I'm teaching myself propositional logic at home and I can't understand the difference between these two statements in the book. I think one of these represents that 'age is not between 65 and 80 inclusive', but I'm really not sure. If someone could explain what each of the statements mean that would be great. Then I can carry on with my reading!!
Here are the two I don't know the difference between:
¬ ((age ≥ 65) ∨ (age ≤ 80))
¬ (age ≥ 65) ∨ ¬ (age ≤ 80)
Thanks in advance!
