Alright, let's solve this math problem step by step. First, we have the number 450. 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 450 and add it to itself 38 times.
Step 1: 0 + 450 = 450
Step 2: 450 + 450 = 900
Step 3: 900 + 450 = 1350
Step 4: 1350 + 450 = 1800
Step 5: 1800 + 450 = 2250
Step 6: 2250 + 450 = 2700
Step 7: 2700 + 450 = 3150
Step 8: 3150 + 450 = 3600
Step 9: 3600 + 450 = 4050
Step 10: 4050 + 450 = 4500
Step 11: 4500 + 450 = 4950
Step 12: 4950 + 450 = 5400
Step 13: 5400 + 450 = 5850
Step 14: 5850 + 450 = 6300
Step 15: 6300 + 450 = 6750
Step 16: 6750 + 450 = 7200
Step 17: 7200 + 450 = 7650
Step 18: 7650 + 450 = 8100
Step 19: 8100 + 450 = 8550
Step 20: 8550 + 450 = 9000
Step 21: 9000 + 450 = 9450
Step 22: 9450 + 450 = 9900
Step 23: 9900 + 450 = 10350
Step 24: 10350 + 450 = 10800
Step 25: 10800 + 450 = 11250
Step 26: 11250 + 450 = 11700
Step 27: 11700 + 450 = 12150
Step 28: 12150 + 450 = 12600
Step 29: 12600 + 450 = 13050
Step 30: 13050 + 450 = 13500
Step 31: 13500 + 450 = 13950
Step 32: 13950 + 450 = 14400
Step 33: 14400 + 450 = 14850
Step 34: 14850 + 450 = 15300
Step 35: 15300 + 450 = 15750
Step 36: 15750 + 450 = 16200
Step 37: 16200 + 450 = 16650
Step 38: 16650 + 450 = 17100

So, 450*38 = 17100
