conversations.value: I'm stuck on this math problem: Every room in a building has at least two windows and a maximum of 4 windows. There are 122 windows total. If 5 rooms have 4 windows and 8 rooms have 3 windows, how many rooms in the building have 2 windows?
  Can you help?

conversations.value: Since 5 rooms have 4 windows, this accounts for 20 windows because 4*5=20 windows.
  Since 8 rooms have 3 windows, this accounts for 24 windows because 8*3=24 windows.
  There are 78 windows left over because 122-20-24 = 78.
  Therefore, there are 39 rooms with 2 windows because 78/2 = 39.
