Alright, let's solve this math problem step by step. First, we have the number 525. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 17. So, we're going to take the number 525 and add it to itself 17 times.
Step 1: 0 + 525 = 525
Step 2: 525 + 525 = 1050
Step 3: 1050 + 525 = 1575
Step 4: 1575 + 525 = 2100
Step 5: 2100 + 525 = 2625
Step 6: 2625 + 525 = 3150
Step 7: 3150 + 525 = 3675
Step 8: 3675 + 525 = 4200
Step 9: 4200 + 525 = 4725
Step 10: 4725 + 525 = 5250
Step 11: 5250 + 525 = 5775
Step 12: 5775 + 525 = 6300
Step 13: 6300 + 525 = 6825
Step 14: 6825 + 525 = 7350
Step 15: 7350 + 525 = 7875
Step 16: 7875 + 525 = 8400
Step 17: 8400 + 525 = 8925

So, 525*17 = 8925
