Množinové operace
Jsou dány množiny A = \{1;4;7;9;12 \} a B = \{–3;0;2;4 \}.
Urči:
\large A- B
\large A- B = \left \{4;7;9;12 \right \}
\large A- B = \left \{1;4;9;12 \right \}
\large A- B = \left \{1;4;7;9 \right \}
\large A- B = \left \{1;7;9;12 \right \}
V tomto příkladu děláš rozdíl množin A a B. Rozdíl je v podstatě jako obyčejné odčítání. Z rozdílu vznikne nová množina, kde budou všechny prvky z množiny A, které nepatří do množiny B.
