logica --> nos permite validar e construir argumentos
--> descreve com precisao um algoritmo
proposicao --> sentenca q e verdadeira ou falsa, nao pode ser ambos
negacao --> sempre inverte o valor logico da proposicao (¬p ou ¯p)
and --> quando ambos sao verdade o resultado e verdadeiro tambem (p ∧ q)
or --> quando pelo menos uma proposicao e verdadeira, o resultado tambem sera (p ∨ q)
exclusive-or --> quando um e verdadeiro e o outro e falso, o resultado sera verdadeiro(p ⊕ q)
