Without delay, let's solve this. We've got 861 and we will be multiplying it by 34, that is, adding 861 to itself 34 times.
Step 1: 0 + 861 = 861
Step 2: 861 + 861 = 1722
Step 3: 1722 + 861 = 2583
Step 4: 2583 + 861 = 3444
Step 5: 3444 + 861 = 4305
Step 6: 4305 + 861 = 5166
Step 7: 5166 + 861 = 6027
Step 8: 6027 + 861 = 6888
Step 9: 6888 + 861 = 7749
Step 10: 7749 + 861 = 8610
Step 11: 8610 + 861 = 9471
Step 12: 9471 + 861 = 10332
Step 13: 10332 + 861 = 11193
Step 14: 11193 + 861 = 12054
Step 15: 12054 + 861 = 12915
Step 16: 12915 + 861 = 13776
Step 17: 13776 + 861 = 14637
Step 18: 14637 + 861 = 15498
Step 19: 15498 + 861 = 16359
Step 20: 16359 + 861 = 17220
Step 21: 17220 + 861 = 18081
Step 22: 18081 + 861 = 18942
Step 23: 18942 + 861 = 19803
Step 24: 19803 + 861 = 20664
Step 25: 20664 + 861 = 21525
Step 26: 21525 + 861 = 22386
Step 27: 22386 + 861 = 23247
Step 28: 23247 + 861 = 24108
Step 29: 24108 + 861 = 24969
Step 30: 24969 + 861 = 25830
Step 31: 25830 + 861 = 26691
Step 32: 26691 + 861 = 27552
Step 33: 27552 + 861 = 28413
Step 34: 28413 + 861 = 29274

So, 861*34 = 29274
