conversations.value: I'm stuck on this math problem: Dani brings two and half dozen cupcakes for her 2nd-grade class.  There are 27 students (including Dani), 1 teacher, and 1 teacher’s aid.  If 3 students called in sick that day, how many cupcakes are left after Dani gives one to everyone in the class?
  Can you help?

conversations.value: Dani brings 2.5 x 12 = 30 cupcakes.
  She needs this many cupcakes to feed everyone in class 27 + 2 = 29.
  With the 3 students calling in sick, there are this many people in class today 29 - 3 = 26.
  There are this many cupcakes left after everyone gets one 30 - 26 = 4 cupcakes.
