conversations.value: Break down this math problem: John buys 3 boxes of burritos.  He gives away a 3rd of them to his friend.  Each box has 20 burritos.  He eats 3 burritos per day for 10 days.  How many burritos does he have left?

conversations.value: He gave 3/3=1 box away
  So he has 3-1=2 boxes
  So he got 2*20=40 burritos
  He ate 3*10=30 burritos
  So he has 40-30=10 burritos left
