Step 25: 5904 + 246 = 6150
Step 26: 6150 + 246 = 6396
Step 27: 6396 + 246 = 6642
Step 28: 6642 + 246 = 6888
Step 29: 6888 + 246 = 7134
Step 30: 7134 + 246 = 7380
Step 31: 7380 + 246 = 7626
Step 32: 7626 + 246 = 7872
Step 33: 7872 + 246 = 8118
Step 34: 8118 + 246 = 8364
Step 35: 8364 + 246 = 8610
Step 36: 8610 + 246 = 8856
Step 37: 8856 + 246 = 9102
Step 38: 9102 + 246 = 9348
Step 39: 9348 + 246 = 9594
Step 40: 9594 + 246 = 9840
Step 41: 9840 + 246 = 10086
Step 42: 10086 + 246 = 10332
Step 43: 10332 + 246 = 10578
Step 44: 10578 + 246 = 10824
Step 45: 10824 + 246 = 11070
Step 46: 11070 + 246 = 11316
Step 47: 11316 + 246 = 11562
Step 48: 11562 + 246 = 11808
Step 49: 11808 + 246 = 12054
Step 50: 12054 + 246 = 12300
Step 51: 12300 + 246 = 12546
Step 52: 12546 + 246 = 12792
Step 53: 12792 + 246 = 13038
Step 54: 13038 + 246 = 13284

So, 246*54 = 13284
