Without delay, let's solve this. We've got 234 and we will be multiplying it by 13, that is, adding 234 to itself 13 times.
Step 1: 0 + 234 = 234
Step 2: 234 + 234 = 468
Step 3: 468 + 234 = 702
Step 4: 702 + 234 = 936
Step 5: 936 + 234 = 1170
Step 6: 1170 + 234 = 1404
Step 7: 1404 + 234 = 1638
Step 8: 1638 + 234 = 1872
Step 9: 1872 + 234 = 2106
Step 10: 2106 + 234 = 2340
Step 11: 2340 + 234 = 2574
Step 12: 2574 + 234 = 2808
Step 13: 2808 + 234 = 3042

So, 234*13 = 3042
