These are not all of the valid argument forms as there is an infinity of valid argument forms. These that we are going to see each have a name because they are very common. Changes are that when you have an argument and it is valid, it will most likely be one of. Feb 15th, 2018 the 10 that we are covering (dn) adding or dropping double negation. Has 2 lines because it works in both directions. If i have a and b, then i have a&b. You have 2 propositions and if they are both true than the following proposition will be true. Therefore the sky is blue and tomatoes are red. If you have a&b than you know that a is true and that b is true. If you have a, you can write a or b because we know that at least one of the propositions is true.
