Without delay, let's solve this. We've got 955 and we will be multiplying it by 23, that is, adding 955 to itself 23 times.
Step 1: 0 + 955 = 955
Step 2: 955 + 955 = 1910
Step 3: 1910 + 955 = 2865
Step 4: 2865 + 955 = 3820
Step 5: 3820 + 955 = 4775
Step 6: 4775 + 955 = 5730
Step 7: 5730 + 955 = 6685
Step 8: 6685 + 955 = 7640
Step 9: 7640 + 955 = 8595
Step 10: 8595 + 955 = 9550
Step 11: 9550 + 955 = 10505
Step 12: 10505 + 955 = 11460
Step 13: 11460 + 955 = 12415
Step 14: 12415 + 955 = 13370
Step 15: 13370 + 955 = 14325
Step 16: 14325 + 955 = 15280
Step 17: 15280 + 955 = 16235
Step 18: 16235 + 955 = 17190
Step 19: 17190 + 955 = 18145
Step 20: 18145 + 955 = 19100
Step 21: 19100 + 955 = 20055
Step 22: 20055 + 955 = 21010
Step 23: 21010 + 955 = 21965

So, 955*23 = 21965
