Ex.9) AuB={0,1,2,3,4,5,7,8}                   o sa iti pun semnul π pentru intersectat.
BuC={0,1,2,3,4,5,6,8}
CuE={0,1,2,3,4,6,8}
BuCuD={0,1,2,3,4,5,6,7,8,9}
BπC={4}
AπE={1,2,,4,8}
DπE={1,3}
A\B={7}
B\C={0,1,3,5}
D\E={5,7,9}
E\C={0,1,3}
B\A={0,3,5}
(AuB)πE={ 0,1,2,3,48}
(BuC)π(AuE)={0,1,2,3,4,8}
pe ultimele doua nu le stiu

ex.10) AuB={0,1,2,3,4,5,6}
AπC={1,2,3}
AuC={1,2,3,4,5,6,7}
BπC={2,4,6}
A\B={5}
B\A={0,4,6}
C\A={4,6,7}
B\C={0,1}
(AuB)πC={2,3,4,6}
(AuB)π(BuC)={0,1,2,3,4,5,6,7}
Aπ(CπB)={2}

ex.13) x={4,5,6,7}

ex.14) n={9}

ex.2) AuB={1,2,3,7,8}
BπA={7}
A\B={1,2,3}
B\A={8}

ex. 6. nu stiu sa il fac.
SPER CA TE-M AJUTAT :)
