Logic questions. Help!!!!

<p>I kinda have a problem with Logic questions. I use Sparknotes and they don't cover much. So, please can any give the basic rules. or example, I totally don't understand question 45 of Math ii test 2 on the Official CB Math Level I and II. Is there a helpful site or can anyone list the basic rules.</p>

<p>I Know Logic questions might just occur once or even not at all in a test. But I still just wanna know.</p>

<p>Logic is like
If P, then Q?</p>

<p>Usually if they say "if P, then Q"
Then its "if NOT P, then NOT Q", not considering other variables in the question.
adjust accordingly</p>
