conversations.value: I need help with this problem:
  Seven parrots and some crows are perched on a tree branch. There was a noise and the same number of parrots and crows flew away. If only 2 parrots and 1 crow are left on the tree branch now, how many birds were perched on the branch to begin with?

conversations.value: The number of parrots that flew away after the noise is 7-2 = 5
  The same number of crows (5) flew away leaving 1 crow so there were 5+1 = 6 crows to begin with
  The total number of crows and parrots was 7+6 = 13
