Alright, let's solve this math problem step by step. First, we have the number 404. 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 404 and add it to itself 42 times.
Step 1: 0 + 404 = 404
Step 2: 404 + 404 = 808
Step 3: 808 + 404 = 1212
Step 4: 1212 + 404 = 1616
Step 5: 1616 + 404 = 2020
Step 6: 2020 + 404 = 2424
Step 7: 2424 + 404 = 2828
Step 8: 2828 + 404 = 3232
Step 9: 3232 + 404 = 3636
Step 10: 3636 + 404 = 4040
Step 11: 4040 + 404 = 4444
Step 12: 4444 + 404 = 4848
Step 13: 4848 + 404 = 5252
Step 14: 5252 + 404 = 5656
Step 15: 5656 + 404 = 6060
Step 16: 6060 + 404 = 6464
Step 17: 6464 + 404 = 6868
Step 18: 6868 + 404 = 7272
Step 19: 7272 + 404 = 7676
Step 20: 7676 + 404 = 8080
Step 21: 8080 + 404 = 8484
Step 22: 8484 + 404 = 8888
Step 23: 8888 + 404 = 9292
Step 24: 9292 + 404 = 9696
Step 25: 9696 + 404 = 10100
Step 26: 10100 + 404 = 10504
Step 27: 10504 + 404 = 10908
Step 28: 10908 + 404 = 11312
Step 29: 11312 + 404 = 11716
Step 30: 11716 + 404 = 12120
Step 31: 12120 + 404 = 12524
Step 32: 12524 + 404 = 12928
Step 33: 12928 + 404 = 13332
Step 34: 13332 + 404 = 13736
Step 35: 13736 + 404 = 14140
Step 36: 14140 + 404 = 14544
Step 37: 14544 + 404 = 14948
Step 38: 14948 + 404 = 15352
Step 39: 15352 + 404 = 15756
Step 40: 15756 + 404 = 16160
Step 41: 16160 + 404 = 16564
Step 42: 16564 + 404 = 16968

So, 404*42 = 16968
