Distributive laws for Boolean logic and arithmetic:

a OR (b AND c) = (a OR b) AND (a OR c)

a + (b * c) = a + (b * c)

a AND (b OR c) = (a AND b) OR (a AND c)

a * (b + c) = (a * b) + (a * c)

i.e. AND distributes over OR and vice versa. Multiplication always distributes over addition and not vice versa. Probably a few other fundamental differences too.

I don't understand the appeal - posting simply for the sake of being "first" isn't exactly the most respectable of intentions, honestly, the people who read the replies aren't normally going to care who wrote what when, just what's in the response. - If your response is generally good, people will read it and enjoy it anyway. - Simply posting "woo I got first post" is bound to get you modded down a few points (like this has been) and hnce you'll hardly be seen at all.
