Step 23: 6270 + 285 = 6555
Step 24: 6555 + 285 = 6840
Step 25: 6840 + 285 = 7125
Step 26: 7125 + 285 = 7410
Step 27: 7410 + 285 = 7695
Step 28: 7695 + 285 = 7980
Step 29: 7980 + 285 = 8265
Step 30: 8265 + 285 = 8550
Step 31: 8550 + 285 = 8835
Step 32: 8835 + 285 = 9120
Step 33: 9120 + 285 = 9405
Step 34: 9405 + 285 = 9690
Step 35: 9690 + 285 = 9975
Step 36: 9975 + 285 = 10260
Step 37: 10260 + 285 = 10545
Step 38: 10545 + 285 = 10830
Step 39: 10830 + 285 = 11115
Step 40: 11115 + 285 = 11400
Step 41: 11400 + 285 = 11685
Step 42: 11685 + 285 = 11970
Step 43: 11970 + 285 = 12255
Step 44: 12255 + 285 = 12540
Step 45: 12540 + 285 = 12825
Step 46: 12825 + 285 = 13110
Step 47: 13110 + 285 = 13395
Step 48: 13395 + 285 = 13680
Step 49: 13680 + 285 = 13965
Step 50: 13965 + 285 = 14250

So, 285*50 = 14250
