Without delay, let's solve this. We've got 823 and we will be multiplying it by 34, that is, adding 823 to itself 34 times.
Step 1: 0 + 823 = 823
Step 2: 823 + 823 = 1646
Step 3: 1646 + 823 = 2469
Step 4: 2469 + 823 = 3292
Step 5: 3292 + 823 = 4115
Step 6: 4115 + 823 = 4938
Step 7: 4938 + 823 = 5761
Step 8: 5761 + 823 = 6584
Step 9: 6584 + 823 = 7407
Step 10: 7407 + 823 = 8230
Step 11: 8230 + 823 = 9053
Step 12: 9053 + 823 = 9876
Step 13: 9876 + 823 = 10699
Step 14: 10699 + 823 = 11522
Step 15: 11522 + 823 = 12345
Step 16: 12345 + 823 = 13168
Step 17: 13168 + 823 = 13991
Step 18: 13991 + 823 = 14814
Step 19: 14814 + 823 = 15637
Step 20: 15637 + 823 = 16460
Step 21: 16460 + 823 = 17283
Step 22: 17283 + 823 = 18106
Step 23: 18106 + 823 = 18929
Step 24: 18929 + 823 = 19752
Step 25: 19752 + 823 = 20575
Step 26: 20575 + 823 = 21398
Step 27: 21398 + 823 = 22221
Step 28: 22221 + 823 = 23044
Step 29: 23044 + 823 = 23867
Step 30: 23867 + 823 = 24690
Step 31: 24690 + 823 = 25513
Step 32: 25513 + 823 = 26336
Step 33: 26336 + 823 = 27159
Step 34: 27159 + 823 = 27982

So, 823*34 = 27982
