Without delay, let's solve this. We've got 251 and we will be multiplying it by 23, that is, adding 251 to itself 23 times.
Step 1: 0 + 251 = 251
Step 2: 251 + 251 = 502
Step 3: 502 + 251 = 753
Step 4: 753 + 251 = 1004
Step 5: 1004 + 251 = 1255
Step 6: 1255 + 251 = 1506
Step 7: 1506 + 251 = 1757
Step 8: 1757 + 251 = 2008
Step 9: 2008 + 251 = 2259
Step 10: 2259 + 251 = 2510
Step 11: 2510 + 251 = 2761
Step 12: 2761 + 251 = 3012
Step 13: 3012 + 251 = 3263
Step 14: 3263 + 251 = 3514
Step 15: 3514 + 251 = 3765
Step 16: 3765 + 251 = 4016
Step 17: 4016 + 251 = 4267
Step 18: 4267 + 251 = 4518
Step 19: 4518 + 251 = 4769
Step 20: 4769 + 251 = 5020
Step 21: 5020 + 251 = 5271
Step 22: 5271 + 251 = 5522
Step 23: 5522 + 251 = 5773

So, 251*23 = 5773
