Step 18: 15980 + 940 = 16920
Step 19: 16920 + 940 = 17860
Step 20: 17860 + 940 = 18800
Step 21: 18800 + 940 = 19740
Step 22: 19740 + 940 = 20680
Step 23: 20680 + 940 = 21620
Step 24: 21620 + 940 = 22560
Step 25: 22560 + 940 = 23500
Step 26: 23500 + 940 = 24440
Step 27: 24440 + 940 = 25380
Step 28: 25380 + 940 = 26320
Step 29: 26320 + 940 = 27260
Step 30: 27260 + 940 = 28200
Step 31: 28200 + 940 = 29140
Step 32: 29140 + 940 = 30080
Step 33: 30080 + 940 = 31020
Step 34: 31020 + 940 = 31960
Step 35: 31960 + 940 = 32900
Step 36: 32900 + 940 = 33840
Step 37: 33840 + 940 = 34780
Step 38: 34780 + 940 = 35720
Step 39: 35720 + 940 = 36660
Step 40: 36660 + 940 = 37600
Step 41: 37600 + 940 = 38540
Step 42: 38540 + 940 = 39480
Step 43: 39480 + 940 = 40420
Step 44: 40420 + 940 = 41360
Step 45: 41360 + 940 = 42300
Step 46: 42300 + 940 = 43240
Step 47: 43240 + 940 = 44180
Step 48: 44180 + 940 = 45120
Step 49: 45120 + 940 = 46060
Step 50: 46060 + 940 = 47000
Step 51: 47000 + 940 = 47940
Step 52: 47940 + 940 = 48880
Step 53: 48880 + 940 = 49820
Step 54: 49820 + 940 = 50760
Step 55: 50760 + 940 = 51700
Step 56: 51700 + 940 = 52640
Step 57: 52640 + 940 = 53580

So, 940*57 = 53580
