Sentence: Walter is a dog and lisa and tom enjoy watching soccer together.
Here the interpretation in predicate logic notation:
dog (walter) Ʌ enjoy-watching-soccer-together (lisa,tom) = FALSE
because dog (walter)= TRUE
- because I(walter)= walter and <walter> is an element of the set I(dog)
- because I(walter)= walter and <walter> is an element of the set I(dog)
but enjoy-watching-soccer-together (lisa,tom) = FALSE
- because I(lisa)= lisa, I(tom)= tom and <lisa,tom> is NOT an element of the set I(enjoy-watching-soccer-together).
- because I(lisa)= lisa, I(tom)= tom and <lisa,tom> is NOT an element of the set I(enjoy-watching-soccer-together).
Conjunction (Ʌ): Both atomic formulae have to be true in order for the complex formula to be true.
