Alright, let's solve this math problem step by step. First, we have the number 475. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 42. So, we're going to take the number 475 and add it to itself 42 times.
Step 1: 0 + 475 = 475
Step 2: 475 + 475 = 950
Step 3: 950 + 475 = 1425
Step 4: 1425 + 475 = 1900
Step 5: 1900 + 475 = 2375
Step 6: 2375 + 475 = 2850
Step 7: 2850 + 475 = 3325
Step 8: 3325 + 475 = 3800
Step 9: 3800 + 475 = 4275
Step 10: 4275 + 475 = 4750
Step 11: 4750 + 475 = 5225
Step 12: 5225 + 475 = 5700
Step 13: 5700 + 475 = 6175
Step 14: 6175 + 475 = 6650
Step 15: 6650 + 475 = 7125
Step 16: 7125 + 475 = 7600
Step 17: 7600 + 475 = 8075
Step 18: 8075 + 475 = 8550
Step 19: 8550 + 475 = 9025
Step 20: 9025 + 475 = 9500
Step 21: 9500 + 475 = 9975
Step 22: 9975 + 475 = 10450
Step 23: 10450 + 475 = 10925
Step 24: 10925 + 475 = 11400
Step 25: 11400 + 475 = 11875
Step 26: 11875 + 475 = 12350
Step 27: 12350 + 475 = 12825
Step 28: 12825 + 475 = 13300
Step 29: 13300 + 475 = 13775
Step 30: 13775 + 475 = 14250
Step 31: 14250 + 475 = 14725
Step 32: 14725 + 475 = 15200
Step 33: 15200 + 475 = 15675
Step 34: 15675 + 475 = 16150
Step 35: 16150 + 475 = 16625
Step 36: 16625 + 475 = 17100
Step 37: 17100 + 475 = 17575
Step 38: 17575 + 475 = 18050
Step 39: 18050 + 475 = 18525
Step 40: 18525 + 475 = 19000
Step 41: 19000 + 475 = 19475
Step 42: 19475 + 475 = 19950

So, 475*42 = 19950
