conversations.value: Angus, Patrick, and Ollie went fishing for trout on Rainbow Lake.  Angus caught 4 more fish than Patrick did, but Ollie caught 7 fewer fish than Angus.  If Ollie caught 5 fish, how many fish did Patrick catch?

conversations.value: If Ollie caught 7 less than Angus, then Angus caught 5+7=12 fish.
  And since Angus caught four more than Patrick, then Patrick caught 12-4=8 fish.
