Let's get this math done. We have 151 and we're going to multiply it by 16. This is the same as taking 151 and adding it to itself 16 times.
Step 1: 0 + 151 = 151
Step 2: 151 + 151 = 302
Step 3: 302 + 151 = 453
Step 4: 453 + 151 = 604
Step 5: 604 + 151 = 755
Step 6: 755 + 151 = 906
Step 7: 906 + 151 = 1057
Step 8: 1057 + 151 = 1208
Step 9: 1208 + 151 = 1359
Step 10: 1359 + 151 = 1510
Step 11: 1510 + 151 = 1661
Step 12: 1661 + 151 = 1812
Step 13: 1812 + 151 = 1963
Step 14: 1963 + 151 = 2114
Step 15: 2114 + 151 = 2265
Step 16: 2265 + 151 = 2416

So, 151*16 = 2416
