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 34. So, we're going to take the number 505 and add it to itself 34 times.
Step 1: 0 + 505 = 505
Step 2: 505 + 505 = 1010
Step 3: 1010 + 505 = 1515
Step 4: 1515 + 505 = 2020
Step 5: 2020 + 505 = 2525
Step 6: 2525 + 505 = 3030
Step 7: 3030 + 505 = 3535
Step 8: 3535 + 505 = 4040
Step 9: 4040 + 505 = 4545
Step 10: 4545 + 505 = 5050
Step 11: 5050 + 505 = 5555
Step 12: 5555 + 505 = 6060
Step 13: 6060 + 505 = 6565
Step 14: 6565 + 505 = 7070
Step 15: 7070 + 505 = 7575
Step 16: 7575 + 505 = 8080
Step 17: 8080 + 505 = 8585
Step 18: 8585 + 505 = 9090
Step 19: 9090 + 505 = 9595
Step 20: 9595 + 505 = 10100
Step 21: 10100 + 505 = 10605
Step 22: 10605 + 505 = 11110
Step 23: 11110 + 505 = 11615
Step 24: 11615 + 505 = 12120
Step 25: 12120 + 505 = 12625
Step 26: 12625 + 505 = 13130
Step 27: 13130 + 505 = 13635
Step 28: 13635 + 505 = 14140
Step 29: 14140 + 505 = 14645
Step 30: 14645 + 505 = 15150
Step 31: 15150 + 505 = 15655
Step 32: 15655 + 505 = 16160
Step 33: 16160 + 505 = 16665
Step 34: 16665 + 505 = 17170

So, 505*34 = 17170
