Let's roll up our sleeves and solve this. We have 234 and we're going to multiply it by 14, essentially adding 234 to itself 14 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
Step 14: 3042 + 234 = 3276

So, 234*14 = 3276
