  Give me a clear explanation.

conversations.value: Earl will have $90 - $28 = $62 after paying off his debt to Fred.
  Fred will have $48 + $28 = $76 after being paid by Earl.
  But then Fred will have $76 - $32 = $44 after paying Greg.
  Greg will have $36 + $32 = $68 after Fred paid him.
  Then, Greg will have $68 - $40 = $28 after paying off his debt to Earl.
  Then, Earl will then have $62 + $40 = $102.
  So together, Greg and Earl will have $28 + $102 = $130.
