Let's get this math done. We have 272 and we're going to multiply it by 16. This is the same as taking 272 and adding it to itself 16 times.
Step 1: 0 + 272 = 272
Step 2: 272 + 272 = 544
Step 3: 544 + 272 = 816
Step 4: 816 + 272 = 1088
Step 5: 1088 + 272 = 1360
Step 6: 1360 + 272 = 1632
Step 7: 1632 + 272 = 1904
Step 8: 1904 + 272 = 2176
Step 9: 2176 + 272 = 2448
Step 10: 2448 + 272 = 2720
Step 11: 2720 + 272 = 2992
Step 12: 2992 + 272 = 3264
Step 13: 3264 + 272 = 3536
Step 14: 3536 + 272 = 3808
Step 15: 3808 + 272 = 4080
Step 16: 4080 + 272 = 4352

So, 272*16 = 4352
