Step 36: 33600 + 960 = 34560
Step 37: 34560 + 960 = 35520
Step 38: 35520 + 960 = 36480
Step 39: 36480 + 960 = 37440
Step 40: 37440 + 960 = 38400
Step 41: 38400 + 960 = 39360
Step 42: 39360 + 960 = 40320
Step 43: 40320 + 960 = 41280
Step 44: 41280 + 960 = 42240
Step 45: 42240 + 960 = 43200
Step 46: 43200 + 960 = 44160
Step 47: 44160 + 960 = 45120
Step 48: 45120 + 960 = 46080
Step 49: 46080 + 960 = 47040
Step 50: 47040 + 960 = 48000
Step 51: 48000 + 960 = 48960
Step 52: 48960 + 960 = 49920
Step 53: 49920 + 960 = 50880
Step 54: 50880 + 960 = 51840
Step 55: 51840 + 960 = 52800
Step 56: 52800 + 960 = 53760
Step 57: 53760 + 960 = 54720
Step 58: 54720 + 960 = 55680
