Cade has six red stamps and three blue ones.
In his collection, seven stamps are from Argentina and six stamps are from Sweden.
One stamp is purple and it is not from Argentina or Sweden.
Two of his Argentine stamps are red and one is blue.
Two of his Swedish stamps are blue and three are red.

What is the minimum number of stamps that Cade can have?
