I have come across an issue with these because I am underuse where the "not" is supposed to be.
Take the following example:
P1: A -> Not B
C: B -> C
The correct answer for premise 2 is: Not A -> C with the Contrastive being Not C -> A
But I put down the following:
A -> Not C with the contrapositive being C -> Not A
I want to know how to differentiate between what variable the not should be put or does this not matter?
Already have an account?
