Where is the lesson on negating embedded conditional statements?I just need some clarification now how NOT (A--->B) turns into A and /B.
In (A--->B) ---> C. Couldn't the contrapositive just be
/C---> A--->/B. I am not getting how it gets to /C---> A and /B. -

a unless b but only if c.For instance, a -> (b -> c) simplifies to a + -b -> -c. What about (-a -> b) -> c. How can I simplify it?
To simplify: (-a -> b) -> c, think of the expression (-a -> b) as y. That is, y=(-a -> b). Then, we get
y -> c,
or, -c -> -y (taking contrapositive)
or, -c -> (-a -> b)
or, -c AND -a -> b -
a unless b but only if c.For instance, a -> (b -> c) simplifies to a + -b -> -c. What about (-a -> b) -> c. How can I simplify it?
So,
(A -> B) -> C = not C -> A and not B
(not A -> B) -> C = not C -> not A and not B
A -> (B->C) = A and not B -> C
