Alright, let's solve this math problem step by step. First, we have the number 580. 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 580 and add it to itself 42 times.
Step 1: 0 + 580 = 580
Step 2: 580 + 580 = 1160
Step 3: 1160 + 580 = 1740
Step 4: 1740 + 580 = 2320
Step 5: 2320 + 580 = 2900
Step 6: 2900 + 580 = 3480
Step 7: 3480 + 580 = 4060
Step 8: 4060 + 580 = 4640
Step 9: 4640 + 580 = 5220
Step 10: 5220 + 580 = 5800
Step 11: 5800 + 580 = 6380
Step 12: 6380 + 580 = 6960
Step 13: 6960 + 580 = 7540
Step 14: 7540 + 580 = 8120
Step 15: 8120 + 580 = 8700
Step 16: 8700 + 580 = 9280
Step 17: 9280 + 580 = 9860
Step 18: 9860 + 580 = 10440
Step 19: 10440 + 580 = 11020
Step 20: 11020 + 580 = 11600
Step 21: 11600 + 580 = 12180
Step 22: 12180 + 580 = 12760
Step 23: 12760 + 580 = 13340
Step 24: 13340 + 580 = 13920
Step 25: 13920 + 580 = 14500
Step 26: 14500 + 580 = 15080
Step 27: 15080 + 580 = 15660
Step 28: 15660 + 580 = 16240
Step 29: 16240 + 580 = 16820
Step 30: 16820 + 580 = 17400
Step 31: 17400 + 580 = 17980
Step 32: 17980 + 580 = 18560
Step 33: 18560 + 580 = 19140
Step 34: 19140 + 580 = 19720
Step 35: 19720 + 580 = 20300
Step 36: 20300 + 580 = 20880
Step 37: 20880 + 580 = 21460
Step 38: 21460 + 580 = 22040
Step 39: 22040 + 580 = 22620
Step 40: 22620 + 580 = 23200
Step 41: 23200 + 580 = 23780
Step 42: 23780 + 580 = 24360

So, 580*42 = 24360
