Logika 1

Zdanie w sensie logicznym jest to takie wyrażenie, które jest prawdziwe albo fałszywe.
Zmienna zdaniowa jest to takie wyrażenie, za które wolno wstawić dowolne zdanie w sensie logicznym.
Spójniki logiczne to wyrażenia posiadające tę właściwość, że po dodaniu do nich zdania bądź zdań otrzymuje się nowe zdanie, którego wartość logiczna zależy wyłącznie od wartości logicznej zdania dołączonego.
