A reunit cu B = (11,13,21,31,48,49,55)
A intersectat cu B = (13,31,55)
A reunit cu C = (11,13,21,31,48,49,55)
A intersectat cu C = (11,13,21)
C reunit cu B = (11,13,21,31,48,55)
C intersectat cu B = (13,48)
A intersectat cu (B reunit cu C)
B reunit cu C = (11,13,21,31,48,55) si A intersectat cu (B reunit cu C) = (11,13,21,31,55)
A reunit cu (B intersectat cu C)
B intersectat cu C = (13,48) si A reunit cu (B intersectat cu C) = (11,13,21,31,48,49,55)
Ai grija, sunt acolade, nu paranteze rotunde...

A reunit cu B = {11,13,21,31,48,49,55}
A int. cu B = { 13,31,55 }
A reunit cu C = {11,13,21,31,48,49,55}
A int cu C = {11,13,21}
C reunit cu B = {11,13,21,31,48,55}
C intersectat cu B = {13,48}
A intersectat cu {B reunit cu }
B reunit cu C = {11,13,21,31,48,55}
A intersectat cu B reunit cu C = {11,13,21,31,55}
A reunit cu B intersectat cu C = {11,13,21,31,48,49,55}
