This formulae gives me some troubles.
Im getting this far before im in trouble:
How do I push the negation inwards ?
Appreciate all hints or solutions!
Lets say we are dealing with and means .
Then says "some natural number precedes every natural number". Does that imply that "every natural is preceded by some natural number"?
Can you use IE, UI, UG & EU in a valid way to get what you need?
"There exist an X where all Y is in the same function p(X,Y) which implies that for all Y is there an X in the same function p(X,Y)"
First of all i need to remove the imply arrow by negating the right side and split up the left and right part like this:
You can then remove by introducing a new constant for X.
