Step 3: 1152 + 576 = 1728
Step 4: 1728 + 576 = 2304
Step 5: 2304 + 576 = 2880
Step 6: 2880 + 576 = 3456
Step 7: 3456 + 576 = 4032
Step 8: 4032 + 576 = 4608
Step 9: 4608 + 576 = 5184
Step 10: 5184 + 576 = 5760
Step 11: 5760 + 576 = 6336
Step 12: 6336 + 576 = 6912
Step 13: 6912 + 576 = 7488
Step 14: 7488 + 576 = 8064
Step 15: 8064 + 576 = 8640
Step 16: 8640 + 576 = 9216
Step 17: 9216 + 576 = 9792
Step 18: 9792 + 576 = 10368
Step 19: 10368 + 576 = 10944
Step 20: 10944 + 576 = 11520
Step 21: 11520 + 576 = 12096
Step 22: 12096 + 576 = 12672
Step 23: 12672 + 576 = 13248
Step 24: 13248 + 576 = 13824
Step 25: 13824 + 576 = 14400
Step 26: 14400 + 576 = 14976
Step 27: 14976 + 576 = 15552
Step 28: 15552 + 576 = 16128
Step 29: 16128 + 576 = 16704
Step 30: 16704 + 576 = 17280
Step 31: 17280 + 576 = 17856
Step 32: 17856 + 576 = 18432
Step 33: 18432 + 576 = 19008
Step 34: 19008 + 576 = 19584
Step 35: 19584 + 576 = 20160
Step 36: 20160 + 576 = 20736
Step 37: 20736 + 576 = 21312

So, 576*37 = 21312
