conversations.value: I need help with this problem:
  Michael has $42. His brother has $17. Michael gives away half the money to his brother. His brother then buys 3 dollars worth of candy. How much money, in dollars, did his brother have in the end?

conversations.value: Michael gives away 42/2=21 dollars.
  His brother then has 21+17=38 dollars.
  In the end, his brother has 38-3=35 dollars.
