conversations.value: I'm stuck on this math problem: John receives $100 from his uncle and gives his sister Jenna 1/4 of that money. He goes and buys groceries worth $40. How much money does John have remaining?
  Can you help?

conversations.value: When John gives his sister 1/4 of his money, he parts with 1/4*100 = 25 dollars
  Johns remains with 100-25 = 75 dollars.
  When he buys groceries worth $40, he remains with 75-40 = 35 dollars
