conversations.value: I'm stuck on this math problem: A food caterer was told to prepare gourmet hot dogs for 36 guests. While most people would only eat one hotdog, he prepared enough for half of the guests to be able to have two hotdogs. However, 40 guests showed up, and everyone wanted a second hotdog. How many guests did not get a second hotdog?
  Can you help?

conversations.value: The food caterer prepared an additional 36/2 = 18 hot dogs.
  Altogether, he prepared 36 + 18 = 54 hotdogs.
  If 40 people wanted seconds, he would have needed 40 x 2 = 80 hot dogs.
  80 - 54 = 26 people did not get second hotdogs.
