Alright, let's solve this math problem step by step. First, we have the number 504. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 38. So, we're going to take the number 504 and add it to itself 38 times.
Step 1: 0 + 504 = 504
Step 2: 504 + 504 = 1008
Step 3: 1008 + 504 = 1512
Step 4: 1512 + 504 = 2016
Step 5: 2016 + 504 = 2520
Step 6: 2520 + 504 = 3024
Step 7: 3024 + 504 = 3528
Step 8: 3528 + 504 = 4032
Step 9: 4032 + 504 = 4536
Step 10: 4536 + 504 = 5040
Step 11: 5040 + 504 = 5544
Step 12: 5544 + 504 = 6048
Step 13: 6048 + 504 = 6552
Step 14: 6552 + 504 = 7056
Step 15: 7056 + 504 = 7560
Step 16: 7560 + 504 = 8064
Step 17: 8064 + 504 = 8568
Step 18: 8568 + 504 = 9072
Step 19: 9072 + 504 = 9576
Step 20: 9576 + 504 = 10080
Step 21: 10080 + 504 = 10584
Step 22: 10584 + 504 = 11088
Step 23: 11088 + 504 = 11592
Step 24: 11592 + 504 = 12096
Step 25: 12096 + 504 = 12600
Step 26: 12600 + 504 = 13104
Step 27: 13104 + 504 = 13608
Step 28: 13608 + 504 = 14112
Step 29: 14112 + 504 = 14616
Step 30: 14616 + 504 = 15120
Step 31: 15120 + 504 = 15624
Step 32: 15624 + 504 = 16128
Step 33: 16128 + 504 = 16632
Step 34: 16632 + 504 = 17136
Step 35: 17136 + 504 = 17640
Step 36: 17640 + 504 = 18144
Step 37: 18144 + 504 = 18648
Step 38: 18648 + 504 = 19152

So, 504*38 = 19152
