Let's get this math done. We have 234 and we're going to multiply it by 16. This is the same as taking 234 and adding it to itself 16 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
Step 15: 3276 + 234 = 3510
Step 16: 3510 + 234 = 3744

So, 234*16 = 3744
