Considering the fact that your question is literally a philosophical enquiry should it really be that difficult for you to produce your own answer? If you're going to rely on other people to do your thinking then at least make the discussion open-ended.

What's a good introductory text or lecture series to get me interested in math again?

The past few years it's seemed like a useless foreign language to me, no doubt because of the half-assed american public school system, and my ever-increasing apathy towards the subject. However, recently I'm starting to see the appeal and really feel I need to build my self back up from the ground level.

Any logicians in here?

Consider an interpretation S.

The universe of S is the set of natural numbers

S(P) is the set of even numbers
S(I) is the set of odd numbers
S(Q) is the set of prime numbers
S(R) is the set of multiples of 2

Now, I need to know which objects satisfy these formulas:

(Pa v Ia) = Any object in the universe will satisfy this one

(Qa ^ Pa) = Only the number 2 can satisfy this one, for it is the only even number that is also a prime

(Ra ^ Ia) = No object in the universe can satisfy this formula, since there is no odd number that is also a multiple of 2

(Ia -> ~Ra) = This is the one I'm having problems with, how do I determine which objects satisfy a conditional?

Thank you for your attention.
