conversations.value: If Brian previously had 20 video games but lost 5, that means he now has 20-5=15 video games
  Brian has 15 video games, so if Bobby has 5 fewer than 3 times as many as Brian does we must first perform 15*3=45
  We then subtract 5 from the previous total for 45-5=40 games in total.
