Step 36: 9240 + 264 = 9504
Step 37: 9504 + 264 = 9768
Step 38: 9768 + 264 = 10032
Step 39: 10032 + 264 = 10296
Step 40: 10296 + 264 = 10560
Step 41: 10560 + 264 = 10824
Step 42: 10824 + 264 = 11088
Step 43: 11088 + 264 = 11352
Step 44: 11352 + 264 = 11616
Step 45: 11616 + 264 = 11880
Step 46: 11880 + 264 = 12144
Step 47: 12144 + 264 = 12408
Step 48: 12408 + 264 = 12672
Step 49: 12672 + 264 = 12936
Step 50: 12936 + 264 = 13200
Step 51: 13200 + 264 = 13464
Step 52: 13464 + 264 = 13728
Step 53: 13728 + 264 = 13992
Step 54: 13992 + 264 = 14256
Step 55: 14256 + 264 = 14520

So, 264*55 = 14520
