Step 15: 3696 + 264 = 3960
Step 16: 3960 + 264 = 4224
Step 17: 4224 + 264 = 4488
Step 18: 4488 + 264 = 4752
Step 19: 4752 + 264 = 5016
Step 20: 5016 + 264 = 5280
Step 21: 5280 + 264 = 5544
Step 22: 5544 + 264 = 5808
Step 23: 5808 + 264 = 6072
Step 24: 6072 + 264 = 6336
Step 25: 6336 + 264 = 6600
Step 26: 6600 + 264 = 6864
Step 27: 6864 + 264 = 7128
Step 28: 7128 + 264 = 7392
Step 29: 7392 + 264 = 7656
Step 30: 7656 + 264 = 7920
Step 31: 7920 + 264 = 8184
Step 32: 8184 + 264 = 8448
Step 33: 8448 + 264 = 8712
Step 34: 8712 + 264 = 8976
Step 35: 8976 + 264 = 9240
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
