conversations.value: I need help with this problem:
  Steve's new book sells 1,000,000 copies.  He got an advance to pay for 100,000 copies. He gets $2 for each copy of the book sold.  His agent takes 10% of that.  How much money did he keep not counting the money from the advance?
conversations.from: assistant
conversations.value: He sold 1,000,000-100,000=900,000 not counting the advance
  So he made 900,000*2=$1,800,000 from selling the books
  His agent took 1,800,000*.1=$180,000
  That means he kept 1,800,000-180,000=$1,620,000
