a propositional p is given with p :If christmas lasts to easter, I get more presents.
a) Form the negation to the propositional p
b) Form the contrapositive form to the propositional.
a) If christmas won't last to easter, I won't get more presents ..
b) Christmas lasts to easter, so I will get more presents..
Is anyone of that even slightly right, I missed a few classes so I don't know that much sadly =/
Ok, I think I got some of it.
a) Christmas lasts to easter, I won't get any more presents.
b) I won't get anymore presents, so Christmas won't last to easter.
I think b) is right, but not too sure about a) (negation)
Great link btw :)
