conversations.value: Lorraine made a pan of brownies and cut them into 16 pieces.  Her children ate 25% of the brownies when they got home from school.  After dinner,  the entire family ate 50% of the remaining brownies.  After everyone went to bed, Lorraine ate 1 more brownie.  How many brownies are left over?
  Give me a clear explanation.

conversations.value: Her children ate 25% of the 16 brownies so they ate .25*16 = 4 slices
  There were 16 brownies and the children ate 4 slices, leaving 16-4 = 12 brownies
  The family ate 50% of the remaining 12 brownies so they ate .50*12 = 6 brownies
  There were 12 brownies and they ate 6 which leaves 12-6 = 6 brownies
  Lorraine had 1 more of the 6 remaining brownies which leaves 6-1 = 5 brownies
