Without delay, let's solve this. We've got 63 and we will be multiplying it by 41, that is, adding 63 to itself 41 times.
Step 1: 0 + 63 = 63
Step 2: 63 + 63 = 126
Step 3: 126 + 63 = 189
Step 4: 189 + 63 = 252
Step 5: 252 + 63 = 315
Step 6: 315 + 63 = 378
Step 7: 378 + 63 = 441
Step 8: 441 + 63 = 504
Step 9: 504 + 63 = 567
Step 10: 567 + 63 = 630
Step 11: 630 + 63 = 693
Step 12: 693 + 63 = 756
Step 13: 756 + 63 = 819
Step 14: 819 + 63 = 882
Step 15: 882 + 63 = 945
Step 16: 945 + 63 = 1008
Step 17: 1008 + 63 = 1071
Step 18: 1071 + 63 = 1134
Step 19: 1134 + 63 = 1197
Step 20: 1197 + 63 = 1260
Step 21: 1260 + 63 = 1323
Step 22: 1323 + 63 = 1386
Step 23: 1386 + 63 = 1449
Step 24: 1449 + 63 = 1512
Step 25: 1512 + 63 = 1575
Step 26: 1575 + 63 = 1638
Step 27: 1638 + 63 = 1701
Step 28: 1701 + 63 = 1764
Step 29: 1764 + 63 = 1827
Step 30: 1827 + 63 = 1890
Step 31: 1890 + 63 = 1953
Step 32: 1953 + 63 = 2016
Step 33: 2016 + 63 = 2079
Step 34: 2079 + 63 = 2142
Step 35: 2142 + 63 = 2205
Step 36: 2205 + 63 = 2268
Step 37: 2268 + 63 = 2331
Step 38: 2331 + 63 = 2394
Step 39: 2394 + 63 = 2457
Step 40: 2457 + 63 = 2520
Step 41: 2520 + 63 = 2583

So, 63*41 = 2583
