Množiny A a B
Jsou dány množiny A = \{1;4;7;9;12 \} a B = \{–3;0;2;4 \}.
Urči:
\large B- A
\large B- A = \left \{-3;0;4 \right \}
\large B- A = \left \{0;2;4 \right \}
\large B- A = \left \{-3;0;2 \right \}
\large B- A = \left \{-3;2;4 \right \}
Teď uděláš znovu rozdíl, ale s prohozeným pořadím množin. V nově vzniklé množině budou všechny prvky z množiny B, které nepatří do množiny A.
