Let's roll up our sleeves and solve this. We have 318 and we're going to multiply it by 16, essentially adding 318 to itself 16 times.
Step 1: 0 + 318 = 318
Step 2: 318 + 318 = 636
Step 3: 636 + 318 = 954
Step 4: 954 + 318 = 1272
Step 5: 1272 + 318 = 1590
Step 6: 1590 + 318 = 1908
Step 7: 1908 + 318 = 2226
Step 8: 2226 + 318 = 2544
Step 9: 2544 + 318 = 2862
Step 10: 2862 + 318 = 3180
Step 11: 3180 + 318 = 3498
Step 12: 3498 + 318 = 3816
Step 13: 3816 + 318 = 4134
Step 14: 4134 + 318 = 4452
Step 15: 4452 + 318 = 4770
Step 16: 4770 + 318 = 5088

So, 318*16 = 5088
