Let's roll up our sleeves and solve this. We have 599 and we're going to multiply it by 14, essentially adding 599 to itself 14 times.
Step 1: 0 + 599 = 599
Step 2: 599 + 599 = 1198
Step 3: 1198 + 599 = 1797
Step 4: 1797 + 599 = 2396
Step 5: 2396 + 599 = 2995
Step 6: 2995 + 599 = 3594
Step 7: 3594 + 599 = 4193
Step 8: 4193 + 599 = 4792
Step 9: 4792 + 599 = 5391
Step 10: 5391 + 599 = 5990
Step 11: 5990 + 599 = 6589
Step 12: 6589 + 599 = 7188
Step 13: 7188 + 599 = 7787
Step 14: 7787 + 599 = 8386

So, 599*14 = 8386
