Alright, let's solve this math problem step by step. First, we have the number 80. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 57. So, we're going to take the number 80 and add it to itself 57 times.
Step 1: 0 + 80 = 80
Step 2: 80 + 80 = 160
Step 3: 160 + 80 = 240
Step 4: 240 + 80 = 320
Step 5: 320 + 80 = 400
Step 6: 400 + 80 = 480
Step 7: 480 + 80 = 560
Step 8: 560 + 80 = 640
Step 9: 640 + 80 = 720
Step 10: 720 + 80 = 800
Step 11: 800 + 80 = 880
Step 12: 880 + 80 = 960
Step 13: 960 + 80 = 1040
Step 14: 1040 + 80 = 1120
Step 15: 1120 + 80 = 1200
Step 16: 1200 + 80 = 1280
Step 17: 1280 + 80 = 1360
Step 18: 1360 + 80 = 1440
Step 19: 1440 + 80 = 1520
Step 20: 1520 + 80 = 1600
Step 21: 1600 + 80 = 1680
Step 22: 1680 + 80 = 1760
Step 23: 1760 + 80 = 1840
Step 24: 1840 + 80 = 1920
Step 25: 1920 + 80 = 2000
Step 26: 2000 + 80 = 2080
Step 27: 2080 + 80 = 2160
Step 28: 2160 + 80 = 2240
Step 29: 2240 + 80 = 2320
Step 30: 2320 + 80 = 2400
Step 31: 2400 + 80 = 2480
Step 32: 2480 + 80 = 2560
Step 33: 2560 + 80 = 2640
Step 34: 2640 + 80 = 2720
Step 35: 2720 + 80 = 2800
Step 36: 2800 + 80 = 2880
Step 37: 2880 + 80 = 2960
Step 38: 2960 + 80 = 3040
Step 39: 3040 + 80 = 3120
Step 40: 3120 + 80 = 3200
Step 41: 3200 + 80 = 3280
Step 42: 3280 + 80 = 3360
Step 43: 3360 + 80 = 3440
Step 44: 3440 + 80 = 3520
Step 45: 3520 + 80 = 3600
Step 46: 3600 + 80 = 3680
Step 47: 3680 + 80 = 3760
Step 48: 3760 + 80 = 3840
Step 49: 3840 + 80 = 3920
Step 50: 3920 + 80 = 4000
Step 51: 4000 + 80 = 4080
Step 52: 4080 + 80 = 4160
Step 53: 4160 + 80 = 4240
Step 54: 4240 + 80 = 4320
Step 55: 4320 + 80 = 4400
Step 56: 4400 + 80 = 4480
Step 57: 4480 + 80 = 4560

So, 80*57 = 4560
