conversations.value: Gabriel and Luri each own a portable media player that can store up to 100 songs. Gabriel has 20 songs on his player while Luri has 3 times as many songs. How many fewer songs can Luri add to his player than Gabriel can add to his?
  Solve it.

conversations.value: Gabriel can still store 100 - 20 = 80 songs.
  Luri has 20 x 3 = 60 songs stored in his player.
  Thus, Luri can still store 100 - 60 = 40 songs.
  Luri can add 80 - 40 = 40 fewer songs to his player than Gabriel.
