Negation normal form

Negation Normal Form is a special way to write down logical statements or sentences. If you want to say something is true or false, you can do it by using different words like "and", "or", "not", and "if".

Now imagine that you have a very complicated sentence with a lot of these words in it. It might be difficult to understand what it is saying. Negation Normal Form is a way to simplify these sentences so that they are easier to understand.

In Negation Normal Form, all of the "nots" must come before the variables or propositions that they are talking about. For example, instead of saying "not A and B", you would say "not A or not B".

You also need to make sure that all of the variables and propositions are either "and"ed or "ored" together. For example, instead of saying "A and not B", you would say "A and B or A and not B".

When a sentence is in Negation Normal Form, it is easier to see what it is saying and to see what the different parts of the sentence are doing. This can be very helpful when you are trying to understand a complicated argument or when you are trying to write your own logical statements.
