Step 23: 10868 + 494 = 11362
Step 24: 11362 + 494 = 11856
Step 25: 11856 + 494 = 12350
Step 26: 12350 + 494 = 12844
Step 27: 12844 + 494 = 13338
Step 28: 13338 + 494 = 13832
Step 29: 13832 + 494 = 14326
Step 30: 14326 + 494 = 14820
Step 31: 14820 + 494 = 15314
Step 32: 15314 + 494 = 15808
Step 33: 15808 + 494 = 16302
Step 34: 16302 + 494 = 16796
Step 35: 16796 + 494 = 17290
Step 36: 17290 + 494 = 17784
Step 37: 17784 + 494 = 18278
Step 38: 18278 + 494 = 18772
Step 39: 18772 + 494 = 19266
Step 40: 19266 + 494 = 19760
Step 41: 19760 + 494 = 20254
Step 42: 20254 + 494 = 20748
Step 43: 20748 + 494 = 21242
Step 44: 21242 + 494 = 21736
Step 45: 21736 + 494 = 22230
Step 46: 22230 + 494 = 22724
Step 47: 22724 + 494 = 23218
Step 48: 23218 + 494 = 23712
Step 49: 23712 + 494 = 24206
Step 50: 24206 + 494 = 24700
Step 51: 24700 + 494 = 25194

So, 494*51 = 25194
